山西雨养小麦地膜栽培增产潜力与提升途径探讨

Yield Improving Potentiality and Improvemental Ways for Plastic Mulching Rainfed Wheat in Shanxi

山西省雨养小麦地膜栽培起步早,具有独创性,增产效果明显,技术创新多,但比较效益低限制了该技术的发展。小麦地膜栽培面积仅占可播种面积的9.63%,挖掘潜力首先是扩大栽培面积。从高产典型、年降雨量、光温气候、品种、技术方面对山西省冬小麦地膜栽培的增产潜力进行分析,提出了实现增产的有效途径。

Rainfed winter wheat plastic mulching cultivation is pioneer in Shanxi, with innovative and increased yield effect and lots innovative techniques, but low comparative efficiency limited its development. Plastic mulching acreage accounts for only 9.63% of total wheat cultivation area. Increase potential of plastic mulching wheat was analysed basing on the typical high-yielding cases, annual pre- cipitation, climate, wheat varieties, and techniques in Shanxi. We put forward suggestions to improve yield.
