【摘要】 研究麦棉两熟棉铃铃重与铃期气象因子关系的结果表明,日照时数是影响麦棉两熟多类型、棉株多部位铃重的主要气象因子 ,温度对棉株上(7～9果枝 )、顶 (10以上果枝 )部铃铃重有重要作用 (尤其对两熟短季棉 )。铃重与铃期主要气象因子的相关存在二次曲线 (Y=A +BX2)和双曲线[Y=X/(B +AX)]两种类型。日照时数对铃重的作用因麦棉两熟和棉铃着生部位而异 ,作用重要部位在中部 (4～6果枝 )更多还原

【Abstract】 Investigation on the relationship between boll weight in wheat-cotton double cropping and meteorological factors in boll period showed that hours of sunshine was the key meteorological factor to most wheat-cotton double cropping patterns and most position of boll,and also temperture had an important function to upper(node 7to 9)and top (≥node 10)boll especially for double cropping short season cotton.Boll weight had close relationship with main meteorological fators during the boll development,in which it could be expressed by quartic curve equation (Y=A+BX2)or double curve equation [Y=X/(A+BX)].Effect of hours of sunshine affecting boll weight was different as the wheat-cotton double cropping patterns and boll position change,the main boll position was in the middle (node 4 to 6).更多还原
