利用相关和通径分析方法研究了不同播期棉株同部位棉铃的有关性状对铃重和衣分率直接贡献的大小。分析了棉铃各性状与主要气候因素的关系,得出了铃期温度是影响棉铃发育的最重要气候因素,并进一步对铃期平均昼温、夜温、最高温度、最低温度及铃发育前期和后期的日均温对铃重、衣分率、籽指和衣指直接影响的大小程度进行了讨论。
Correlation and path analysis were used to study the direct contribution of bollworm-related traits to boll weight and percentage of different cotton bolls at different sowing dates. The relationship between the characteristics of cotton bolls and the main climatic factors was analyzed. The results showed that the boll temperature was the most important climatic factor affecting boll development, and further analyzed the effects of average day temperature, night temperature, maximum temperature, minimum temperature, Post daily average daily temperature on the boll weight, clothing fraction, the index finger and the direct impact of the size of the finger were discussed.
