摘要
在大豆始花期、盛花期和结荚期对黑农58品种群体叶片喷施金克拉全营养生态肥,探讨其对大豆产量的影响。结果表明：在始花期-结荚期喷施金克拉可提高黑农58品种群体单叶PSⅡ活力和光合速率及光饱和点;喷施金克拉后黑农58品种单株重和单株粒重比CK分别提高17%和18%,其差异达到显著水平。
Jinkela multi-nutrition fertilizer was sprayed on leaf of Heinong 58 at R1,R3,R5,respectively,and the effect on yield was discussed.The result showed that PSⅡ activity,photosynthetic rate and LSP of single leaf of Heinong 58 were increased after sprayed Jinkela from R1 to R5;single plant weight and single plant seed weight of Heinong58 were improved 17% and 18% than CK respectively and evidently.
