If farmers do not use chemical fertilizers and pesticides in farming, can they really increase yield

Responsibility alone cannot increase yields, and fertilizers and pharmaceuticals are needed to increase yields. <> it's even worse if farmers don't use pesticides in their farming. With the development of agriculture, various pests of crops are increasing year by year, so there are more and more pests.

If pesticides are not used in time to kill, due to the strong reproductive ability and fast growth rate of pests, pests are easy to flood, resulting in a large area of crop yield, and some even no harvest. No matter how responsible farmers are, they are unable to control the spread of this serious pest. They must use pesticides to kill the larvae in time to control the pests and obtain high yields of crops.

Therefore, if farmers do not use chemical fertilizers and pesticides, they will not be able to increase their yields by being responsible alone. Only by using chemical fertilizers and farm fertilizers rationally can crops absorb the nutrients they need to grow in a timely manner. As long as we manage scientifically, water in a timely manner, and prevent and control pests and diseases, we can greatly increase the output and the income of farmers.

Since the advent of chemical fertilizers, farmers basically do not need farm fertilizer for farming, and farmers do not pay attention to or apply fertilizer scientifically, even regardless of the cost. The yield is increasing year by year, but the cost of production is also increasing year by year, and the soil fertility is also finished. Fortunately, the Ministry of Agriculture and Rural Affairs has vigorously advocated green planting and environmentally friendly planting, and has achieved zero growth in the use of chemical fertilizers for four consecutive years.

The state has also implemented high-standard farmland construction to cultivate soil fertility, achieve sustainable development, and greatly improve soil organic matter. <>

At present, the quality of peasants is also improving, soil testing and formula fertilization are applied, and grain output is also steadily increasing. But now no one wants to use organic fertilizer, the cost of pharmaceutical organic fertilizer is very high, and it also needs to be decomposed and fermented before it can be used, which is very troublesome. Therefore, farmers cannot increase their yields without chemical fertilizers and pesticides.

No, because if you don't use chemical fertilizers and pesticides, you can cause pests and diseases, and crops can't thrive, so you can't increase yields.

I don't think it's possible to increase yields, because without the use of chemical fertilizers and fertilizers, the nutrients in the soil alone will not be able to meet the nutrients needed for plant growth

At present, in the process of agricultural planting, it is still necessary to rely on chemical fertilizers and pesticides. Especially in large-scale agricultural production, this is the most basic to ensure yield.

Without the use of chemical fertilizers, it is necessary to weed and plow the crops in time and water them on time to increase yields.

The sense of responsibility alone can not completely improve the yield of crops, but also can not use chemical fertilizers and pesticides indiscriminately, to learn scientific and reasonable planting methods, which is the key to improving yield.

Personally, I think it's very difficult, because if you want to increase the yield of crops, you have to apply fertilizer, pesticides, and watering, otherwise the yield is very low.

No, it is necessary to fertilize the field regularly and ensure the fertility of the soil in order to increase the yield of crops.

I think it is difficult to increase yields, and if pesticides are not used, they may lead to pests and diseases, and in the face of such a situation, if you only do a good job of field management, you will not be able to completely remove pests and diseases, and you will not be able to guarantee the yield.

If you want to increase the yield, it is still necessary, and if you don't use fertilizer, then I think you need to use animal manure.

We must choose organic soil and work, the density of planting must not be too dense, we must pay attention to proper ventilation, and we must choose excellent varieties.

Fertilizers can be organic fertilizers, and pests can be biocidal.

For example, some intercrops can repel insects.

Or use plant pesticides, if you don't understand, you can go to farming nets.

We should promote scientific and technological planting, study some new scientific and technological planting methods, and ask relevant technical personnel to help and support in the degree of planting, strictly control and plant in accordance with scientific methods.

If chemical fertilizers are not used in agricultural production, farm manure and some grass compost alone will be far from satisfying the fertilizer needs of crops. Farmhouse manure and its well-decomposed fertilizer can play a better role in improving the soil, but its nitrogen content and various elements required by crops are insufficient, and can not meet the needs of crops in time. As a result, the crop cannot absorb the elements needed for growth in time, so the growth is slow, the leaves are yellow, and the plants and rods are short.

