The phenomenon of "fertilizer damage" will occur when crops are fertilized too much, which is manifested in the following ways: 1. Too much nitrogen fertilizer will prolong the growth period of crops, 2. Too much phosphorus fertilizer will lead to yellowing of crops; 3. Excess potassium destroys soil structure.
-
It is indeed poisoning, and if you apply too much fertilizer, it will also cause crops to wilt and die directly. Therefore, it is necessary to apply fertilizer in moderation.
-
If you apply more fertilizer, you will not be poisoned, because the fertilizer requirements for crops are very high, and the more fertilizer you apply, the better the crops will grow.
-
Yes, so when planting crops, you must control the planting technology and learn the management technology.
-
First, first, apply raw farm manure immediately.
The nutrient content of organic fertilizer is low, and there is no great harm to the growth and development of crops.
Second, excessive application of organic fertilizer.
Unlike organic fertilizer, it is very easy to cauterize seedlings, and the soil organic matter accumulated in the soil can obviously improve the soil. Some people mistakenly believe that the more organic fertilizers they use, the better. Excessive application of organic fertilizers, like organic fertilizers, can also cause adverse effects. The damage manifests itself in the following ways.
Excessive application of organic fertilizer causes burns to seedlings. The application of a lot of organic fertilizer causes the accumulation of phosphorus, potassium and other nutrients in the soil, resulting in soil nutrient imbalance. Large quantities of organic fertilizer were applied, and large quantities of nitrate accumulated in the soil, resulting in excessive phosphate in the crops.
Third, organic chemistry and inorganic matter are not working together enough.
Organic fertilizers have a full range of nutrients, but they are low in content. In order to better meet the nutrient requirements of abundant growth of crops in many aspects, organic fertilizer should be appropriately added on the basis of the application of organic fertilizer. Some manufacturers one-sidedly exaggerate the efficacy of organic fertilizer, only apply organic fertilizer, can not meet the nutrient requirements of crop growth and development, resulting in crop yield.
Fourth, I like cheap organic fertilizers with large amounts.
There are many types of organic fertilizer, and the quality of organic fertilizer produced and processed by different raw materials and methods is very different: for example, the organic fertilizer that farmers accumulate in the field, although the virus inside has already been killed through long-term accumulation and rotting, but because of the long process of alcohol production7 and the leaching effect of precipitation, a large part of the nutrients in it have already been outflowed.
In addition, it is inevitable that some residues such as soil will be brought during the production process, and there is no drying process, so the moisture content in the fertilizer is relatively high. Therefore, although this kind of organic fertilizer has a large volume and net weight, it does give very little organic matter and nutrients to the soil. Taking pig manure as an example, fresh excrement has a higher moisture content, generally 70%, and only a small part of the dry matter, most of which is water.
Therefore, 1 ton of dry organic fertilizer with a moisture content of less than 20% can be produced and processed from fresh excrement up and down.
-
If you apply too much fertilizer, you will not be poisoned, but if you apply too much fertilizer, you will waste fertilizer and will not increase the yield.
-
Yes. If you apply fertilizer regularly, you will be poisoned, and it will also cause some bad conditions in a person's body after eating.
-
Applying too much fertilizer may lead to crop poisoning, so be sure to control the amount of fertilizer.
-
<> the crops planted by farmers, will it really be "poisoned" if they are fertilized too much? Chemical fertilizers can not be used excessively, and they should be applied in accordance with the proportion on the instructions, and the different soil quality and plants should be reasonably arranged. In order to achieve high yields of crops, planting crops is inseparable from fertilizer, and the agricultural proverb says well, crops and flowers all rely on fertilizer.
However, if the fertilizer is not applied properly, it will also cause fertilizer damage, so it is necessary to apply various fertilizers scientifically when planting crops. Generally, fertilizers used for crops are broadly divided into organic fertilizers and chemical fertilizers. Organic fertilizer contains a lot of carbon and a small amount of nutrients, which can maintain soil fertility and yield, but it is difficult to greatly increase the yield, so farmers also use a lot of chemical fertilizers, which are the products of the industrial revolution and the staple food of crops.
If there is no rotting chicken, duck, goose and pig manure, because it contains a large number of heavy metal products, fungi, insects and other harmful substances, therefore, after application, the seeds, buds and roots of crops will cause burns, infection and insect pests, so it will also cause fertilizer damage, therefore, the application of organic farm fertilizer must be treated and then used reasonably, and in an appropriate amount.
