Xinjiang temperature and light, rich in resources, and various types of climatic and ecological advantages with the production of various types of cotton fiber. The study of cotton quality is good, but a single type, it is difficult to meet the demand of market diversification problem, carry out the relationship between the cotton quality and temperature and light climate ecological factor in Xinjiang Ecological distribution patterns of cotton fiber quality, Xinjiang's cotton efficient and sustainable development of great significance. Cotton-growing acreage in the southern and northern quality traits typical cotton varieties were selected, phased seeding experiments in 2002 and 2004, respectively, in Shihezi Xinjiang 23 pilot multi-joint trials, analysis of the variation and fiber quality of cotton fiber quality under different temperature and light conditions in Xinjiang ecological distribution law, on the basis of suitable planting area of ??of in Xinjiang advantage cotton preliminary division, the main conclusions are as follows: a different fiber type varieties of quality variation and relationship with meteorological factors that climatic conditions in northern Xinjiang, commonly used indicators of cotton fiber, cotton fiber length, uniformity, and elongation mainly influenced by Genetic characteristics, the performance of early maturing varieties than late-maturing small varieties, environmental factors play a regulatory effect on the expression of genetic characteristics, rather than strength and micronaire by the combined effect of the Genetic characteristics and environmental factors. Different types of varieties than the intensity difference greater performance than late-maturing varieties of early maturing varieties than high strength. Stepwise regression analysis of the main fiber quality indicators boll stage meteorological factors, the total number of sunshine hours boll stage is the main climate factors affecting the fiber length and elongation; uniformity than the strength of the main subject boll stage active accumulated temperature ≥ 15 ℃; horse clone value by the maximum temperature of the boll stage. 2 in Xinjiang cotton fiber quality and meteorological factors relations and quality by Ecological distribution patterns the estimated the meteorological factor curve of different the pilot fiber quality indicators in Xinjiang and boll stage, the results show that: the fiber length and the elongation is mainly affected by the temperature and relative humidity, and showed a quadratic function of the relationship between temperature and relative humidity, at a temperature of 24 ° C to 26 ° C, relative humidity of 45% to 47% higher performance of fiber length and fiber elongation, when the temperature is 30 ℃, the fiber length shortest . Fiber strength and micronaire is mainly affected by temperature, sunshine hours and relative humidity. The positive correlation between the strength and temperature and sunshine hours was one element linear, quadratic function and relative humidity, relative humidity of about 54%, the lowest. Micronaire with a quadratic function of temperature and relative humidity, the temperature is 24 ℃ ~ 26 ℃ micronaire in A, B grade, was one yuan linear positive correlation with sunshine hours. Around the meteorological factor clustering analysis based on changes in the situation in Xinjiang 23 pilot different varieties fiber quality, and, combined with the ecological cotton-growing areas of climate resources, the initial division of the Xinjiang District advantages of cotton suitable for planting area. The eastern Xinjiang Turpan Basin in Xinjiang cotton production base, the area grown in upland cotton boll the developmental temperature boll stage average temperature about 32 ℃, sunshine 12h, relative humidity of about 35%, the precocious upland cotton showed length low elongation and uniformity, high strength, high micronaire inappropriate development in the long-staple upland cotton, can be used as high-strength the dedicated raw cotton production area. Three the southern Xinjiang the Yarkand River basin and Kashgar River Basin sparse attached, Markit, Bachu, the bell period average temperature 25 ℃ to 26 ℃, sunshine hours 10h ~ 14h, 40% to 48% relative humidity, is conducive to The high-quality fiber formation. Fiber strength, length, uniformity, elongation, micronaire belonging to the A, B two, fiber quality optimal. Can be used as high-count yarn spinning in long-staple upland cotton production area, with appropriate varieties for the production of high quality raw cotton cotton textile enterprises. Northern Xinjiang along the northern foot of Tianshan area, including the Manas River Basin, Kuitun River Basin, River Basin bortala, in the same oasis agriculture belt, the bell period average temperature of 24 ℃ ~ 25 ℃, sunshine hours 8h ~ 12h 48% to 58% relative humidity, planting a comprehensive indicator of the quality of early maturing varieties performed better fiber is longer, micronaire belonging to A, B grade, strength, uniformity, and elongation of several indicators in the middle, fiber better quality better varieties of the same type of quality consistency, suitable for high count yarn in the textile, suitable for building high-quality high-strength plush precocious upland cotton production base of industrialization. The edge of the southern Xinjiang Tarim Basin is located in the Weigan River Basin, the Tarim River Basin, the Kuqa River Basin, and the northern Xinjiang Ili River basin, eastern Xinjiang Hami Basin, from the analysis of quality indicators, although each individual quality advantage, The match between the indicators poor quality traits poor in these areas, the choice of varieties adapted to local conditions, give full play to the advantages of individual indicators can be provided for the production of multi-product specifications. Various types of varieties planted in the the southern Aksu River Basin area, and the Peacock River Valley were the shortest fiber length, fiber various quality indicators match poor, is not conducive to the growth of high-quality raw cotton, can be considered as a special low-count yarn spinning short staple cotton production area .
