化肥的大量投入,使农作物的产量明显提高。化肥明显的增产作用,使农民对化肥产生了很大的依赖性,从而忽视了有机肥的使用。多年来,科学种田水平不断提高,但土壤中的有机质含量有所下降。要想使土地资源永续利用,保证土壤的生产力,必须增施有机肥,提高土壤有机质含量,改善土壤的理化性状,这是保持并提高耕地质量的一条最有效的途径。
A large number of fertilizer inputs, significantly increased the yield of crops. Significant increase of fertilizers, farmers have a great dependence on fertilizers, thus ignoring the use of organic fertilizer. Over the years, the level of scientific farming has been continuously increasing, but the content of organic matter in soil has declined. In order to make the sustainable use of land resources and ensure the productivity of the soil, organic fertilizer must be added to increase soil organic matter content and improve soil physical and chemical properties, which is the most effective way to maintain and improve the quality of cultivated land.
