蚕豆是我队重要的粮食作物,每年种植面积占粮食播种面积的30％左右。我们经过多年试验,初步摸索出宽窄行种植方法,使亩产量由原来等行距种植的三、四百斤提高到七、八百斤。一九七五年我队大面积采用宽窄行培土种植法,一百二十亩蚕豆平均亩平达到八百九十斤。原来的等行距种植,一般是用犁开沟,人工点种或溜种,行距八寸,株距三寸,每亩下 Broad bean is our team an important food crops, planting area accounts for about 30% of the sown area of ​​grain each year. After many years of experiments, we initially explored the planting methods of wide and narrow rows, raising the output of mu from three or four jin from the original row spacing to seven or eight jin. In 1975, a large area of ​​our team adopted wide-width line and peat cultivation methods. The average mu level of 120 mu of broad beans reached 890 kilograms. The original line spacing planting, the general is to use plow ditching, artificial point species or sowing, spacing of eight inches, spacing three inches, per acre
