Abstract
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.关键词
