摘要:

为轻简化小麦施肥,选用缓释肥料开展符合小麦定额施肥标准下的田间肥效试验。结果表明,施用缓释肥料在减氮20%,总养分投入减少10%~13%时,小麦实割产量增加9.5%~17.0%,主要通过每穗实粒数增加1.0~1.7,或增加单位面积有效穗数、千粒重等小麦产量构成要素来实现;施用缓释肥料能简化小麦施肥并实现增产。

关键词: 小麦, 缓释肥料, 出苗率, 产量

Abstract:

In order to simplify wheat fertilization, slow-release fertilizers were selected to carry out field fertilizer efficiency experiments in line with wheat quota fertilization standards. The results showed that when the nitrogen was reduced by 20% and the total nutrient input was reduced by 10%-13%, the yield of wheat increased by 9.5%-17.0%, which was mainly achieved by increasing the number of grains per panicle by 1.0-1.7, or increasing the effective panicle number per unit area and 1 000-grain weight.

Key words: wheat, slow-release fertilizer, emergence rate, yield
