近年来,随着新疆沙井子灌区膜下滴灌技术的推广应用,棉花种植面积逐年增加,部分棉田早衰现象有加重趋势,导致棉花植株矮小,蕾、铃脱落严重,铃质量减轻、纤维品质下降。针对沙井子灌区棉花膜下滴灌的种植模式,阐述了膜下滴灌条件下造成棉花早衰的主要原因,并介绍了应对棉花早衰的措施。
In recent years, with the popularization and application of drip irrigation technology in Shajingzi irrigation area in Xinjiang, the planting area of cotton increased year by year, and the phenomenon of premature aging of some cotton fields tended to aggravate. As a result, the cotton plants became short, the buds and bolls dropped seriously, the quality of the bell lessened, and the fiber quality declined. Aiming at the planting pattern of cotton under drip irrigation in Shajingzi irrigation area, the main causes of cotton premature aging caused by drip irrigation were expounded. Measures to deal with the premature decline of cotton were also introduced.
