棉株疯长是影响棉花高产的重要原因.棉花生长稳健,发育正常,结桃就多,产量就高。但在棉花生长发育过程中,极易造成疯长.出现叶枝多,营养生长过旺,花蕾、铃脱落率高,结桃少,形成植株“高大空”,产量就低。一般出现下列情况即为棉株疯长.一是主茎日增长量过快.正常生长的棉株,其主茎的日增长量,苗期为0.5厘米～0.8厘米,蕾期为1厘米～1.5厘米,盛蕾初花期为2厘米～2.5厘米,花铃期为1厘米～1.5
Soaring cotton plants is an important reason for the high yield of cotton.Cotton grows well and develops normally, with more fruits and more yield. However, during the process of cotton growth and development, it is extremely easy to cause insane growth, with many branches and vegetative growth, excessive flower buds and bolls, high rate of flower buds and fewer peaches, and the formation of plants “tall and empty” with low yield. The general emergence of the following conditions is soaring cotton plants. First, the main stem growing too fast. Normal growth of cotton, its main stem daily growth, 0.5 cm to 0.8 cm seedling stage buds of 1 cm to 1.5 Centipede, flowering early flowering is 2 cm ~ 2.5 cm, flower bell period of 1 cm ~ 1.5
