摘要
【目的】研究枣棉间作下不同灌水量对棉花生长发育的影响,以期找到适合南疆枣棉间作的最佳行距配置、最适灌水量。【方法】试验设置4个灌水处理和3个行间距配置,研究水分和间作模式对棉花产量及其构成因素的影响。【结果】灌水量和行间距配置均会影响棉花的生长发育、产量构成、空间分布。在灌水方面,棉花产量随着灌水量的增加而增加,到达一定程度后,随着灌水量的增加呈现下降趋势。在种植模式上,各行距配置间存在极显著差异,随着种植密度的增加,产量也相应增加,但在枣棉间作复合种植下,棉花过度密植会对红枣生长造成负面影响。【结论】综合考虑棉花和红枣的经济效益,灌水总量控制在300 m^3/667m^2,行间距即距红枣1.0 m时最佳。
[ Objective] The project aims to analyse the effects of different irrigation quantities on the growth and yield of the cotton in order to find the optimum row spacing and irrigation amount in jujube - cotton intercropping [ Method ] Experiments were carried out in Alar Tarim University Horticulture Station, in which 4 irrigation and 3 line spacing treatments were configured. [ Result] Irrigation water and row spacing could affect cotton growth, yield components, and spatial distribution. The cotton yield increased with increasing irrigation amount, but to a certain degree, with the increase Of irrigation amount, the yield would decrease. In the planting patterns on each row, there was significant difference between configuration, with the increase of planting density, the yield would increase. But the compound planting of jujube and cotton planting under ex- cessive growth would have a negative impact on the economic benefits of red dates. [ Conclusion ] Comprehen- sive consideration of cotton and red dates, irrigation amount should be controlled in W2 （300m3/667m2）, and the line spacing M2 （1.0 m from red dates） is the best.
