【摘要】 沟播小麦的单株叶面积大,群体叶面积系数下降速度慢,叶绿素含量增加,单株干物质生产力高于平作畦麦,具有个体壮、后期群体强的干物质生产特性,套作优势值大。60 cm沟播小麦能兼顾高产和利于套作,且周年产量最高,是沟播小麦最有利的种植方式。更多还原

【Abstract】 The furrow-drilling wheat could increase the leaf area per plant,chlorophyll content,dry matter content per plant and RIS,and slow down the descending speed of leaf area index of the population.Strong plants and high population productivity of dry matter at later stages were the main biological reasons.60 cm furrow-drilling wheat could achieve high yield and facilitate intercropping,which was considered as the most favorable furrow-drilling cultivation mode.更多还原
