摘　　要：通过比较国产抗虫棉与国外抗虫棉、常规棉在叶面积发育、物质积累、生殖量以及产量构成因素等方面的差异,分析国产抗虫棉的产量形成特征。结果表明,目前推广的大多数国产抗虫棉品种产量都高于美棉33B,与常规棉产量差异不明显;产量构成因素中,国抗棉的单株成铃数和衣分均优于常规棉和美棉33B,但单铃重却小于常规棉;国产抗虫棉品种前期总生殖量明显高于国外抗虫棉和常规棉,肥水需求较早。The characteristic of yield formation of the domestic insect-resistant cotton was analyzed through comparing the differences of leaf area development, dry matter accumulation, reproductive capacity as well as yield components among insect-re- sistant cottons both at home and abroad and conventional cotton. The studies showed that the yield of most domestic varieties of in- sect-resistant cotton was higher than the American cotton 33B, while there was no significant difference with those of the conven- tional cotton. The boll number per plant and lint percentage of domestic insect-resistant cotton was higher than conventional cotton and U.S. cotton 33B, but the single boll weight was less than conventional cotton. The biomass production of the domestic in- sect-resistant cotton was significantly higher than those of foreign cotton and conventional cotton in early stage, and the demands of fertilizer and water was also earlier.
