改善蚕豆的产量,栽培上普遍围绕不同的群体结构(以密度为主),研究产量成份的变化对产量的影响。Keller等的研究指出,蚕豆的产量随单位面积上总干物产量的增加而上升。但是Thompson表示,收获指数低,仅干物产量高也不增产。认为花荚期的光照状况是影响蚕豆产量的一个因素。打顶,调整株行距,虽改善光照条件,据Due Improve the yield of broad bean, cultivation generally around different groups structure (density-based), study the impact of changes in yield components on the yield. Studies by Keller et al. Show that the yield of broad beans rises with the increase of total dry matter per unit area. However, Thompson said the harvest index is low, and only high dry matter production does not increase production. It is considered that the light condition during flowering and podding stage is a factor that affects the yield of broad bean. Topping, adjust the row spacing, although to improve the lighting conditions, according to Due
