在花铃期,喷施微量元素硼能提高棉叶光合作用强度,加速碳水化合物的形成、积累和转运分配。促进棉铃、纤维和种子的发育,增加铃重,提高衣分、衣指及籽指。此外,喷硼后增加了纤维长度,提高了纤维的强力和细度,有利于棉纤维工艺品质的改进,也有利于棉花栽培获得优质高产。 During the flower-boll stage, the application of trace element boron can improve the photosynthesis of cotton leaves and accelerate the formation, accumulation and transport of carbohydrates. Promote the development of bolls, fibers and seeds, increase the boll weight, improve the lint, fingers and fingers. In addition, after boron spraying, the fiber length is increased, the strength and fineness of the fiber are increased, the improvement of cotton fiber craft quality is also facilitated, and the high quality and high yield of cotton cultivation is also favored.
