春季冷空气活动频繁,夏季高温伏旱,秋季绵雨,是四川东北棉区的气候特点。多年来农技工作者,为了趋利避害、夺取棉花丰收,进行了多种形式的棉花整型试验,力求从中探索出一种与其气候特点相适应的整型方式。结果以每亩5000株,每株留5—7个果枝,每果枝留3—4个花蕾的矮株整型较好,经过精细管理,可以早熟高产。近年来,我们又在矮株的基础上进行改革:实行每亩5000株、每株留10个果枝,每果枝留2个花蕾的短果枝整型方式,
Cold air activity in spring is frequent, hot and summer drought in summer, autumn rain, is the climate characteristics of the northeast cotton area in Sichuan. Over the years agricultural workers, in order to profit and avoid disadvantages, to seize the cotton harvest, conducted a variety of forms of cotton plastic test, and strive to explore from the climate characteristics and adapt to an integer way. The results to 5000 per acre, leaving 5-7 per plant fruiting branches per fruit branch leaving 3-4 buds dwarf plant integer better, after careful management, can be early maturity and high yield. In recent years, we have carried out the reform on the basis of dwarf plants: implementing 5000 plants per acre, leaving 10 fruit plants per plant, leaving 2 flower buds per fruit branch,
