A Cultivation Technique of Direct Seeding Rice Adapted to Cold Soaked Mud Field in the Mountains Southwest Hubei

The S-W Hubei area is located in the southwest of Hubei, with high-elevation terrain, unique climate, and lots of cold soaked fields. On account of the environmental characteristics of cold soaked mud fields, the procedure of direct seeding cultivation within ridging and plastic film mulching was introduced. The application of this technique can exalt the tiller node, increase the available soil nutrients of cold soaked mud fields, and improve the economic structure and the technical effect of yield, and the corresponding recommendations on the application of mechanical support, economic cost and technical standard were made.