When applying chemical fertilizers, we must pay attention to science, choose according to crops, and apply different fertilizers with different ingredients for different crops. The inorganic fast-acting nutrients in chemical fertilizer do not need to be transformed and decomposed by microorganisms, and can be directly absorbed by crop roots after being applied to the soil, and can quickly meet the needs of crops in the vigorous stage of plant growth. Therefore, the application of chemical fertilizers, focusing on pertinence and singleness, there is a clear difference between vegetable fertilizers and field crop fertilizers.
Then the application must be controlled and applied, the nutrients required by crops are limited, the amount of nutrients required in a lifetime is how much, and the infinite excess will cause waste, and even fertilizer damage to crop seeds, buds and root growth. Fake fertilizers cannot be used. Fake fertilizer is harmless.
Whether planting crops is organic fertilizer or chemical fertilizer, we must pay attention to scientific fertilizer, suitable fertilizer, appropriate fertilizer, reasonable fertilizer is!
-
Yes, too much nitrogen fertilizer will prolong the growth time of crops, too much phosphorus fertilizer will cause yellowing of crops, and too much potassium will damage the soil structure and cause vegetable heart rot.
-
In the process of planting crops, it is necessary to apply fertilizer reasonably. Excessive application of fertilizer is likely to result in residues on the surface of crops, which can have an impact on the body.
-
Yes, if you apply too much fertilizer, it will cause the crops to turn yellow, and then it will also damage the soil structure, which will lead to a large reduction in crop yields.
-
Crops should not be fertilized too much, otherwise poisoning will occur. Each crop will be equipped with a certain instruction manual, and fertilizer should be applied according to the proportion. Plants are arranged in different ways, and if you want to get a high yield, you need to use fertilizer properly.
Fertilizers are divided into organic fertilizers and chemical fertilizers, and the supplementation of crops is also different. Some farmers put the manure of their chickens and ducks into their crops, which can promote the growth of crops. After fertilization, the seeds can germinate quickly, and the later growth will be very dense.
Be careful not to put all the fertilizers together when applying fertilizer, as it may poison crops. Fertilizing crops in the soil allows the roots of crops to absorb well, and there are different ways. You should understand how much fertilizer each crop needs to absorb, and don't choose some fake fertilizers.
Some farmers will choose to apply some fertilizer to their crops, depending on how much the crop uses. Reasonable fertilization, crops will grow better. <>
Don't buy fake fertilizer cheaply, as it will cause crops to not grow. If you want to have a good harvest, when you choose fertilizer, you must help the growth of fertilizer. For example, most farmers in rural areas will choose to plant rice, and if there is no good fertilizer, there is no way to make rice grow.
If the fertilizer is not well absorbed by the crops, it will hinder the development of the crops. <>
In general, the nutrients needed by crops are limited, and it is not possible to fertilize as much as you want. If you want to avoid waste, don't let yourself adjust a lot at one time, and fertilize slowly. In the process of fertilization, it is necessary to gradually advance and fertilize all corners.
The degree of fertilizer required for vegetables and rice is different, and it must be targeted.
-
Yes, after all, over-fertilization can lead to soil deterioration and damage to the roots of crops. This is due to the very high chemical dynamics of fertilizers, and these chemical additives may cause the soil to deteriorate.
-
Yes, if you don't apply fertilizer properly, the crops will turn yellow, or the crops will wilt, so there will really be poisoning.
-
Yes. If the fertilizer is not used correctly according to the instructions, it will cause the crops to burn and also cause the crops to die.
-
Yes, if too much fertilizer is put in, the seedlings will be burned, which will affect the health of the leaves and eventually affect the yield.
-
The most important cause of fertilizer damage to crops is also caused by unscientific fertilization. In the case of fertilization, we should control chemical fertilizers and carry out effective and reasonable fertilization according to the regularity of fertilizer demand of different crops and the fertilizer supply characteristics of the soil layer. Before fertilization, we should first accurately measure the soil layer and adjust the concentration value of various fertilizers.
In particular, basal fertilizer and leaf fertilizer should not be used too much. It can reasonably increase the amount of organic fertilizer, but in the case of organic fertilizer, it must be sufficiently manure. In particular, all kinds of organic fertilizers should be applied in conjunction with organic fertilizers after alcohol.
