蚕豆高产栽培一般亩产250公斤左右,高的可超过500公斤。根据我县农民多年种植经验,要使蚕豆获得较高的产量,在栽培技术上应抓好以下几个环节:一、适时播种争壮枝据调查,亩产250公斤以上的蚕豆田,每株越冬前必须有3个以上的大分枝和4～5个小分枝。蚕豆从播种到出苗需有效积温120℃,从出苗到产生分枝的最适温度为16—20℃。若播种过迟,冬前发棵差,分枝不足,将会严重影响产量;相反,播种过早,由于气温高,分枝太多,群体过旺,不易控制,甚至冬前开花,遭受冻害。因此 Broad bean yield cultivation generally about 250 kilograms per mu, high can exceed 500 kilograms. According to our county peasants years of experience in planting, to make broad beans access to higher yields, cultivation techniques should do a good job in the following areas: First, the timely sowing Zhuang Zhuang According to the survey, more than 250 kilograms per mu yield of broad bean fields, each plant Before winter there must be more than 3 large branches and 4 to 5 small branches. Broad beans from sowing to emergence need effective accumulated temperature of 120 ℃, from the emergence of seed to produce the optimum temperature of 16-20 ℃. If sowing too late, winter before the bad weather, lack of branches, will seriously affect the yield; on the contrary, sowing too early, due to high temperatures, too many branches, the group is too busy, not easy to control, or even winter frost damage . therefore
