In many places, burned straw is buried. What are the advantages and disadvantages?

In the WeChat circle of friends, the most talked about recently is straw burning, government notice, blue sky ban, discussion and opinions of farmers' friends, and more silence. Talking about straw burning from a personal point of view, a sentence prohibiting straw burning makes farmers cry. The expert group suggested that incineration should be linked to environmental pollution. Many farmer friends, especially contractors, don't understand! So, is burning straw good or bad is better than good? Reduce the occurrence of pests and diseases. Many germs and eggs are parasitic on straw. Burning can kill germs and eggs stored in straw. This method is the most effective and the lowest cost.

Reduce the number of weeds. Most weeds in Chinese medicine hospitals fall on the surface of cultivated land after maturity, and burning straw can clean up most grass seeds. In addition to the weeds with stems as the breeding object, the number of weeds in the field can be reduced in the next season. Collect compost and return it to the field. The ash from straw burning contains a lot of potassium and phosphorus, which can be absorbed by soil and crops without decomposition and can be directly applied to soil. Increase soil permeability. Through the high temperature of straw burning, the topsoil is heated and expanded, which improves the physical properties of topsoil and improves the permeability of soil. In the past, the level of breeding was underdeveloped, and most cultivated varieties were fat varieties, with low yield and low density. In the past, farmers used straw as fuel and livestock feed, which could only burn endless straw. In other words, the amount of straw burning is very small.

It is no exaggeration to say that agricultural machinery has no interference in farming. Most of them rely on human or animal power to cultivate, but the efficiency is limited, and the cultivated land is far less than it is now. There are not as many people burning straw as now. In winter, the temperature is low and the time is long, and the straw is not easy to rot, which affects the normal agricultural production. Regarding the benefits of returning straw to the field, I want to say that it took those experts two years to know the pros and cons. Since incineration is not allowed, straw treatment must be put on the agenda. The efficiency of expensive electricity, fato and binding is lower than that of incineration, which easily affects the cultivation time of the next crop. Straw should be crushed, residual roots should be deeply turned, and urea should be added to promote rapid corruption and increase production costs. It costs money to tie it up or pack it and send it to other places, but no matter how to deal with it, it seems that not burning it will always increase the cost.

The harm of burning straw will pollute the air, it is difficult to control the fire, affect the traffic and threaten the safety of people's lives and property, especially burning straw near the village. The consequences of the fire are unimaginable, but more of a safety issue. For the beautiful scenery of my hometown, it seems an inevitable choice to ban burning straw in the open air. It is unnecessary to plow, burn wasteland and pile fertilizer, how can it become pollution! Has the organic matter returned to the soil? We should proceed from reality and fundamentally solve the problem. The government put forward the methods to solve the problem, how to deal with the straw and how to recycle it. How much is the subsidy for a catty or an acre of land? The state should guide farmers to use straw, so as to increase the pressure on farmers, instead of treating straw improperly across the board.
