When growing vegetables in rural areas, is it to fertilize first and then plough the land, or to fer

When planting vegetables in rural areas, it should be fertilized first and then cultivated, and the effect is better. The benefits are mainly reflected in three aspects: First, it can ensure that the fertilizer enters the soil during the cultivation process and prevents it from being washed away by water.

Second, it is inevitable that fertilizer will accumulate and not disperse when fertilization is applied first. Over time, the soil will clump and pests and diseases will occur during the growth of vegetables. The use of fertilization first and then cultivated land can effectively prevent the accumulation of fertilizer.

3. Add disinfectants in the process of fertilization, so that when plowing the soil, these disinfectants enter the soil with the fertilizer and play a role in disinfecting the soil. Therefore, it is better to apply fertilizer before planting and then disinfect.

The cultivation of the soil is also very scientific, due to the short growth cycle of vegetables and the high planting density. This puts a high demand on the soil. In order to facilitate the germination and growth of vegetables, it is necessary to divide the soil into multiple tillings.

First of all, a large area is cultivated once, and after the ploughing, a large piece of soil is broken up to prevent the germination of seeds. When using a ploughing machine, it is necessary to plow the land 3 to 5 times, which can ensure that the soil is soft and there are no large pieces of soil, and improve the seed germination rate.

Planting vegetables pays attention to fertilization first, and the choice of fertilizer is mainly organic fertilizer, which generally accounts for about 60% of the total amount of fertilizer. In particular, organic fertilizer will be selected for the base fertilizer, and the necessary fermentation should be carried out before the use of organic fertilizer to ensure that the fermentation is in place. Because if you don't ferment in advance, there will be a second fermentation after applying chemical fertilizers to the soil, and the heat generated by fermentation will burn out the capillary roots of vegetables.

Since the growth cycle of vegetables is generally two or three months, do not use long-lasting fertilizers. Nitrogen, phosphorus and potassium can be applied in small amounts during the growth process.

and other fertilizers to promote the nutritional balance of vegetables. At the same time, it is also necessary to apply a certain amount of foliar fertilizer to ensure the normal growth and development of vegetables.

To grow vegetables scientifically, it is necessary to cultivate land and fertilize reasonably. And generally fertilize first and then plough the land, and the use of fertilizer is generally to choose fermented organic fertilizer. Fermented organic fertilizer contains a lot of probiotics.

It can play a role in balancing soil nutrients. Although there are different ways to grow different vegetables, it is important to pay attention to science.

Fertilizer is applied first and then cultivated the land, because in this way, the fertilizer can be fully dissolved in the soil, which can effectively prevent the accumulation of fertilizer.

It is necessary to fertilize the land before cultivating the land, so that the organic content of the soil can be improved, which will make the plants grow better.

Be sure to fertilize first and then plough the land, which can improve the utilization rate of fertilizer and avoid being washed away by rain.

Base fertilizer, also known as base fertilizer, is to provide nutrients for all stages of vegetable growth, and can also play a role in improving the soil environment for vegetable growth, so the answer is obviously to apply base fertilizer before planting vegetables.

When applying base fertilizer when growing vegetables, the following aspects are mainly considered:

First, the type of base fertilizer applied

Generally speaking, it is more suitable as a base fertilizer, mainly organic fertilizer, such as pigs, cattle and other animal manure, cake fertilizer, green manure, etc., these fertilizers have a long fertilizer effect time and can ensure the nutrients required in the vegetable growth cycle. In addition, some vegan fertilizers (nitrogen, phosphorus, potassium, microbial fertilizers) should be appropriately added to the application of base fertilizer, which is conducive to the growth of vegetable seedlings.

Second, the amount of base fertilizer applied

The amount of base fertilizer to be applied must take into account the fertility of the soil and the variety of vegetables to be grown. Excessive application of base fertilizer will not only waste fertility, but also cause large changes in the soil environment (such as pH value, soil temperature), which is not conducive to the growth of vegetables. If you apply too little, you will have insufficient fertility.

3. The depth of application of base fertilizer

The application depth has a certain relationship with the depth of the soil layer of each vegetable species, generally speaking, the base fertilizer should be applied to the position that the root system of the whole crop in each growth period can reach, and the effect of two applications is better at 5 cm and 15 cm below the soil layer of the cultivated surface.

Summary: Fertilizer must be applied before planting vegetables, but it is best not to consider what kind of fertilizer to apply, and it is best not to use chemical fertilizer, because the fertilizer effect is too long, and the vegetable growth cycle is not good for the human body, and the fertilizer input is not small. It is best to apply farmhouse fertilizer, that is to say, animal manure, farmhouse fertilizer is not tight to improve the soil, but also healthier than chemical fertilizer, before planting vegetables, first raise farmhouse fertilizer to the ground at one time, with a rotary tiller several times, so that farmhouse fertilizer is fully mixed with the land, farmhouse fertilizer is not enough can also be on organic fertilizer, so that the vegetables grown out are not only healthy, but also resistant to transportation, the taste is good, our own yard never on the fertilizer, are all kinds of vegetables grown at home, this kind of vegetables are rarely sick.