The hair rod is slow and the sin is too little, which seriously affects the normal growth of crops. Resulting in severe crop losses. The nutrients and elements needed for the growth of crops cannot be improved by a strong sense of responsibility on the part of the farmer alone.

<> it's even worse if farmers don't use pesticides in their farming. With the development of agriculture, various pests of crops multiply year by year, so there are more and more pests. If pesticides are not used in time to kill, due to the strong reproductive ability of pests and fast growth and development, pests are easy to flood, resulting in a large area of crop yield, and some even no harvest.

No matter how responsible farmers are, they are unable to control the spread of this serious pest. They must use pesticides in time to kill the larvae in order to control the pest and obtain high yields of crops.

Therefore, if farmers do not use fertilizers and pesticides, they will not be able to increase yields with responsibility alone. Only by using chemical fertilizers and farm fertilizers rationally can crops absorb the nutrients needed for growth in a timely manner, so that crops can grow luxuriantly. It is also necessary to kill insects in time to prevent the spread of insect pests.

Maximize crop yields. At present, agricultural planting does not rely on science and technology, but only on intensive cultivation, and there is not much room for advocating high yield and sweat. As long as scientific management, timely watering, and prevention of pests and diseases, chemical fertilizers and pesticides can greatly increase production and income.

Do a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

First, protect the soil, regularly loosen the soil, weed. Second, water and fertilize the farmland regularly. Third, for the selection of seeds for planting crops, it is necessary to choose excellent varieties.

It is necessary to choose a good field, maintain the environmental hygiene of the field, weed in time, ensure sufficient light and moisture, and drain water in time after rain.

First of all, we must choose varieties with strong resistance to diseases and pests, and secondly, we must do a good job of drainage to ensure that the plants get enough light.

<> based on my decades of farming experience, it is not enough to rely on a sense of responsibility to improve the production of farming. It is necessary to have excellent varieties, sufficient fertilizers, timely prevention and control of pests and diseases, and reasonable irrigation.

Phasing out chemical fertilizers and pesticides of agricultural products, the heart must be ruthless, the pace must be steady, and the gradual push will not waver, and the first and agricultural product producers at all levels will sign contracts and progress at all. For those who perform well, reward: for those who violate the yang and yin, they will be punished!

The face of the punishment has been pondered. For relevant production enterprises, encourage and support the green transformation and upgrading of products, and the production of harmless organic fertilizers.

In order to increase yield, it is necessary to select excellent varieties for planting according to the actual conditions of local soil quality, geography, water resources, etc. 2. Fertilizer. As the saying goes, a crop depends on fertilizer.

With good varieties, there must also be sufficient fertilizer. Grow crops in a small area, and if you raise a lot of livestock and poultry, you can use fermented livestock manure without chemical fertilizers. However, the effect time of agricultural machinery fertilizer is short, and it must be fertilized many times in the whole growth stage of crops, which is more difficult.

Crop pests and diseases, judging from the current situation, are not very optimistic in terms of area or frequency. The use of pesticides to control pests and diseases is a very practical method and a necessary means to ensure a good harvest of crops. Reasonable irrigation.

Food crops, especially rice, have a great need for water, so farmers always hope for good weather.

It is not every year that the weather is good, or there are droughts or floods, and the crops grown by farmers are also affected as a result. This requires proper irrigation and drainage to minimize damage to crops. In short, in order to increase grain output, it is not enough to rely on a sense of responsibility alone, but also to have excellent varieties, sufficient fertilizers, timely prevention and control of pests and diseases, rational drainage and irrigation, and scientific management.

Take green ecological organic agriculture without chemical fertilizers and pesticides as an example, we can learn from Israel, the country they established in the desert, realized the self-sufficiency of green ecological agriculture in food, vegetables and exports, and its advanced agricultural technology, such as greenhouse vegetable planting technology and drip irrigation water-saving technology, were given to our country as a thank you gift free of charge.

First, you can water the crops in an appropriate amount to allow them to fully absorb nutrients; second, it can be weededed, which can reduce weeds and crops competing for nutrients; Thirdly, it can loosen the soil and maintain a fertile environment.

