Rice ridge is a new technology proposed in recent years to solve the problem of low yield fields such as winter paddy fields, muddy fields and sandy sand fields. In 1984, it was introduced from Sichuan Province and was tested in Chenggu, Yangxian and Xixiang counties. Flat for the mu yield of 76.7kg of rice; demonstration area in 1985 expanded to 2191 acres, an average of 46.68kg of rice by paddy, an increase of 10.74%. According to the region soil fertilizer station 1984-1985 multi-point determination of tillering period monolith than single, 3:00 mud temperature High 1.26 ℃, 6:00 low 0.265 ℃, hydrolyzed nitrogen increased 1.25ppm, available phosphorus increased 2.25ppm, total plant
