棉花具有无限生长的习性,在适宜的条件下,生长时间越长,越易夺取高产。而我团属新疆西北内陆棉区之一,其气候特点是:无霜期短,其范围只有137—184天,平均157—160天,≥10℃有效积温3500—3900℃,春季气温回升慢,灾害性天气频繁,终霜期结束晚,不利于棉花早播,生长季节,光热资源多集中于6—8月,为冰雹多发区;秋季温度下降快,初霜来得早,不利于棉花的生长发育,特别是不利于棉纤维的生长发育;针对我团特殊的气候条件,在棉花生产中,我们为了争取在有限的时间内,夺取棉花生产的优质、高产、高效,我们以地膜密植栽培为基础,狠抓化学调控矮化这一关键性技术措施,取得了棉花生产的优质、丰产。
Cotton has the habit of unlimited growth, under the right conditions, the longer the growth period, the easier it is to seize high yield. My group is one of the inland cotton areas in the northwestern part of Xinjiang. Its climatic characteristics are: short frost-free period, only 137-184 days, with an average of 157-160 days, effective accumulated temperature≥10 ℃ 3500-3900 ℃, slow temperature rise in spring, Severe disastrous weather, the late end of the late frost period is not conducive to early sowing of cotton, the growing season, light and heat resources are concentrated in June-August, hail multiple areas; autumn temperatures fall faster, the early frost comes earlier, is not conducive to the growth of cotton Especially for the growth and development of cotton fiber. In view of the special climatic conditions of our group, in the cotton production, in order to win the high quality, high yield and high efficiency of cotton production within a limited time, Basis, pay close attention to chemical control dwarf this key technical measures, made in cotton production of high quality, high yield.
