壮丰安对大豆增产效应的研究

Studies on the Effect of Zhuangfengan on Soybean Yield

在不同土壤肥力、不同种植密度的条件下 ,大豆花期叶面喷施壮丰安 (1∶5 0 0 )的试验结果表明 :壮丰安可明显降低株高 ,茎第 4～ 11节间明显缩短 1.7～ 3.5cm ;茎增粗 ,叶片增厚变小 ;并提高单株荚数和粒茎比 ,平均较对照增产 2 .8%～ 2 2 .1%。

Zhuangfengan was used by foliar spray during the flowering phase of soybean in different fertility of soil and different planting density, the results showed: Plant height reduced,stem foot was strong, leaves became small and thick, effective branch increased.sometimes number of pods per plant and kernel/stem increased.Yield 2.8%～22.1% was increased.
