| 摘 要： | 南疆棉区高产栽培技术模式下陆地棉的干物质积累呈 S型曲线增长过程 ,高产棉花总积累的干物质为 1 1 8.7g/株 ,干物质增长最快的时段在 8月 2～ 1 2日(出苗后 85～ 95天 )。地上部干物质分配中心随生育进程发生着如下动态转移 :真叶→茎枝→蕾花→幼铃→铃壳→籽棉。棉铃内部的干物质分配、运输转移随时间及节位的变化呈现出有规律的变化

| Abstract: | The accumulative growth curve of the upland cotton can be described with the "S" type under the High-yielding cultivation techniques in South Xinjiang.The high yielding cotton accumulates 118.7 g dry matter per plant.From 2 August to 12 August(days of sprouting 85~95)the rate of dry matter accumulattion is the fastext.Durign the cotton growing season,the dry matter distribution has transferred as following true leaf→stem→bud and flower→young boll→boll shell→seed cotton.The results also indicated that the dry matter distribution and transfer in cotton boll change regularly with the plant time and the cotton node. |
