10年肥料长期定位试验结果表明,化学氮肥配施有机肥处理对冬小麦的增产效果最好,比对照处理减少变异系数14.95%;氮磷钾化肥配施处理增产效果次之,减少变异系数13.73%;单施化肥处理增产效果最差,减少变异系数3.07%.夏玉米产量受气候影响波动比冬小麦大,化学氮肥配施有机肥处理减少变异系数25.61%,增产效果最好,氮磷钾化肥配施处理减少变异系数19.21%,增产效果次之;单施有机肥处理减少变异系数8.08～12.31%,增产效果比单施化肥处理的还差.
The results of long-term fertilization experiments for 10 years showed that the chemical fertilizer application with chemical nitrogen fertilizer had the best stimulation effect on winter wheat yield and the coefficient of variation was 14.95% less than the control treatment. The NPK fertilizer treatment was the second to reduce the coefficient of variation by 13.73% ; Single application of chemical fertilizer treatment yield the worst, reducing the coefficient of variation 3.07% .Small maize production by climate fluctuations than winter wheat, chemical fertilizer with organic fertilizer treatment to reduce the coefficient of variation of 25.61%, the best yield, nitrogen, phosphorus and potassium fertilizer with The treatment reduced the coefficient of variation by 19.21%, followed by the increase of yield. When applying organic manure, the coefficient of variation was reduced by 8.08-12.31%, and the yield increase was worse than that of chemical fertilizer alone.