Subsequently, in the case of fertilization, we need to pay attention to moderately increasing the proportion of microbial fertilizer. Microbial fertilizers generally contain nutrients such as phosphorus-solubility and potassium-solubilizing elements of nitrogen-fixing bacteria, which can inhibit the theme activities of pathogens at the roots of crops. It can also play a good buffering role in the microbial flora of the soil environment.
It can improve the soil structure, reduce the prevalence of diseases, and improve the drought resistance of crops. But in the case of fertilization, we should pay attention to the fertilization method. For example, in the case of applying organic fertilizer, especially basal fertilizer, it cannot be applied immediately, and at least 5 cm of deep fertilization should be maintained.
When planting crops, top dressing is essential. When topdressing, we must pay attention to the fertilization site and maintain a certain distance from the crops. Generally, chemical fertilizers should be maintained at least 10cm before and after the roots, and furrow application should be the dominant.
After topdressing, the soil should be covered in time to prevent damage to fertility. If the soil moisture is not enough, then we need to pay attention to the watering work after top dressing to avoid too much heat generated by the fertilizer and cause root burning. In the case of spraying leaf fertilizer, we should pay attention to controlling the concentration values of various elements.
Planting fertilizer is an indispensable work when planting crops. However, in the case of fertilization, we should note that the fertiliser cannot come into direct contact with the seeds. It is necessary to ensure that the seed fertilizer is in a disordered situation, and it is necessary to pay attention to controlling the amount of seed fertilizer used, and never use too much.
Moreover, it is forbidden to use organic fertilizers such as potassium nitrate and urea solution to carry out seed dressing. The calorific value caused by organic fertilizer is very large, and it is very easy to burn seeds, burn seedlings and other fertilizer damage.
-
I think they should be killed with pesticides. Or if you need to water more, you can promote the growth of crops. Let them boost their immunity.
-
You can use some natural fertilizers, so that you can reduce the harm of traditional fertilizers.
-
Be sure to fertilize reasonably, don't fertilize too much at one time, mainly top dressing, be sure to water frequently, and the light must be sufficient.
-
To be fertilized reasonably, fertilizer as small as possible many times, to prevent the phenomenon of burning seedlings due to too high concentration, can be kept away from the roots of crops when fertilizing, to prevent fertilizer from having too much heat to cause root burning, in addition to fertilization should be accompanied by watering.
-
Chemical fertilizer is certified by food supervision on a certain basis, and is only used as a surface work for crops, and will not cause any substantial harm to the human body, unless it is direct contact or accidental consumption of chemical fertilizer, which will cause great harm to the body.
-
The nitric acid in the fertilizer is reduced by human bacteria to nitrite, which is a carcinogen that causes cancer. There is too little "green food" in the three meals of the Chinese. Fertilizer has become the biggest potential killer in our food mix, and it's hard to get rid of it.
Toxins form after a long-term accumulation in our body.
-
It will not have too serious effects, as long as the scientific use of chemical fertilizers, it will not bring harm to the body, do not use it excessively.
-
It will not be harmful to the human body, because the crops have already absorbed these fertilizers during the growth process, and the fertilizers that have not been absorbed are also decomposed in nature.
-
It can cause poisoning symptoms to the human body. At present, the chemical fertilizers used in rural areas in China mainly include nitrogen fertilizers (such as ammonium bicarbonate, urea, etc.), phosphate fertilizers (such as superphosphate, calcium phosphate, etc.) and potassium fertilizers. In addition to potassium fertilizer, which has no obvious harm to the human body, nitrogen fertilizer and phosphate fertilizer have great toxic effects on the human body.
Long-term consumption of foods containing pesticides can lead to the accumulation of pesticides in the body, causing chronic poisoning, triggering a variety of chronic diseases, including cancer and neurological diseases, and reducing immunity.
-
Look at the amount used, the amount used is just enough to be absorbed by crops, but if the amount used is too much, it will accumulate in the crop body, and the human body will also absorb the chemical fertilizer components after absorption, which will have a certain harm.
-
Why is it harmful for humans to use chemical fertilizers on crops? Today, people advocate non-polluting, organic, environmentally friendly and other fashion concepts. For those who are generally considered organic without the use of fertilizers, it seems that the use of fertilizers is harmful to the human body.
