Early maturing cultivation is an important measure to promote the multi-cropping and high-yielding dry-land crops and increase the output value through the effective use of the production capacity of environmental resources such as light, heat and water in different crop-type communities in suitable geographical areas. Dejiang is located in the northeast of Guizhou, Yunnan-Guizhou Plateau to the Western Sichuan hilly slope transition zone. The total area of 2077 square kilometers of the county, a total area of 576547 acres of arable land, of which dry land accounts for 51% of arable land, with the conditions for the development of dry land more cooked.
