棉花进入蕾期的生长特点是:营养生长与生殖生长并进,但以营养生长为主,并一直延续到开花盛期。需肥由苗期以氮代谢为主,转变为以碳代谢为主。蕾期的管理目标是兼顾营养生长和生殖生长,搭好丰产架子,积累较多的有机营养,为花期减少脱落多结铃做好准备。1、健壮棉田管理。植株茎秆粗壮,主茎节间短,新叶盖顶凹陷,蕾壮柄粗苞叶紧,主茎叶片由小到大,叶片大小适中,叶厚度较薄。健壮棉田,促控结合。蕾期控制,初花期适当促进。盛蕾期亩喷缩节胺0.5克左
The growth characteristics of cotton into bud stage are: vegetative and reproductive growth go hand in hand, but mainly to vegetative growth, and has continued into the flowering period. Fertilizer need nitrogen from the seedling stage mainly to carbon-based metabolism. Budgeting management goal is to take into account the vegetative and reproductive growth, set up high-yield shelves, accumulate more organic nutrition, for the flowering to reduce shedding more than the bell to prepare. 1, robust cotton field management. Stalks plant stout, the main stem internodes short, the new leaves covered the top of the depression, buds bracts thick bud tight, the main stem leaves from small to large, moderate leaf size, thin leaf thickness. Robust cotton fields, promote control combination. Bud control, early flowering appropriate promotion. Sheng Lei mu spray sprinkler amine 0.5 grams left
