棉麦两熟棉纤维强度与铃期气象因子关系研究

研究棉麦两熟棉纤维强度与铃期气象因子关系的结果表明，相对湿度是影响棉麦两熟多类型、棉株多部位铃棉纤维强度的主要气象因子，相对湿度对纤维强度的作用均为负效应，作用大小因棉铃着生部位而异。日照时数对两熟春棉、温度对两熟短季棉棉株上部（７～９果枝）、顶部（１０以上果枝）铃棉纤维强度有重要作用，均为正效应。

Study of Relationship between Fiber Strength and Meteorlogical Factors at Bolling Stage under Cotton-wheat Double Cropping System

Investigation on the relationship between fiber strength in cotton-wheat double cropping field and meteorological factors at bolling stage were made and the results showed that relative humidity was the key meteorological factor to most cotton-wheat double cropping types and most position of bolls, effect of relative humidity affecting fiber strength was negative and degree of effect was different with the boll position changing. Hours of sunshine had an important function for double cropping spring cotton boll and temperature had an important positive function for upper(node 7 to 9) and top(node 10) bolls under double cropping system.
