通过对南疆棉田产量构成因素进行相关分析,研究南疆膜下滴灌棉田棉铃空间分布特征。结果表明:产量构成因素对皮棉产量的相关系数依次为亩铃数、铃重、亩株数、衣分,分别为0.6799、0.6499、0.3941、0.1836。亩铃数与皮棉产量呈极显著正相关。亩铃数、籽棉与亩株数的协同变化趋势明显。南疆棉田棉铃空间分布特征是以中、下部内围铃为主,挖掘上部铃的潜力。
Based on the correlation analysis of the yield components of cotton field in southern Xinjiang, the spatial distribution characteristics of boll cotton under cotton boll irrigation in southern Xinjiang were studied. The results showed that the correlation coefficients of yield components to lint yield were as follows: mu boll number, boll weight, mu number of plants and lint percentage, respectively 0.6799,0.6499,0.3941,0.1836. There was a significant and significant positive correlation between acreage and lint yield. The number of bells per acre, symbiotic change trend of seed cotton and acre number obviously. The spatial distribution characteristics of cotton boll in cotton field in southern Xinjiang is characterized by the middle and lower internal bells, and the potential of upper bells.