Yes, the base fertilizer can provide a certain amount of nutrients to the land, and the vegetables will grow better, and there is no need to fertilize often in the future.

To be applied, this can ensure the growth rate of vegetables. It can improve the survival rate. It can also increase the yield of plants and prevent diseases.

Yes, because the application of base fertilizer can guarantee the normal growth of vegetables, and then it can also be high-yielding.

Before planting vegetables, the land should apply some organic fertilizer, and the growth of vegetables will be better. Plantar fertilizer is applied at the time of planting; During the rapid growth period, different fertilizers such as nitrogen, phosphorus, potassium and trace elements were applied according to the lack of fertilizer in vegetables; In the early stage of harvest, if there is a shortage of fertilizer, fertilizer should also be applied.

The application of basal fertilizer is generally carried out in combination with land preparation, and the base fertilizer is generally best to release organic fertilizer slowly, such as cow manure, sheep manure, chicken manure, cow manure, and sheep manure. In addition to being able to slow fertilization, it can also play a role in loosening the soil, the use method is very simple, sprinkle the fertilizer on the soil, and turn over the ground, so that the soil and fertilizer can be combined.

In recent years, many farmers will choose to grow their own vegetables to meet the needs of family diet, planting vegetables need to do a good job of management measures, such as fertilization is a very important work, the following together from leafy vegetables, nightshade vegetables, root vegetables and precautions to learn more.

1.Leafy vegetables leafy vegetables can be fertilized a week after planting, because leafy vegetables have high requirements for soil quick-acting nutrients and are more sensitive, if there is a lack of nutrients, there will be a slowdown in leaf growth, and the leaves will turn yellow, so in the leafy vegetables to be topdressed in time, every 15-30 days you need to apply farmhouse fertilizer.

2.Nightshade vegetablesWhen nightshade vegetables grow to 3-4 leaves, they can be fertilized. In the seedling stage, more nitrogen fertilizer is needed, but too much nitrogen fertilizer will cause the plant to grow, so pay attention to the amount of nitrogen fertilizer.

After entering the growth period, the demand for phosphate fertilizer of nightshade vegetables increases, so it is necessary to reduce the application of nitrogen fertilizer and focus on increasing the application of phosphorus fertilizer and potassium fertilizer. When the fruit is done, it needs to be supplemented with fertilizer water after each harvest.

3.Root vegetablesWhen the root vegetables grow to 4-5 cm, you can apply fertilizer for the first time. It needs to be fertilized with more nitrogen fertilizer in the early stages of its growth, as this can promote the growth of leaves.

Potassium fertilizer needs to be applied in the middle and late stages of growth, and the amount of nitrogen fertilizer needs to be properly controlled at this time, because too much nitrogen fertilizer in the later stage will lead to the growth of vegetables, the yield will decrease, and the quality will deteriorate.

4.Precautions When fertilizing, you need to pay attention to the fertilizer should be far away from the roots, otherwise it is easy to cause root burns. If there are enough nutrients in the soil, you need to reduce the number of fertilizations.

For plots with soil pH less than 5 in vegetable plots, 50-100 kg of quicklime or 50-100 kg of soil conditioner should be sprinkled per mu one week before planting to increase soil pH and supplement calcium. When the symptoms of molybdenum deficiency appear in the middle and late stages of vegetable growth, foliar spraying with ammonium molybdate aqueous solution (can also be mixed with pesticides), sprayed once every 5-6 days, sprayed twice.

(1) Shallow or superficial fertilization. Fertilizer is volatile, lost or difficult to reach the roots of crops, which is not conducive to crop absorption, resulting in low fertilizer utilization rate. Fertilizer should be applied 16 to 26 cm below the side of the seed or plant.

2) Apply dichloride fertilizer. The compound fertilizer produced with ammonium chloride and potassium chloride is called dichlorofertilizer, which contains about 30% chlorine, is easy to burn seedlings, and should be watered in time. Chlorine-containing fertilizers should not be applied to saline land and chlorine-sensitive crops.

Excessive application of potassium chloride to leaf (stem) vegetables will not only cause vegetables to be not fresh and tender, with more fiber, but also make vegetables taste bitter, poor in taste and low in efficiency. The urea-based compound fertilizer has high nitrogen content, and the content of biuret is also slightly higher, and it is easy to burn seedlings, so it is necessary to pay attention to the depth of watering and fertilization.

One month after planting, you can fertilize, the fertilizer is mainly organic fertilizer, the concentration of fertilizer should not be too high, do not water after fertilization. Thereafter, fertilize every half month.

Generally speaking, chemical fertilizers will reduce the quality of crops, which is not conducive to the use of crops with a long growth cycle, so we need to pay attention to the fact that we should try to choose farmhouse fertilizers, so that it can be better conducive to plant absorption, so as to achieve the purpose of high yield.

Farm fertilizer is a natural fertilizer, applied to crops, and the soil is also very easy to be absorbed by plants, so for the choice of fertilizer, we should try to choose farm fertilizer. However, we need to pay attention to a very big disadvantage of farmhouse fertilizer, that is, slow fertilizer, so we should also choose fertilizer according to our own vegetables.

