喷洒有效微生物群(EM)对小麦旗叶衰老和籽粒产量的影响

Effects of Spraying Effective Micro organisms(EM)on Senescence of Flag Leaves and Grain Yield of Spring Wheat

小麦植株喷洒有效微生物群制剂（ＥＭ），显著提高了旗叶衰老期间的光合作用速率和叶片可溶性蛋白质及叶绿素含量，降低了叶片细胞膜脂过氧化作用，提高了籽粒生长速率并显著增加了籽粒产量。

Spraying EM upon wheat plants(cv.Liaochun10)increased photisynthtic rate and soluble protein content as well as chlorophyll content significantly,and inhibited membrane peroxidation in some extent of flag leaves during senescence after anthesis,which raised kernel growth rate and enthance grain yield markedly.
