摘 要:依据《新疆棉花区划新论》,从光热资源的角度,对新疆各个棉花分区的光合生产潜力、光温生产潜力进行了测算与分析。结果表明,新疆光热资源丰富,各棉花亚区的光合生产潜力都很高,平均高达13076.7kg·hm^-2,是近三年棉花平均现实生产力的8.6倍。光温生产潜力达4391.2~5502.6kg·hm^-2,比现实生产力高出2.3~3.9倍。其中,中熟棉亚区的光温生产潜力最高,达5502.6kg·hm^-2,其余依次是早中熟棉亚区、早熟棉亚区、特早熟棉亚区。According to New Theory of Compartmentalizing Xinjiang Cotton Regions, the radiation production potential and thermal production potential in every cotton sub-region of Xinjiang were cal-culated and analyzed based on light and heat resources. The results were as follows: Xinjiang were a-bundant in light and heat resources, the radiation production potential of cotton was very high in each cotton sub-region. The mean value was 13076.7 kg·hm^-2 ,which was 8.6 times of its average yield the last three years. The thermal production potential o f Xinjiang cotton accounted 4391.2 kg · hm^-2 to 5502.6 kg · hm^-2, but it was still 2.3 to 3.9 times higher than its reality production. Among various cotton sub-regions of Xinjiang, the thermal production potential in mid maturity cotton sub-region was highest, the value hit 5502.6 kg · hm^-2. From high to low, the rest were early mid maturity cotton sub-region, early maturity cotton sub region and special early maturity cotton sub-region.