Farm fertilizer will make vegetables grow better, and then there are no chemicals, pure green vegetables, such vegetables are healthier, although chemical fertilizers can also make vegetables grow well, but there are some chemicals that will have an impact on vegetables.

During the vegetable planting period, the difference between the application of chemical fertilizer and the application of farmhouse fertilizer to the growth of vegetables is: the fertilizer on the vegetable is better than the application of farmhouse fertilizer, and now the mixed use of farmhouse fertilizer and chemical fertilizer is advocated, the farmer's fertilizer contains nutrients comprehensively, a wide range of types, but the content is relatively small, it is difficult to reasonably ** and regulate the various nutrients necessary for crops, at the same time, the fertilizer effect is slow and is not conducive to the direct absorption of crops, and it is more difficult to meet the demand for nutrients in different growth periods, although the nutrients of chemical fertilizer are single, but the fertilizer effect is faster.

One of the issues that often comes to mind in daily life is also a topic of common concern. This is very representative for people who care about and eat green vegetables and fruits! This is also an important topic about green food that people are generally concerned about today.

Let me share some of my observations.

We know that chemical fertilizers and pesticides are often used in the production of food crops today. However, when it comes to the health benefits of this fertilizer, I feel that there are pros and cons. Nowadays, most of the vegetables purchased at farmers' markets must be fertilized to grow bright and lush.

Especially the vegetables grown in the greenhouse, because the fertilizer is mostly stimulated by chemical fertilizer, ripening, picked from the greenhouse, to the people buy it home, the most obvious thing is that it is placed for a long time and does not rot. For example, big road vegetables such as loofahs, green beans, green vegetables, rape, etc., not only do not taste very good, but also do not have the taste of vegetables grown with farmhouse fertilizer in the past, and they are not soft to eat. This is one of the most obvious characteristics of vegetables grown and developed after the use of chemical fertilizers.

The use of organic fertilizer with alcohol compost, the vegetables planted are just the opposite, not only the color of the vegetable tea is dense and shiny, and the growth is also very abundant, after picking, whether it is fried or stewed, the taste is very good. The most popular thing for the common people is the vegetables grown by the farm, but unfortunately it is difficult to buy them now. The vegetables planted by the farmer are not only safe to eat, but also taste quite soft, not like the vegetables fed by chemical fertilizers, there is no vegetable taste, and it is so difficult to swallow!

People in the village use the compost farmer's fertilizer to grow vegetables, generally keep it for their own consumption, and rarely get it to the farmers' market to sell, so many people say that if the village uses organic fertilizer to grow vegetables, even if the price is twice as high as that of chemical fertilizer, they would rather buy vegetables grown by farms. And below this is also what these farmers who grow vegetable greenhouses often say: they can generally vacate a small piece of land for themselves, and use farm fertilizer to grow enough vegetables for themselves and their families to eat, and will never use chemical fertilizers and pesticides to grow vegetables for themselves and their families.

Too little fertilization can adversely affect the growth of vegetables, and too much fertilization can also have a detrimental effect on vegetables. Let's talk about the adverse effects of too much fertilization.

Enumerate: 1: Nitrogen fertilizer is a fertilizer that is conducive to plant growth and development, but if the fertilizer is too excessive and the amount is too high, it will cause the leaves to be dark green or even yellow, and will lead to a great increase in the nitrate content in vegetables.

For example, too much nitrogen fertilizer is applied to eggplant, which will affect the absorption of calcium in eggplant, resulting in longitudinal sepal cracking and cork phenomenon in eggplant, and excessive nitrogen fertilizer will affect water absorption, resulting in the top of eggplant fruit depression and hardening. Therefore, we need to use nitrogen fertilizer rationally to prevent this from happening.

2: If excessive phosphorus fertilizer is applied. Excess phosphorus will be deposited in the soil, which will cause soil compaction, which is not conducive to the growth and development of plant roots.

Moreover, after the excess of phosphorus, it will also affect the growth of the plant, resulting in many side branches and dark green leaves. For example, too much phosphorus fertilizer is applied to tomatoes, and the relative nitrogen, potassium, and various elements will be reduced, which will lead to stunted development of tomatoes and affect the yield of tomatoes.

Therefore, we must reasonably control the use of phosphate fertilizers, and cannot overuse phosphate fertilizers and other fertilizers.

3: If potassium fertilizer is applied excessively. The excessive use of potassium fertilizer first causes a significant increase in the concentration of soil solution, which will lead to secondary salinization, that is, a large increase in the salt content in the soil, which will affect the normal growth and development of vegetable roots.

If the root system of vegetables grows poorly, it will affect the healthy development and growth of vegetable plants, which will greatly reduce the disease resistance and stress resistance of plants. Therefore, we should pay attention to the rational use of fertilizers such as potash.

Extended information: Simple treatment of fertilizer overuse: if the symptoms are mild and have little impact on the plant, no special treatment can be required; If it is severe, you should pay special attention to it, you can water it several times to dilute the excess fertilizer.
