摘  要:
以不施氮肥、尿素基施和尿素基追比5:5等3个处理做对照,对3种包膜缓/控释肥处理冬小麦产量、产量相关因子、不同时期植株含氮量及肥料利用率进行了分析比较。结果表明,缓/控肥处理的以上几个指标均接近于尿素基追比5:5处理。与尿素基施相比,包膜缓/控释肥增产10.03%~11.17%,有效穗数和穗粒数增加,返青-拔节期植株含氮量明显提高,氮肥利用率提高了6.18%~11.57%。3种缓/控释肥相比较,产量、产量因子、植株含氮量及肥料利用率没有显著性差异。

摘  要:
Grain yield,yield composition factors,nitrogen content in wheat and fertilizer-nitrogen use efficiency of three different slow/controlled release fertilizers(SCRF) were investigated.We used no nitrogen fertilizer treatment as the control(CK1) and the other treatments include all urea application as basal(CK2) and urea application in 5:5(basal to top dress t,CK3).The results were as follows: Compared with CK2 the grain yields of SCRFs was increased by 10.03%-11.17% due to increase in the effective ear and grains per ear;The nitrogen content in the plant treated with three SCRFs were higher than CK2;and the use efficiency of fertilizer-nitrogen was 6.18-11.57% higher than that of CK2.
