| 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。

| Abstract: | 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-resistant cottons both at home and abroad and conventional cotton.The studies showed that the yield of most domestic varieties of insect-resistant cotton was higher than the American cotton 33B,while there was no significant difference with those of the conventional cotton.T... |
