影响我区棉花产量提高的主要因素,从当前看,一是土壤肥力低,化肥补量少,棉花苗期缺肥生长发育缓慢,盛花后缺肥早衰,中空脱落严重,故要走提高单株成铃而提高单产的道路是比较困难的。二是温度条件前期有余,后期不足秋后低温。尤其棉花始絮的9月中旬以后气温下降快,比南疆其他棉区低1.5—2度,严重影响棉铃、种籽和纤维的发育成熟,导致裂铃慢,吐絮不集

Affect the cotton production in our region to improve the main factors, from the current perspective, first, low soil fertility, less fertilizer, cotton seedling lack of growth and development of slow growth, lack of fertilizer after full bloom premature aging, severe hollow shedding, it is necessary to improve the plant It is more difficult to increase the yield of bells by the way of bells. Second, there are more than pre-temperature conditions, post-autumnal low temperature. In particular, the first cotton flocculation after mid-September temperatures dropped faster than other cotton areas in southern Xinjiang lower 1.5-2 degrees, seriously affecting the boll, seeds and fiber development and maturity, leading to slow crackle,
