【摘要】 对高产条件下泗棉3号棉铃增重的理想株型指标进行了研究。结果表明:主茎和果枝节间保持适宜的长度、较多的果枝数及适宜的节枝比,可增加果枝粗度,尤其是上部和中部外围的果枝粗度,增加中上部果枝向值,是高产棉铃增重的结构基础;果枝向值这一指标可衡量果枝和叶片的着生状况。更多还原

【Abstract】 By studying the optimum plant type index of cotton boll weight increased of Simian 3 in high yield, the results showed that the optimum internode length of main stem and fruit branch, the optimum ratio of fruit node/fruit branches, high fruit branches, increased fruit branch diameter, especially the diameter of the middle and upper part of the plant, from the lower to upper part, decreased angel between the main stem and fruit branches was the basis for the increase of boll weight. The character of fruit branches and leaf can be express by the index of fruit branch toward main stem.更多还原
