摘要
新疆机采棉喷施化学封顶剂与人工打顶方法进行对比,考察棉花农艺特性、产量品质和生产效果,为生产上使用化学封顶技术作为参考。结果表明,化学封顶的平均株高、果枝数、果节数以及结铃数都超过人工打顶的,在单铃重、衣分、籽棉产量、皮棉产量和纤维品质等方面化学封顶与人工打顶的差异较小。从而认为喷施“自封鼎”化学封顶剂能够有效抑制棉花的顶端优势,具有封顶效果。
To investigate the agronomic characteristics,yield quality and production effect of cotton by spraying chemical capping agent on machine-picked cotton and compared with manual topping method in Xinjiang,and to provide a reference for the use of chemical topping technology in production.The results showed that the average plant height,the number of fruit branches,the number of fruit nodes and the boll number of chemical topping treatment were higher than those of manual topping treatment,and the differences in single boll weight,lint percentage,seed cotton yield,lint yield and fiber quality between chemical topping treatment and manual topping treatment were small.Therefore,it is believed that spraying“Zifeng Ding”chemical capping agent can effectively inhibit the top advantage of cotton and has the capping effect.
