摘　　要：以鲁棉532为供试品种,研究4个种植密度(6.75万株/公顷、8.25万株/公顷、9.75万株/公顷、11.25万株/公顷)对麦后直播短季棉农艺性状、产量和效益的影响。结果表明:随着种植密度的增加,棉花株高逐渐增高,果枝数、单株结铃数减少,铃重减轻,经济效益增加且处理间差异显著;纤维品质指标处理间差异不显著,且整齐度指数和伸长率差异不大;种植密度为8.25万株/公顷和9.75万株/公顷时籽棉产量、皮棉产量和单位面积经济收益较高。综合认为,鲁西南地区麦后直播短季棉的种植密度在8.25万株/公顷与9.75万株/公顷之间为宜。The effects of four planting densities(67500, 82500, 97500 and 112500 plants/hm~2) on agronomic characters, yield and benefit of direct seeding short season cotton after wheat were studied with Lumian 532 as the tested cotton variety. The results showed that with the increase of planting density, the plant height of cotton gradually increased, the number of fruit branches and bolls per plant decreased, and the boll weight was lighter, the economic benefit increased, and the difference between treatments was significant;The difference in fiber quality index was not significant, and there was little difference in uniformity index and elongation;When the planting density is 82500 to 97500 plants/hm~2, the yield of seed cotton and lint of cotton and the economic income per unit area are higher. It is generally believed that the planting density of early maturing cotton varieties of direct seeding short season cotton after wheat in Southwest Shandong cotton planting area should be between 82500 plants/hm~2 and 97500 plants/hm~2.
