摘要： 为了探明翻耕深度对新疆膜下滴灌棉花生长的影响，通过设置3个翻耕深度（10 cm、30 cm和50 cm ）处理，研究不同翻耕深度对棉花农艺性状及产量构成的影响。结果表明，翻耕深度对棉花生育进程影响显著，翻耕30 cm和50 cm分别比翻耕10 cm全生育期延长20天和25天。同时翻耕深度增加使棉花株高、果枝数、主茎叶片数和单株铃数均显著增加，LAI增大。翻耕深度增加，棉花中、下部结铃比例减小，上部铃比例显著增加，同时皮棉产量显著增加，翻耕30 cm比10 cm增加52.9%，翻耕50 cm比30 cm增加9.2%。而收获株数和单株结铃数增加是皮棉产量提高的主要原因。综合分析认为，深翻耕有利于连作棉田棉花生长及产量水平提高。

Abstract: In order to ascertain the ploughing depth influence on cotton growth under membrane with drip rrigation in Xinjiang, the authors set the depth of ploughing of 10 cm, 30 cm, and 50 cm as three treatments, tudied of different depth of ploughing on agronomic characters and yield of cotton. The results showed that, epth of ploughing affected cotton development process significantly, the whole development process of loughing 30 cm and 50 cm were 20 and 25 days longer than that of ploughing 10cm. Depth of ploughing at the same time increased the cotton plant height, branch, main stem leaf and boll per plant significantly, and LAI increased as well. With increase of ploughing depth, the lower boll ratio of cotton decreased, and the upper fluid ratio increased significantly. Cotton lint yield increased significantly, lint yield of ploughing 30 cm was 52.9% more than 10 cm and lint yield of ploughing 50 cm was 9.2% higher than 30 cm. The number of boll per plant was the main cause of lint yield increase. Based on the results, deep ploughing was helpful for cotton growth and yield increase on continuous cropping in cotton field.
