摘要:
旱地麦田二次覆盖增产模式比常规耕作土壤含水量提高1.97个百分点以上.有机质增加0.2个百分点,速效磷增加17mg/kg,速效钾增加25mg/kg,速效氮增加11.5mg/kg,光合速率提高9.2mgCO2/(dm2·h).
Abstract:
Compared to conventional tillage under the mechanism of the second straw mulching of dryland wheat,soil water content increased 1.97 percent point,organic matter content 0.2 percent point,a vailable phosphate 17mg/kg,available potassium 25mg/kg,available nitrogen 11.5mg/kg,and photosvnthetic efficiency 9.2mgCO2/(dm2·h).
