In recent years, the gradual development of peanut-rape-type oil two times a year, although more economic benefits, but because of red soil fertility is low. In particular, lack of organic matter, acid and thin plate knot serious phenomenon, poor physical properties of the soil, to improve the yield level of oil crops subject to great restrictions.
