棉花收获是棉花生产中的最后一关,适期采摘是获得高产、优质棉纤维的重要环节。据研究,棉花的最佳采摘期在棉铃开裂后的第4—7天,这个时期采摘的棉花铃重、衣分均最高,纤维品质最好。鄂荆92号此时采摘铃重为5.05克,衣分为40.5%,强度为4.04克,成熟度、色泽等俱佳。采摘过早(棉铃开裂后的第1—3天),由于积温不足,铃 Cotton harvest is the last step in the production of cotton, picking is the appropriate period of high yield, high quality cotton fiber an important part. According to the study, the best cotton picking period 4-7 days after boll cracking, cotton bolls were picked during this period, the highest points, the best fiber quality. At this moment, Jing-52 pick-bell weighs 5.05 grams, 40.5% is divided into clothes, and the strength is 4.04 grams. The maturity and color are all excellent. Picking too early (1-3 days after boll cracking), due to lack of accumulated temperature, bell
