【摘要】 采用回归分析方法对南疆主要棉区陆地棉含糖量与气候条件、土壤水分状况进行了相关分析,以确定影响棉花内糖变化的气候因素。结果明显遵循温度、降水量条件影响的变化规律,且依赖于空气相对湿度、5～50cm土壤水分状况的整体分布。更多还原

【Abstract】 Using the method of regression analysis,the correlation analysis are done on the sugar content and climatic condition and soil mosture in main cotton’s regions in southern area.The climatic factors on effecting the variation of cotton’s internal sugar are determined.It’s shown that the variation of cotton’s sugar content is interrelated with temperature and the rule of variation of precipitation and relative humidity and soil moisture of 5～50cm.更多还原
