| 摘 要： | 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...

| Abstract: | Five planting density of Kennong 4 were set,plants were sampled at V4,R1,R3,R5,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.DM phase accumulation increased with increase of planting densi... |
