蚕豆并非低产作物,其增产潜力很大,从全国的高产典型来看,单产已闯过600—800斤。我们试验的高产田在1979—1981的三年中,亩产籽粒均在500—600斤。试验证明,要想获得高产,必须保证“年前枝,年后身,上开花,下结荚”的长势,长相。因此,以争早苗、全苗;争粗壮分枝;争荚多为目标,狠抓以下几个有效措施; Broad bean is not a low-yield crop, its yield potential is very large, from the country’s high-yield typical point of view, yield has passed 600-800 pounds. In the three years from 1979-1981, the high-yielding fields we experimented with were 500-600 jin per mu. Test proved that, in order to obtain high yield, we must ensure that “years ago, year after body, flowering, pod under” the growth, appearance. Therefore, in order to fight San Miao, all seedlings; fight stout branches; fight more than as the goal, pay close attention to the following several effective measures;
