摘要: 灌浆强度(x_1)和灌浆时间(x_2)与粒重(Y)的关系呈多元非线性回归方程 Y=ax_1~(b1)·x_2~(b2),但 x_1的相对作用大于 x_2,乃致在快增期 x_2的作用可以忽略不计。抽穗后缺肥加剧 x_1对籽粒增重的限制,而施肥削弱 x_1对粒重的相对影响并消除 x_1与 x_2之间的负互作。x_1对粒重的相对影响总是弱势粒大于强势粒,但弱势位 x_1和 x_2

Abstract: The relationship between the filling intensity (x_1)and the filling du-ration(x_2)corresponding to the grain-weight(Y)was expressed by the cur-vilinear regression equation Y=aX_1~(b_1)X_2~(b_2).In the whole process of incre-asing grain-weight,the relative effect of X_1 was higher than that of X_2and
