长期以来,随着化肥的大量使用,我国的农产品产量大幅度提高,但随之也出现不少问题,如土壤板结,土壤有机质含量下降,土壤微生态平衡失调,甚至有些地区出现土壤环境污染等现象。因此,如何才能既使作物增产又不破坏土壤环境,从而发展可持续农业,已成为亟待解决的问题。从世界范围看,肥料的研制与发展正朝着高效复合化、生物活性化和无公害化方向发展,我国在这些方面也做了大量工作,并取得了一定成绩,其中一个重要的方面就是腐 For a long time, with the extensive use of chemical fertilizers, the output of agricultural products in our country has been greatly increased. However, many problems have emerged such as soil compaction, soil organic matter content decline, imbalance of soil microbial ecology, and even soil environmental pollution in some areas phenomenon. Therefore, how to increase the output of crops without damaging the soil environment to develop sustainable agriculture has become an urgent problem to be solved. From the perspective of the world, the research and development of fertilizers are moving towards efficient compounding, bioactivation and pollution-free development. Our country has also done a great deal of work in these fields and has achieved certain achievements. One of the important aspects of this is rot
