摘要
我国耕地面积位居全球第三,但是约70%耕地产量不高,大多属于肥力不高的中低产田,农户为了提高种植效益,盲目施用化肥,不仅引发粮食安全问题,还破坏土壤环境,所以环境保护型农业土肥管理技术推广和应用越来越急迫。笔者结合自身工作经验,对农业土肥管理技术在环境保护型农业中的应用现状进行概述,分析和总结了环境保护型农业土肥管理技术的应用技术,从有机肥利用和病虫害防治2个方面提出了促进环境保护型农业土肥管理技术的有效措施。
Chinese cultivated land area ranks the third in the world,but about 70%of the cultivated land yield is not high,most of which belong to low fertility fields.In order to improve the planting efficiency,farmers blindly apply chemical fertilizer,which not only causes food security problems,but also damages the soil environment,so the promotion and application of environmental protection agricultural soil and fertilizer management technology is more and more urgent.Based on the author's own work experience,this paper summarizes the application status of agricultural soil and fertilizer management technology in environmental protection agriculture,analyzes and summarizes the application technology of environmental protection agricultural soil and fertilizer management technology,and puts forward effective measures to promote environmental protection agricultural soil and fertilizer management technology from two aspects of organic fertilizer utilization and pest control.
