肥东县长临河公社种植粮肥兼用蚕豆,利用方法一是采食青莢,掩埋茎叶;一是割施嫩头,留养种豆,这样旣可抵一季午季收成(折合干重平均亩收八十五斤),又可抵一季綠肥(鮮茎叶每亩可收二千五百斤),在当前不与粮食爭地发展綠肥的前提下,具有扩大种植的价值。他們的經驗,主要是: 一、兼用蚕豆的种植面积必須安排适当,最好占稻田面积的三分之一。面积过大,采摘花工太多,农活错不开;面积太小,又不能滿足水稻基肥的需要。二、要注意因土种植。应安排在黄白土、油白土、黑粒土上,肥力太差的死黄土、澄白土以及地势低洼的田地均不宜种植。
Feidong County Linhe commune planted with grain and fat use beans, the use of methods is to eat green pods, buried stems and leaves; First, cut Shih Tau, keeping beans, so 旣 arrived in a quarter of autumn harvest (equivalent to dry weight average Mu), but also can reach the green manure in one season (up to 2,500 kilograms per mu of fresh stems and leaves). Under the premise of not developing green manures with food, it has the value of expanding cultivation. Their experience is mainly: First, the use of broad bean planted area must be properly arranged, preferably accounting for one-third of the paddy area. Too large area, picking too many flower workers, farm work is wrong; the area is too small, but also can not meet the needs of rice-based fertilizer. Second, pay attention to planting soil. Should be arranged in the yellow clay, oil white clay, black grained soil, poor fertility of dead loess, clear clay and low lying fields should not be planted.