However, this is really not the case. Let's talk about personal opinions. Are agricultural products harmful to humans?
First. Why is organic food high?
In people's minds, it seems that expensive would be fine. For example, buy an Apple X phone for 8000 yuan, buy a Xiaomi phone for 2000 yuan, ** high, but sometimes it's not true, Xiaomi mixes it out. At this time, more than 3,000 yuan, starting from market feedback, who does not agree that the hybrid is further than the Apple phone at that time?
And the same is true for agricultural products. If you go into the supermarket and there are only two words, ** 2 times higher than regular vegetables, is this really nutritious, because organic vegetables are more nutritious than fertilizer vegetables? Only organic vegetables are too expensive to produce.
For example, organic vegetables should use a lot of organic fertilizers to maintain production, organic fertilizers are low, **high, and organic agricultural products are pulled up directly. Moreover, even if the unit production of organic vegetables is difficult to compare with agricultural products used in the same fertilizer, it is not difficult to understand that organic agricultural products are not difficult to understand.
Second. Is organic farming more nutritious?
For agricultural nutrition, the nutrition of agricultural products is that the soil can contain all the nutrients, and they need to avoid problems such as detergents in growth and development. And everyone should know that during the growth of crops, especially in the process of reproductive growth, once the nutrition ** is insufficient, there will be symptoms.
In the production of organic agricultural products, especially in the reproductive growth phase, the problem of lack of agricultural nutrition** is often lacking in problems and it is difficult to maintain normality and have symptoms. Nature has an impact on quality. This is not to say that the farmland used for fertilizer will be able to ensure a balance of plant nutrient requirements, but it can reduce the likelihood of decking and improve product quality.
There is also a related study on the nutritional value of organic agricultural products and the nutritional value of ordinary agricultural products.
Third. Are organic produce safer?
It's real! Although the ** of organic agricultural products is higher, due to the avoidance of pesticides and the absence of an agricultural attitude, it is very safe, especially in today's people's awareness of agricultural products. Improve instantly.
In short, I think that ordinary agricultural products are not safe, but I believe that the nutrition of agricultural products will be more comprehensive, more qualified, more valuable after the use of fertilizers, and most importantly, cheaper, cheaper. Of course, if you can buy organic produce from a safety point of view, just now an organic marketer, do you believe in such organic produce?
Of all the fruits, strawberries have always been high. A kilogram of strawberries on the market is about 15 yuan, or even higher. There are seven or eight strawberry growers in greenhouses, with a high yield of more than 5,000 catties per mu and a low yield of more than 3,500 catties. >>>More
Now the planting is relatively regional, for example: green onions are Zhangqiu, apples are Yantai, these are very strong regional planting, and the overall output is very large. It is impossible to completely digest locally, which involves cross-regional sales, and various places can choose some characteristic vegetable varieties according to the actual needs of production for the construction and production of vegetable greenhouses, such as rare vegetables, special dishes, wild vegetables, etc., through the construction of vegetable greenhouse cultivation, in order to meet the diversified needs of the market for vegetable varieties. >>>More
The most important cause of fertilizer damage to crops is also caused by unscientific fertilization. In the case of fertilization, we should control chemical fertilizers and carry out effective and reasonable fertilization according to the regularity of fertilizer demand of different crops and the fertilizer supply characteristics of the soil layer. Before fertilization, we should first accurately measure the soil layer and adjust the concentration value of various fertilizers. >>>More
If the water resources are convenient, the sandy soil is suitable for planting many crops, such as root vegetables, green vegetables, onions, ginger and garlic, eggplant fruits, melon vegetables, bean foods, potatoes, Chinese cabbage, etc., it is a better soil natural environment for the growth and development of the root system, which can make the crop root system more developed, and the crops absorb more nutrients and grow and develop well, but if the water resources are not convenient, then it is suitable to plant crops with deep roots and deep burial, such as melons and cantaloupe. >>>More
For agricultural growers, their most important income in a year is the income obtained from the planting, growth, and sale of crops after maturity, generally speaking, the most important thing to grow crops is the climate problem, but the climate is very changeable as a relatively changeable thing, usually crops will also be affected by climate disasters, then rural crops are the biggest natural disasters. >>>More
