含氨基酸水溶肥料对淮麦22产量·生物学性状和经济效益的影响

目的]研究含氨基酸水溶肥料对淮麦22产量、主要生物学性状和经济效益的影响。方法]以淮麦22为试验材料,在孕穗期、灌浆期施用3个处理的肥料(处理1,常规施肥+375 m L/hm~2含氨基酸水溶肥料+300 kg/hm~2清水;处理2,常规施肥+300 kg/hm~2清水;处理3,常规施肥+叶面不喷任何液体),研究不同处理对淮麦22产量、主要生物学性状和经济效益的影响。结果]与处理2、3相比,处理1能够延长叶片的功能期,促进籽粒灌浆,从而增加千粒重,提高小麦产量,增加经济效益。结论]施用含氨基酸水溶肥料增产效果明显,适宜大面积示范推广。

Effects of Water-soluble Fertilizers Containing Amino-acids on the Yield,Biological Characters and Economic Benefits of Huaimai 22

Objective] To research the effects of water-soluble fertilizers containing amino-acids on the yield, major biological characters and economic benefits of Huaimai 22.Method] With Huaimai 22 as the test material, fertilizers of three treatments were applied in booting stage and grain filling stage.Among them, treatment 1 was conventional fertilization+375 mL/hm2 water-soluble fertilizers containing amino-acids+300 kg/hm2 clean water;treatment 2 was conventional fertilization+300 kg/hm2 clean water;and treatment 3 was conventional fertilization+spraying no liquid on the leaves.Effects of three treatments on the yield, major biological characters and economic benefits of Huaimai 22 were researched.Result] Compared with treatments 2 and 3, treatment 1 extended the functional period of leaves, promoted the grain filling, enhanced 1 000-grain weight and yield, and increased economic benefits. Conclusion] Application of water-soluble fertilizers containing ami-no-acids shows obvious yield-increasing effects, and is suitable for the large-area demonstration and extension.
