由于化肥的增产效果显著,曾一度导致农业生产对化肥的过份依赖而忽视了有机肥的施用.但长期偏施化肥造成了土壤肥力减退、环境污染,农业成本增加等一系列问题,近年来有机肥的增产培土作用重新引起人们的关注.本文通过麦稻稻轮作制下不同化肥和有机肥用量的定位试验,研究有机肥的增产效果与持续施用时间的关系,探讨持续施用有机肥对作物的稳产作用,比较有机肥对不同作物的相对重要性。
Due to the obvious effect of increasing production of chemical fertilizers, once led to excessive dependence of agricultural production on chemical fertilizers and ignored the application of organic fertilizers, but a long time partial application of chemical fertilizers caused a series of problems such as soil fertility decline, environmental pollution and agricultural cost increase. In recent years The effect of organic fertilizers on soil fertility and soil-cultivating has aroused people’s attention again.This paper studied the relationship between increasing yield of organic fertilizer and the duration of application by using different fertilizers and organic manure under the rotation system of wheat and rice, and discussed the effects of continuous application of organic manure on crops Stable production, compare the relative importance of organic fertilizer on different crops.