The use of organic fertilizers does not increase the yield of rice without using any chemical fertilizers and pesticides. No pesticides are used in the cultivation of rice, wheat, etc., so it may lead to crop failure, even if the grain is harvested, all kinds of risks are greater, if there is no prevention and ** wheat, for example, 3-wheat vomitoxin will cause harm to the human body, if it is violated on rice during the rice disease without the use of pesticides, in this rainy weather, the possibility of rice smut is very high, and rice smut will also produce aspergilloin, which is much more toxic than pesticides.

The demand for nutrients in fertilizers is different in different years, some years need more nitrogen, phosphorus and potassium, and some years need less nitrogen, phosphorus and potassium, and potassium needs to be supplemented. The supplement of nitrogen, phosphorus and potassium elements can use paclobutrazol and other products to increase production and efficiency. When we do organic fertilizer replacement, the amount of organic fertilizer in one acre of field is generally 2 tons, but different regions are different, so we have to continue to top dress, constantly test the soil formula, and constantly improve.

In this way, maximum yield can be achieved.

Many places in our country are using biofertilizer, we have to understand the needs of farmers at this time, biofertilizer is the fertilizer we want to choose. When we choose a high-quality bio-organic fertilizer, we must choose the most suitable type of organism for growth, and we must have a high organic matter content that can make crops grow well and grow well. These three are related.

If you rely on manual fertilization alone, the efficiency is low, and the cost is high, and the effect will not be very ideal. Our fertilization methods can be sprayed, mixed fertilisers, water-soluble fertilisers, foliar fertilisers, etc. In general, the method of mixed fertilization will be more scientific and the effect will be more ideal.

However, we also need to pay attention to the fact that the mixed fertilizer should not be too much and too concentrated, otherwise, it will affect the effect of the fertilizer. Also, the number of fertilization should also be mastered, generally after 2-3 times can not be fertilized.

If you only use organic fertilizer without using any chemical fertilizers and pesticides, the yield will not increase, because without using pesticides to control insects and weeds, the rice will be destroyed.

It will increase the yield, and there are many nutritious substances in the organic fertilizer, which is good for the plant, so that the plant can have sufficient nutrition and can grow better.

Without the use of any chemical fertilizers and pesticides, the use of organic fertilizer can increase the yield because organic fertilizer can provide nutrients to the rice and make the rice grow stronger.

Growing crops is inseparable from chemical fertilizers, but improper use not only fails to achieve the purpose, but also causes some harm. Therefore, in the process of fertilization, we must fertilize scientifically, and you can eat less potassium fertilizer for food crops, of course, if the potassium fertilizer content is relatively low, you can eat more potassium fertilizer. It is also necessary to ensure that the amount of food used in fertilizer is not too much or less, and it can be applied in batches, otherwise it may also affect the yield of grain.

In the process of eating amperage for crops, you can use deep application of bottom fertilizer or mulching to fertilize, so that crops can absorb enough nutrients, but also to ensure the actual utilization rate of chemical fertilizer, in this process should also be timely chasing water, so as to ensure that the utilization rate of fertilizer can be effectively improved.

Nowadays, many farmers use some fast-acting fertilizers, which generally have a fertilizer effect of two months, but like organic fertilizer, the fertilizer time will be longer. Moreover, there will be different periods in the whole cycle of seed growth to development, and the demand for fertilizer in each period is also different, and the nutrients required for each period are also different, so fertilizer should be applied according to the growth cycle of crops. If the chemical fertilizer needed in the sowing process is used as a base fertilizer at one time, it may damage the root system of the crop, so that the crop can not completely absorb the nutrients, which is a pity and may also cause a certain degree of waste.

In the process of fertilizing crops, many farmers will feel that the closer to the plant root system, the easier it is to absorb the fertilizer, in fact, this fertilization method may cause damage to the root system, and it is very easy to burn seedlings, so the fertilization substance should be determined according to the growth of the plant to ensure the effect of fertilization. Also, don't wait until the crops are completely deficient in fertilizer before fertilizing the crops, which may cause a reduction in yield, so fertilization should be carried out according to the characteristics of the crops.

Finally, the more fertilizer to crops, the better, to ensure scientific fertilization, so that crops can grow according to the normal growth law.
