2008—2009年分别用中棉所50和中棉所68进行田间试验,研究大麦后地膜精播棉的产量构成和形成特点。结果表明,早熟棉品种中棉所68和中棉所50于大麦后地膜精播,能够表现早熟早发、结铃集中的特性,使成铃高峰与有利结铃的气候条件较好地相遇,成铃率明显提高,铃重增加,能够获得高产;本试验中皮棉产量接近1 500 kg/hm2,并以优质铃为主。
2008-2009 years with the Cumin 50 and China cotton 68 in the field trials to study after barley sowing cotton yield composition and formation characteristics. The results showed that the precocious cotton varieties Zhongmamian 68 and Zhongmian 50 were fine sowed in the mulching of barley, which could show the characteristics of early ripening and boll gathering, so that the climatic peaks of the boll height and the favorable bolls met well, The boll rate increased significantly, the boll weight increased, and the high yield could be obtained. In this experiment, the lint yield was close to 1 500 kg / hm2, with high quality bell-dominated.
