Returning straw to the field can increase soil organic matter, improve soil structure, loosen soil, increase porosity, reduce capacity, and promote microbial activity and crop root development. Returning straw to the field can significantly increase fertilizer and yield, generally increasing yield by 5 to 10%. However, if the method is improper, it will also lead to an increase in soil bacteria, aggravation of crop diseases, and insufficient seedlings (stiff seedlings). Therefore, only by taking reasonable measures to return straw to the fields can good results be achieved.
Returning straw to fields is a yield-increasing measure to improve soil fertility and has received widespread attention in the world today. It not only eliminates air pollution caused by straw burning, but also increases fertilizer and increases production.
Principle of straw returning to the field:
Straw returning to the field is a method of applying straw (wheat straw, corn straw, rice straw, etc.). ) is not suitable for feeding directly into the soil directly or after decomposition in piles. The process of agricultural production is also a process of energy conversion. During the growth of crops, they need to continuously consume energy, replenish energy, and constantly adjust the content of water, fertilizer, gas, and heat in the soil.
Straw contains a large amount of fresh organic matter, which can be converted into organic matter and available nutrients after a period of decomposition after returning to the field.
