“粮豆轮作”对化肥施用量的影响研究

Study on the Effect of“Grain and Bean Rotation”on Fertilizer Application Rate

由于我国化肥的滥用,导致农业生产成本越来越高,不仅不能提高产量,还破坏土壤结构,降低土地肥力,抑制了粮食产业的发展,阻碍农业的绿色可持续发展。通过对已有的文献进行综述,得出以下结论,“粮豆轮作”可以减少化肥施用量、降低农业生产成本,对我国农业实现绿色可持续发展有重要意义,对改善化肥滥用现象和相关农业政策的制定有指导意义。

Due to the abuse of chemical fertilizer in China,the cost of agricultural production is becoming higher and higher.It can not only fail to improve the yield,but also destroy the soil structure,reduce the fertility of the land,inhibit the development of the grain industry,and hinder the green and sustainable development of agriculture.Based on a review of the existing literature,this paper drew the following conclusions,“grain and bean rotation”can reduce the amount of chemical fertilizer and reduce the cost of agricultural production,which is of great significance to the realization of green and sustainable development of agriculture in China,and has a guiding significance to improve the abuse of chemical fertilizer and the formulation of related agricultural policies.
