控失肥对小麦生物学性状及产量的影响

Effects of Loss-control Fertilizer on Biological Character and Grain Yield of Wheat

[目的]研究不同施肥处理对小麦生物学性状及产量的影响,探讨控失肥对小麦的增产效果。[方法]实施小麦施用控失肥肥效田间试验。[结果]控失肥处理小麦有效穗数、实粒数、结实率、千粒重和产量分别比常规施肥处理高34.2万穗/hm2、0.32粒、3.77%0、.19 g和447.52 kg/hm2。[结论]控失肥能够增加小麦群体的有效穗数、实粒数,提高结实率和千粒重,增产效果明显。

[Objective] The influence of different fertilizing treatments on the wheat biological character was investigated. And the effect of the loss-control fertilizer on wheat yield was discussed. [ Method] Loss-control fertilizer field experiment was conducted. [ Result] The effective spike number of wheat, real grain number, maturing rate, 1 000-grain weight and grain yield treated with loss-control fertilizer increased 34.2 ten thousand spike/hm^2, 0.32 grain,3.77% ,0.19 g and 43,7.52 kg/hm^2 compared with normal fertilizer. [Conclusion] Loss-control fertilizer enhanced effective spike number of wheat, real grain number, maturing rate, 1 000-grain weight and grain yield, The stimulation effect was obvious.
