There is a saying in the countryside: "A crop of flowers, all rely on fat to become a master." The “fertilizer†here refers to the farmyard manure, which is a fertilizer that is mainly processed by human waste. It is said to be organic fertilizer with fashionable words. In the past, some people used to graze a manure basket and smashed the manure. But nowadays, with the widespread use of chemical fertilizers, the original "home fat" has become useless garbage piled up everywhere and harms the environment. The "home" status has been replaced by chemical fertilizers. Why is the farmer's fertilizer not in the scenery? Should farmyard fertilizer really withdraw from the fertilizer stage?
It is understood that there are many reasons for forcing farmer's fertilizer to “lay offâ€; one is the good tradition of building farmyard manure, the lower level emphasizes less, the middle is less, and the farmers use less. Second, the farmers have misunderstandings about the use of chemical fertilizers. They believe that chemical fertilizers are effective, as long as more fertilization can increase production, and the understanding of the harm of chemical fertilizers is insufficient. Therefore, the use of chemical fertilizers is very dependent and dependent. Third, at present, a large number of young and strong young people in rural areas have been transferred from agriculture, and there is no energy to accumulate farmer's family fat. Fourth, today's farmers like to plant "health fields", fearing that human and animal waste will be dirty, preferring to spend money to buy fertilizer instead of being affected by the soil.
In fact, fertilizer also has its own "soft ribs." The problems and side effects of its use can not be underestimated. First of all, the waste of chemical fertilizers is amazing. The soils vary widely, and the crops have their own characteristics. The right amount of fertilizer is balanced under the right amount, so that the best effect of the fertilizer can be exerted. In actual production, farmers often rely on experience to estimate, blind fertilization, excessive fertilization, it is difficult to balance the symptomatic fertilization, resulting in low fertilizer utilization, resulting in huge waste of fertilizer. According to estimates, the effective utilization rate of chemical fertilizers in China is only 35%, and 65% is wasted. Second, long-term excessive use of chemical fertilizers will seriously damage the rural ecological environment.
The use of farmyard manure can turn rural manure and livestock waste into treasure, purify the environment, reduce the cost of planting land, and increase farmers' income. Long-term use of farmyard manure can not only improve soil properties, but also has a significant effect on increasing crop yield and improving crop quality, and is an ideal fertilizer for developing ecological agriculture.
In order to re-establish the farmer's fertilizer, it is necessary to widely publicize, guide and mobilize the farmers to calculate the benefit account, calculate the savings, and spread the farmer's fertilizer. It is necessary to include the use of farmyard manure as an important part of the construction of a conservation-oriented society, encourage farmers to return fertilizer to the fields, cultivate soil fertility, improve soil, and achieve a virtuous circle of land cultivation. The agricultural technology department should vigorously promote soil testing and formula fertilization, and prescribe “prescription†on land conditions, guide farmers to use scientific fertilizers, make fertilizers and farmyard fertilizers complement each other, complement each other and improve the utilization rate of fertilizers.
