硼对棉花的生长发育有很大影响。棉花缺硼表现叶片卷曲皱缩,顶端生长点受阻,簇生顶端生长点增多。花、蕾铃发育不正常,茎和叶柄维管束受损,间断褐色的坏死组织或暗绿色、褐色环带,重者出现蕾而不花现象。棉花施硼后,可明显提高产量,改善品质,提高抗病能力。平均增产8.1％,亩增产皮棉6.5公斤,多增加收入22.90元(按每公斤单价3.52元计)。施硼比不施硼的棉株高度增加1.27厘米,单株果枝数和伏前桃增加0.2个,单株铃数增加0.07个,铃重增加0.22克,落铃率降低1％,纤维长度增加0.19毫米,衣分率提高0.5％。
Boron has a great influence on the growth and development of cotton. The lack of boron showed curly folds of cotton leaves, the top growth point was blocked, and the top of tufted growth point increased. Flowers, buds are not normal development, damaged stem and petiole vascular bundles, intermittent brown necrotic tissue or dark green, brown belt, severe buds appear instead of flowers. After the application of cotton boron, can significantly improve yield, improve quality, improve disease resistance. An average increase of 8.1%, 6.5 kg of mu lint yield increase of more income 22.90 yuan (3.52 yuan per kilogram price). Compared with the non-boron-applied cotton plants, the boron application height increased by 1.27 cm. The number of fruit branches per plant and the number of peaches increased 0.2, the number of bolls per plant increased by 0.07, the boll weight increased by 0.22g, the rate of fall boll decreased by 1% and the fiber length increased 0.19 mm, clothing fraction increased by 0.5%.
