Huaiyin area over the past few years, vigorously expand green manure, to improve soil fertility and soil, great benefits. Maize intercropping summer green manure, crop lines can make full use of space, not competing with grain and cotton fields, welcomed by the masses. A team from Yangchang of Guanyun Commune in Guanyun County started to plant green manure (mung bean) on maize fields in 1959 and doubled the yield of wheat base wheat over the past four years.
