浙江省的蚕豆主要分布在各平原稻区以及滨海和江河下游的棉麻区。其中以杭嘉湖、宁绍平原种植面积最大,约占全省总栽培面积的四分之三。由于蚕豆是豆科作物,省工省肥,兼可培养地力,因此,在这些地区的复种轮作制中占有重要地位。 Vicia faba in Zhejiang Province are mainly distributed in the plain rice area and in the cotton-linen area along the coast and the lower reaches of the Yangtze River. Among them, Hangzhou-Jiaxing-Huzhou and Ningshao Plain had the largest planting area, accounting for about three-fourths of the total cultivated area in the province. Because broad beans are leguminous crops, saving labor and saving fertility, and can cultivate fertility, therefore, crop rotation in these areas occupy an important position.
