密度对大豆群体叶面积指数及干物质积累分配的影响OA北大核心CSCDCSTPCD
Effect of Density on Leaf Area Index, Dry Matter Accumulation and Distribution in Soybean Population
在大田条件下,以垦农4号为材料,研究了大豆在5种密度条件下的叶面积指数及干物质积累分配规律.结果表明:叶面积指数在一定密度范围内随密度增加呈增加趋势,R5期叶面积指数主要集中在冠层中上部;干物质阶段积累量、日积累量以及阶段积累量占总积累量的比例.均呈单峰曲线变化.干物质阶段积累量随密度的增加而增加,单株干物质日积累量随密度的增加而降低;单位面积株重、茎重、叶重、叶柄重及荚重均随着密度增加呈增加的趋势,R5期干物重主要集中在冠层中下部,并随着密度的…查看全部>>
Five planting density of Kennong 4 were set, plants were sampled at V4, RI, R3, RS, R6 stage and the change law of leaf area index(LAI) and dry matter( DM ) accumulation and distribution in five soybean populations were determined. LAI increased with the increase of planting density at a certain range. LAI at R5 stage concentrated in the upper and middle canopy. DM phase accumulation, daily accumulation and of total accumulation showed a single peak curve. D…查看全部>>
