摘  要：
采用长期定位培肥试验的方法,较系统地分析了长期单施有机肥、单施化肥、有机肥与化肥配施条件下,作物产量动态变化。结果表明:在一定的年限内,氮磷化肥配施有机肥或单施有机肥能持续稳定增加作物产量;长期单施氮磷化肥,在产量水平较低的情况下能快速提高作物产量,当达到一定水平后作物产量则在徘徊中缓慢增长。氮磷化肥配施有机肥具有持续提高产量、培肥土壤的双重效果,是砂姜黑土培肥改良较理想的施肥方式,但同时要注意钾素的补充。

摘  要：
A long-term fertilizer trail was conducted to study dynamic changes of crop yield and soil nutrient content.The result shows:On the Service life of different,long-term use of single organic manures,nitrogen phosphorus chemical fertilizer and organic manures cooperation fertilizer,can obviously increase the output of crops continually and steadily;Long-term the nitrogen phosphorus chemical fertilizer,can improve crops yield fast in a situation that the output level is lower,the crop yield increases slowly while wandering up and down after reaching certain level,can improve available nitrogen,total phosphorus,content of available phosphorus,and organic matter,total nitrogen increase limited.Nitrogen phosphorus chemical fertilizer combined organic improve yield,more ideal way of fertilizing.But should pay attention to the plain supplement of potassium at the same time.
