蚕豆是我省一种大宗的夏粮作物和饲料作物。常年种植面积近360万亩,居全国首位,是全国蚕豆主产区之一。我国的蚕豆种植面积又居世界首位,产量占世界产量的80%。蚕豆生产的好坏,对粮食、畜牧业、食品加工业的发展具有重要作用。蚕豆属豆科作物,根瘤菌可以固氮养地。据研究:一亩蚕豆可固氮13～17.5公斤,有残枝、落叶及根茬500～700公斤,对提高土壤含氮量和有机质有明显效果。增施农肥,培肥地力,是蚕豆高产的基础。在施农肥的基础上,配合施用磷、钾肥增产十分显著。蚕豆需要一定的氮、磷、钾,特别需要磷、钾肥。施肥原则以
Broad bean is a province of the bulk of summer crops and feed crops. Perennial planting area of nearly 360 mu, ranking first in the country, is one of the main producing areas of broad bean. China’s broad bean planted area and occupy the first place in the world, the output accounts for 80% of the world’s output. The quality of broad bean production plays an important role in the development of grain, animal husbandry and food processing industry. Fava beans leguminous crops, Rhizobium nitrogen fixation. According to the research: One mu of fava beans can fix 13 ~ 17.5 kilograms of nitrogen and 500-700 kilograms of stumps, fallen leaves and stubble, which have obvious effect on increasing soil nitrogen content and organic matter. Increase of manure, fertility fertility, is the basis of high yield of broad beans. On the basis of the application of fertilizer, with the application of phosphorus, potassium fertilizer yield is very significant. Broad beans need some nitrogen, phosphorus, potassium, in particular, need phosphorus, potassium. Fertilization principle to
