【摘要】 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。更多还原

【Abstract】 During the period of flowering and bearnig fruit, the spraying of micronutrient boron can raise the photosynthetic intensity of cotton’s leaves and accelerate carbohydrate’s formation, accumulation, transportion and distribution. It can also stimulate the development of cotton’s bolls, fibre and seeds. So the weight of bolls are increased and the ginning outturn, lint index and seed index are enhanced. In addition to these, the spraying of boron will make fibre longer, stronger and finer. All of these show that the spraying of boron can improve the technological quality of cotton fibre and reap a produce more with good quality of the culture of cotton.更多还原
