通过3年的密度试验得出:呼盟的春油菜单株结角层是模式在低密度下呈伞形;适宜密度下呈华盖式;高密度下呈梭形。在华盖式结角展中,高效分枝所占的比例大,各枝序的结角起点高度和终点都 Through 3 years of density test, it was concluded that the spring cotyledon was the umbrella with the pattern of low density, the canopies at the appropriate density, and the fusiform at high density. In the Chinese-style junction show, the proportion of efficient branches, each branch of the starting point of the knot height and the end are
