沙井子位于塔里木的西北边缘,北纬40.43°,东经79.51°。气候干燥、降水量少,年雨量61.8—102.1毫米,多分布在6—8月,以8月为多;蒸发量为年雨量的40倍。一般气温高,无霜期长,日照充足。在大多数的年份里,春季气温不稳定,夏季炎热,4—10月平均气温20.5℃,7月平均气温26.9℃,秋秀的9月气温下降迅速,其平均气温仅22.8℃,而10月只有10.8℃。枯霜期多出现在十月中旬,平均无霜期197天。 由于这些气候的特点,使长绒棉在连年栽培中,表现了成熟晚,产量低,霜前花少,后期容易促长和纤维品质不能满足要求。为了大力发展长绒棉,满足国家需要,我们在生产实
Shajingzi is located in the northwest edge of Tarim, latitude 40.43 °, longitude 79.51 °. The climate is dry with a little rainfall. The annual rainfall is 61.8-102.1 mm, mostly distributed in June-August, mostly in August; the evaporation is 40 times of the annual rainfall. General high temperature, frost-free period, adequate sunshine. In most years, the spring temperature is not stable, the summer is hot, the average temperature in April-October 20.5 ℃, July the average temperature of 26.9 ℃, autumn show the temperature dropped rapidly in September, the average temperature of only 22.8 ℃, and only in October 10.8 ° C. Burning frost period appear in mid-October, the average frost-free period of 197 days. Due to the characteristics of these climates, the long-staple cotton shows late ripening, low yield, less frost before frost, easy to grow later and fiber quality can not meet the requirements. In order to develop long-staple cotton, to meet the needs of the country, we are producing real
