| 摘 要： | 对新疆麦套棉生长发育特性的研究表明:新疆麦棉套作小麦与棉花共生期达50 d,全生育期套作棉比单作棉长4 d,共生期套作棉株高、茎粗、叶龄等小于单作棉,但共生期后,套作棉的生长速率要快于单作棉,最终反超单作棉。套作棉开花前叶面积指数小于单作棉,开花后则高于单作棉,直至吐絮。套作棉单株结铃性强、铃大,皮棉产量1 338.4 kg/hm2,占同面积单作棉的64.6%。

| Abstract: | The study on the growth and development of the wheat-cotton intercropping of Xinjiang indicated that the open boll stage in the wheat-cotton intercropping is later than that of monoculture cotton,and growing period is 4 days longer than monoculture cotton because the symbiosis period has 50 days,and the agronomic character such as plant height,stem diameter and leaf age are less than monoculture;but the growth rate of intercropping cotton than that of monoculture cotton after symbiosis period.At last,intercropping cotton surpassed monoculture one in all aspects.The peak of leaf area index is 2.77 in wheat-cotton intercropping on the July 25th.The output of ginned cotton in intercropping cotton is 1 338.4 kg/hm2 about 64.6% in monoculture cotton. |
