It is another bumper harvest year, and it is the autumn harvest season in Enshi. Our local government has organized many environmental protection inspectors and specially issued relevant documents prohibiting straw burning. It can be seen that the government attaches importance to straw burning. In the past few decades, farmers have used burning to solve problems. But in recent years, urban and rural areas all over the country are engaged in environmental improvement. Under the guidance of the government, farmers' awareness of environmental protection has been continuously improved, and everyone responded to national policies and actively returned straw to the fields. However, through several years of practical operation, farmers in some areas are miserable, crop yield has not been greatly improved, and pests and diseases have become more frequent.

Returning straw to the field was originally beneficial, why is there a bad sequela? 1. Straw is directly crushed and returned to the field. Although this method is simple and quick, it is also the most prone to problems. Straw itself will have some pests and diseases. If it is simply crushed and returned to the field, the source of pests and diseases carried by straw will naturally stay in the field, which will have a great impact on the next crop.

2, straw treatment technology is not in place, to be honest, many farmers still have a little knowledge about returning straw to the field, and they simply don't know how to make better use of it, which leads to the straw can't be fully decomposed, and it is easy to cause problems such as root burning, pests and diseases of the next crop.

So what do you need to pay attention to when returning straw to the field? 1. For the straw returned directly to the field, it must be disinfected to effectively avoid the high incidence of pests and diseases. Tubak 1 is generally recommended for wheat fields, and carbendazim and quicklime are recommended for corn fields.

2. Rolling in time. When the straw contains a lot of water, crush it, and don't wait for it to dry. Sufficient moisture in straw is beneficial to the rapid fermentation of straw, reducing nutrient loss and improving the utilization rate of straw. Therefore, we should crush orange stalks as soon as possible after harvest.

3, timely decomposition or ploughing into the soil, full decomposition is the basis of effective utilization, no matter what method is adopted, it must be fully decomposed, so as to reduce the risk in the later stage.

4. Crushing with the harvest ensures that the nutrients in the straw are not lost, and the moisture is sufficient, which is more conducive to fermentation. Generally speaking, for plain areas, mechanical harvesting and crushing can be used to return to the field. For farmland in mountainous areas, we can only harvest it first and then concentrate on crushing it.

So what are we going to do with these straws? There are actually many good methods for straw treatment. Around the area where the snow geese are located, there are probably three methods:

1, the combination of planting and breeding, straw as feed for livestock, so that it can be used efficiently, this method is a practical method for small-scale planting. Brother Xueyan's village uses a lot. Corn stalks are directly taken to the cattle farm, which is easier to ferment and decompose after being eaten and digested by cattle, and becomes a good farm manure. However, this method is only suitable for small-scale planting and large-scale planting, and the recovery and crushing of straw requires a lot of manpower, which is very impractical.

2. Composting is mainly in the form of crushing straw, then spraying livestock manure and a small amount of urea, and covering it with film after pouring thoroughly, which can accelerate the decomposition of straw. After a few months, the orange stalks will be decomposed into organic fertilizer.

The quickest and most effective way is actually to return the straw directly to the field. Different from before, the straw is disinfected with a professional disinfectant (generally carbendazim) as soon as it is crushed, and then directly mixed with the ploughed soil, which is beneficial to the rapid fermentation of the straw.

4. It is the most scientific, environmentally friendly and efficient way to directly let the producers of organic fertilizer recycle straw, smash and ferment to produce organic fertilizer and then return it to the field. At present, there is such a factory in Xueyangou, which recycles the orange stalks of surrounding crops, then processes them into high-efficiency organic fertilizers and sells them to farmers. Although this method is good, it takes a lot of manpower and material resources to recycle orange stalks, and farmers are not willing to toss.

In short, in my opinion, returning straw to the field can save resources on the one hand and increase investment on the other. Therefore, more attention should be paid to straw returning to the field, and straw should be disinfected and fully decomposed before use.
