摘要
应用 FAO生态区域法等测算结果 ,北疆棉花光合皮棉生产力理论上限为每公顷 2 0 0 0 7.6kg,北疆各地平均光温皮棉生产力为 2 72 1～5 4 1 9.5 kg,最大光温皮棉生产力达 60 4 5 .0 kg。棉花增产潜力在 1 998年的基础上尚可增加 1 .63～4.2 6倍。北疆棉花光合生物量最大光能利用率为7.5 8% ,生物量光温光能利用率为 2 .0 34%～2 .1 1 0 % ,子棉光温光能利用率为 0 . 81 3%～1 .0 5 5 % ,皮棉光能利用率为 0 .2 76%～ 0 .474%。从而为北疆的棉花持续增产。
By application of method of ecology area, productivity of cotton and the sun light utilization rate of cotton in north of Xinjiang were worked out. The results showed the limited photosynthetic productivity of lint was 20007.6 kg·hm 2 in theory, the most light temperature productivity of lint was 6045.0 kg·hm 2 .According to measure of production potential of cotton, the yield of cotton will increase by 1.63 to 2.26 times than 1998's in north of Xinjiang. The paper provides information for cotton persistence yield increase, cultivation techniques of cotton high yield and theory study.
