Corn is very common in our daily life, and the planting area is also very large. Corn not only has very high nutritional value, but also is welcomed by many people. And after the corn harvest, corn straw can also be used to return to the field as fertilizer, and now it is vigorously promoted by the state. But what are the benefits of returning corn straw to the field? What are the precautions? The following editor will give you a brief introduction, let's have a look!

1. Increase soil nutrients

Corn straw itself actually contains certain nutrients, including basic elements such as nitrogen, phosphorus and potassium, as well as various trace elements. These are the nutrients left over from growing corn. After returning corn straw to the field, these nutrients are effective nutrients for the soil to improve its soil fertility. So returning the corn to the field after harvest, and then planting the next crop, can provide it with some nutrition.

2. Increase soil microbial biomass.

Returning corn straw to the field can not only improve the nutrition level and fertility of the soil. At the same time, it can effectively increase the number of microorganisms in the soil and improve the vitality of microorganisms in the soil. Improve the soil environment and improve the coordination ability of water and fertilizer in the soil. And the increase in the number of microorganisms in the soil is very good for the improvement of the soil. And the retention capacity of soil water and fertilizer will also be enhanced, so it is very good for the growth of the next crop.

3. Improve the ecological environment

Before putting forward the idea of returning corn straw to the field, after each corn harvest, the treatment method of corn straw is mainly burning. Burning corn straw will have a great impact on the ecological environment. The smoke produced by the burning of corn straw not only pollutes the environment, but also is very disadvantageous to human health. Since the corn straw was returned to the field, the level of air pollution has been significantly reduced every year. Therefore, if the corn straw is returned to the field, it can effectively improve the ecological environment and reduce environmental pollution.

4. Points for attention

When we return straw to the field, we should pay attention to the amount of straw returned to the field. Because the acceptable amount of corn straw per mu is limited, it is not possible to return all the straw to the same mu of field. Under certain conditions, an appropriate amount of nitrogen fertilizer can be applied. Because when the soil decomposes the straw, the straw will absorb part of the nitrogen element in the soil, if there is no timely supplement of nitrogen fertilizer, then the next crop may yellowing because of the lack of nitrogen element. Then we should also pay attention to do a good job of watering, which can not only reduce the phenomenon of running wind, but also very beneficial to the decomposition of straw.

The above is a brief introduction to the benefits of returning corn straw to the field. That's all for today's introduction. This article is for reference only. I hope it can help you all.
