1979—1980年,我们对高、中、低、间套、旺长等类型的棉田进行了观察研究,并对每类型10株样本进行了调查统计,发现棉花主茎、果枝粗度比与结铃率的关系非常密切,并表现一定的规律性,值得重视和研究.一、茎枝比与结铃率的相应关系茎枝比,就是棉花主茎直径与其同节位果枝直径之比.它们的比值与结铃率呈高度负相关(r=-0.9908),其迥归方程为
From 1979 to 1980, we observed and studied the cotton fields of high, medium, low, medium and long varieties, and conducted a survey and statistics on 10 samples of each type. The results showed that the ratio of coarseness and fruiting branches of cotton to knot The relationship between the boll rate is very close, and the performance of a certain regularity, it is worthwhile to pay attention to and study.First, the ratio of stem to branch ratio and boll ratio The stem to shoot ratio, is the ratio of cotton main stem diameter with the same node diameter of fruit branch. (R = -0.9908), the regression equation is
