摘要
为研究枣棉间作不同种植模式对棉花产量和水分利用效率的影响,以南疆枣棉间作棉花为研究对象,来探索最佳的间作模式和灌水量。结果表明:对棉花生长发育(株高、茎粗、果枝数、蕾数、开花数、铃数)而言,在常规水量300m3/667m2下间作模式1行、2行棉花的生长发育状况差别不大,但基本上都优于间作模式3行的棉花。对棉花产量而言,不同间作模式之间存在极显著差异,不同灌水量之间存在显著差异。间作模式3行、灌水量350m3/667m2的产量最高为3760kg/hm2与间作模式3行、灌水量400m,/667m2产量3612kg/hm2,间作模式2行、灌水量400m3/667m2产量3306kg/hm2之间无差异。故在南疆枣棉间作棉花产量较高的适宜间作模式为2~3行,灌水量为350~400m3/667m2。对棉花水分利用效率而言,不同间作模式之间存在显著差异,不同灌水量之间不存在差异。间作3行的棉花水分利用效率最高为5.6kg/(hm2·mm)与间作2行的棉花水分利用效率5.5kg/(hm2*mm)无差异,与间作1行的棉花水分利用效率4.3kg/(hm2·mm)有显著差异。故在南疆枣棉间作棉花水分利用效较高的适宜间作模式为2~3行。棉花产量和水分利用效率综合考虑(种植成本、枣树的生长发育),应该选择2行、灌水量350m3/667m2的种植模式。
In order to study of jujube cotton intercropping different planting patterns influence on cotton yield and water use efficiency, in southern xinjiang jujube cotton intercropping cotton as the research objection, to explore the best cotton interplanting mode and irrigation water. The results show that: On cotton growth and development, (plant height, stem diameter, branch number, number of buds, flower number, bell number), under the conventional water 300 m3/667m2 intercropping pattern lines 1, 2, cotton growth and development status of the difference is not big, but all basically is better than that of intercropping pattern 3 rows of cotton. For cotton production, there is an extremely significant difference between different interplanting mode, significant differences between different irrigation water. Intercropping mode 3 lines, irrigation water is 350 m3/667 m2 production up to 3 760 kg/hm2 and interplanting mode 3 lines, irrigation water is 400 m3/667 m2 production 3 612 kg/hm2, interplanting mode 2 rows, irrigation water is 400 m3/667 m2 production has no difference between 3 306 kg/hm2. Therefore, in the southern xinjing jujube cotton intercropping cotton yield higher intercropping patterns suitable for 2 - 3 lines, irrigation amount of 350 - 400 m3/667m2. For cotton, water use efficiency between different intercropping patterns significantly different and there is no difference between the different irrigation. Intercropping 3 rows of cotton has the highest water use efficiency (wue) of 5.6 kg/( hm2 * mm) and intercropping 2 lines of cotton water use efficiency ( wue ) of 5.5 kg/ ( hm2 * mm) no difference, and 1 row intereropping cotton water use efficiency (wue) of 4.3 kg/( hm2 * mm) had significant difference. Therefore, in the southern xinjiang cotton intercropping jujube higher water use efficiency of cotton intercropping pattern suitable for 2 - 3 rows. Cotton yield and water use efficiency into account ( planting costs, growth and development of jujube), they should choose two rows of irrigation 350 m3/667m2 of cropping patterns.
