In agricultural production, crop straw treatment has always been a problem, before the time these straw are burning, in fact, burning for the soil and farmers are the most economical and convenient, straw burning after the direct into organic fertilizer, do not need time to ferment, the year can increase the fertility of the soil, and in the process of burning, but also can kill some of the eggs and germs, kill two birds with one stone, but this method of safety is relatively poor, polluting the environment has been prohibited, then there are other ways to deal with straw?
Now the mainstream is straw crushing, corn or wheat straw is crushed at harvest time, straw crushing will not be fermented immediately after crushing, and the temperature will affect the time of straw fermentation. Fermentation will be faster in the summer and slower in the winter. The land cultivated all year round will more or less leave some straw that is difficult to ferment, and the biggest impact of these straws will cause the seeds to be exposed to the air, affecting the germination rate of the seeds. In order to shorten the time of straw fermentation, 3-5 kg of urea can be applied per acre.
Some land is not suitable for perennial straw crushing, some farmers will directly collect the straw and pull it away, and some villages will establish a straw storage area, and finally will pull it away centrally. However, there are also some places where straw is littered everywhere, especially in some drainage ditches.
Recently, some advanced harvesting machines have emerged, and the straw is directly packed while harvesting crops, and finally centralized processing. However, this situation is also adapted to local conditions, and the crops in most areas are mainly retail households, and they are not suitable for this large machine for harvesting and packing.
In fact, the main problem in this situation is how to deal with straw and develop new uses for straw, so as to eliminate burning and fundamentally solve the phenomenon of straw littering.
