| 摘 要： | 在化肥减量情况下研究了绿肥翻压量对土壤活性有机质和土壤酶活性的影响。结果表明,当化肥用量降到当地常规施肥量的85%时,翻压绿肥可以明显提高土壤活性有机质含量,但土壤活性有机质的提高量和绿肥翻压量之间没有明显的线性关系。当化肥用量降到常规用量的70%时,翻压绿肥对土壤活性有机质基本没有影响。化肥用量为常规用量85%时,翻压绿肥可以较大幅度提高烟叶旺长期土壤脲酶活性;适当的化肥用量(85%～100%化肥之间)和绿肥翻压量低于22 500kg/hm2时,翻压绿肥可以提高土壤磷酸酶活性。 |

| Abstract: | Effects of burying green manure on tobacco soil labile organic matter and enzyme activity with reduced chemical fertilizer rate were studied.The results showed that green manure improved soil labile organic matter when fertilization reduced to 85% of conventional rate.There was linear relationship among increment of labile organic matter and quantity of green manure.When fertilizer rate reduced to 70% of conventional standard,Green manure had not significant influence on soil labile organic matter.Green man... |
