| 摘 要： | 目的]研究烤烟节水灌溉条件下水、钾、EM耦合效应。方法]以烤烟为研究对象,采用桶栽试验,研究了水、钾、微生物EM 3因素4水平对烤烟种植的影响。结果]水、钾、有效微生物EM的增加均能增加烟叶产量,但水的影响极显著;对烟叶总氮含量影响大小分别是水、钾、EM;上、中、下3部位叶片中的钾平均含量分别为4.50%、5.01%、6.20%;在一定范围内EM的施用能增加烟叶中的钾含量。结论]3因素联合使用较任一因素单独使用能产生节水、节肥、增产的目的。

| Abstract: | Objective] The aim was to study coupling effect of water,potassium and EM on tobacco under water-saving irrigation.Method]Through barrel experiment,the coupling effect of water,potassium and EM with their four levels on tobacco was investigated.Result] The results revealed that only water had an extremly impact on tobacco's yield,altough others all had positive effects;water had more influence on tobacco's nitrogen content,while EM had less influence on this field;the potassium content in up-leave,middle... |
