摘要
对新陆早 8号棉花品种不同产量 (1 80 0 ,2 0 2 5 ,2 2 50kg·hm-2 )水平下的冠层结构及其与干物质生产和分配、叶面积载荷量的关系进行了研究。结果表明 :皮棉产量在 2 0 2 5～2 2 50kg·hm-2 时 ,必须保持适宜的冠层结构 ,这样有利于干物质生产与分配。其中果节量为547× 1 0 4～ 564× 1 0 4个·hm-2 ,总铃数 1 0 7.8× 1 0 4～ 1 2 3 .8× 1 0 4个·hm-2 ,最大 LAI在 3 .2 0～3.70 ,成熟期 (9月初 )LAI保持在 2 .2 0～ 2 .80 ,每平方米叶面积载铃量在 2 9～
The relationship betweem high yield of cotton canopy structure, dry matter accmulation and distribution and sink capacity load of unit leaf area of variety Xin Lu Zhao 8 under three energy. Level rank from 1 800 to 2 250 kilogram per hectare were studied.The results showed that there must be the probable.Canopy structure to obtain lint cotton yield 2 025～ 2 250 kg·hm -2 .The fruit node of cotton is 54 700～56 400 node/hm 2,the total boll is 10 782～12 376 boll/hm 2,the maxi.LAI is 3.20～3.70,the LAI is 2.50～2.80 in the opening period, boll load of unit leaf area is from 29 to 33 boll/m 2.
