摘　　要：在青海省高寒旱区,进行了春油菜垄膜沟植技术效应研究。结果表明:垄膜沟植技术对旱区土壤性状及春油菜产量影响效应明显。主要表现在增加土壤含水量,提高水分利用率,降低土壤容重,提高植株生物量和产量。The effects of spring-rape ridge and film trench-planting technology in alpine drought regions of Qinghai Province were studied.The results showed that the ridge and film trench-planting technology had obvious influence on the soil properties and the yield of spring-rape,which could increase the soil moisture,improve the water use efficiency,reduce the soil properties bulk density,and increase the plant biomass and yield.
