Broad bean is one of the main summer grains of our county and also an important green manure crop.Especially my county is located in the coastal area of northern Jiangsu Province with a small amount of organic matter and contains varying degrees of salinization and development of broad bean as winter green manure, Therefore, in recent years, the planting area has been expanded year by year, but the disease has a great threat to the high yield and stability of broad beans.In order to solve this problem, we conducted investigation and scientific experiments since 1973, Have made some results, are summarized as follows:
