摘要
本文通过三年的密度试验得出:呼盟的春油菜单株结角层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。在华盖式结角层中,高效分枝所占的比例大,各枝序的结角起点高度和终点高度都较一致。华盖式结角层的生产力较高,是春油菜一种合理的结角层模式。
The trials of spring sown rape were carried out in 1987-1989 in Hailaer region of Inner Mongella for study relationship betwesn density and canopy tructure.The result was as follows; The pod canopy of single plant of spring rape showed an umbrella type in low density,like a Hua-Gai type in medium density and(?)a shuttle type in high densiy.There were many high efficient secondary branches pod canopy of Hua-Gai,the starting and terminating pod heights on every branch were uniform.The Hua-Gai type pod canopy had highly productivity,there by it was a kind of proper pod canopy model in spring rape.
