在轮作倒茬中适当配置豆类、绿肥作物是扩大肥源、提高土壤肥力的有效措施,也是当前正规的草田轮作制尙未普遍实施的应急措施。参加到轮作中的豆类作物,从经济意义上看,蚕豆是比较有价值的。 Appropriate allocation of beans and green manure crops during crop rotation is an effective measure to expand fertilizer sources and improve soil fertility. It is also an emergency measure that is not universally implemented in the current grass field rotation system. To participate in the rotation of legumes, from an economic point of view, broad beans are more valuable.
