我县蚕豆面积约占小春播种面积的40％,总产占小春粮食作物的43％左右。1978年以来蚕豆连续四年获得丰收。1980年6.5万亩蚕豆平均单产达到426斤,比1978年单产386斤每亩增产40斤,总产增加400万斤,海东公社4189亩蚕豆平均亩产达到542斤。1981年全县种植6.88万亩蚕豆,种植质量好,群体结构比过去合理,苗架长势喜人,但因蚕豆开花结荚期受三月份低温的影响,致使百粒重普遍降低10—14克,比1980年略有减产,据初步统计,单产可达408斤。湾桥、银桥、七里桥三个公社是我县蚕豆产量最低的公社,1970年以前蚕豆亩产只有150斤左右。银桥公社1977年8210亩蚕豆
The area of broad beans in our county accounts for about 40% of the sown area of Xiaochun, with the total output accounting for about 43% of Xiaochun food crops.
