杨-粮间作新栽培模式对小麦产量及质量影响的评价

The Impacts of New Cultivation Patterns of Incorporating Poplar with Wheat on Wheat Yield and Quality

主要探讨了杨－粮间作新栽培模式对小麦产量和质量的影响。研究结果表明：５年生杨树杨－粮间作新栽培模式［（３×３）ｍ×２０ｍ，（３×３）ｍ×３０ｍ，（３×３）ｍ×４０ｍ］小麦产量低于对照农田１０％～１５％、；林内小麦种子的淀粉含量和蛋白质含量均高于对照农田，分别增加了１２％和２２．１％，蛋白质提高幅度大于淀粉提高幅度。影响小麦产量和千粒重的主要因子为照度、空气温度、空气湿度及土壤含水量；提高小麦质量的主要因子为空气温度。

This paper deals with the impacts of new cultivation patterns of incorporating poplar with wheat on its yield and quality. The result shows that the yield of wheat in the new cultivation patterns is reduced by 10%～15% than that in the mono crop field at the 5th year since poplar trees were incorporated [the cultivation model are (3×3) m×20 m,(3×3) m×30 m,(3×3) m×40 m]; the content of starch and protein in the wheat′s seed is increased by an average of 12% and 22.1% respectively,compared with the mono crop field,the range of the increasing protein content is greater than that of the increasing starch content; the major factors affecting the yield of wheat and thousand grain weight are illuminance,air temperature,air moisture and soil water content; the major factor of increasing wheat seed quality is air temperature.
