The effect of applying N-fertilizer or not in wheat on soil fertility and grain yield and fertilizer-N use efficiency (FNUE) of rice in the wheat-rice cropping system were studied.
通过对前茬作物小麦设置施用氮肥与不施用氮肥处理研究它对土壤肥力及后茬作物水稻产量和氮肥利用率的影响。
The results showed that the efficiency of fertilizer N used by wheat increased and a higher percentage of N absorbed was translocated into grain under the interplanting condition.
结果表明，麦棉套作条件下，小麦对肥料氮的吸收和利用率显著提高，且所吸收的氮素较多地分配到籽粒中。
Then the efficiency of nutrient was significantly increased by controlling N and saving P fertilizer.
控氮节磷施肥均能明显提高水稻养分利用率。
