要从栽培上改进棉花品质,必须首先了解环境条件与纤维品质的关系,进而探讨优质棉高产的栽培途径及关键性技术措施。一、环境条件与纤维品质的关系 (一)温度的关系。棉铃和纤维的发育与温度的关系尤为密切。纤维生长的适宜温度范围为20～30℃,在此范围内,温度愈高,纤维素的淀积愈快,当夜温低于21℃时,纤维素的淀积就会受影响。棉铃发育的临界温度在15℃以上,
To improve cotton quality from cultivation, we must first understand the relationship between environmental conditions and fiber quality, and then explore the high-quality cotton cultivation methods and key technical measures. First, the relationship between environmental conditions and fiber quality (a) the temperature relationship. The relationship between cotton boll and fiber development is particularly close to temperature. The optimum temperature range for fiber growth is from 20 to 30 ° C. Within this range, the higher the temperature, the faster the deposition of cellulose. When the night temperature is below 21 ° C, the deposition of cellulose is affected. The development of cotton boll temperature above 15 ℃,
