Broad bean is one of the main spring grain crops in our county and is also a good winter green manure crop.In the coastal rice paddies and cotton areas, the perennial planting area accounts for about 20% of the spring grain area and the output accounts for more than 20% of the total spring grain output, In the area of Haimen District, the proportion is even higher, accounting for more than 40% .From years of practice, we can see that in the coastal rice area and cotton area, the planting area of broad beans is properly matched with that of wheat, rapeseed and green manure, Rice three cooked or soybean - cotton two cooked system, which is to improve annual output per unit area, improve soil structure,
