| 摘 要： | 为了明确南疆膜下滴灌模式下常规棉适宜的种植密度，选用中棉所49和中棉所41为试材，设种植密度9．0万株／hm2、13．5万株／hm2、18．07万株／hm2、22．5万彬hm2、27．0万彬hm2和31．5万株／hm2计6个处理．于2008～2010年在阿拉尔市进行了不同密度对棉花籽棉产量影响的试验。结果表明：种植密度为22．5万株／hm2和18．0万株／hm。时能获得较高的籽棉产量，本研究条件下理想的种植密度为24．08万株／hm2。

| Abstract: | Investigation was undertaken in the experiment field in Alar City from 2008 to 2010,in order to study suitable planting density of conventional cotton with drip irrigation under mulch in Southern Xinjiang.The effects of different planting densities on seed cotton yield was mainly studied.2 CCRI 41 and 49 were used in the field experiment,planted with 6 different densities.The results revealed that the treatment of 225 000 plant/hm2and 180 000 plant/hm2 had much higher yield.The ideal planting density was 24... |
