Demonstration technical standard of grain-soybean rotation mode with dwarf and dense planting crops as the main body ( technical specification )

Aiming at the key problems of farmland soil erosion, farmland non-point source pollution and farmland soil acidification in the protection of black soil cultivated land in water source area, the causes of black soil degradation in water source area were analyzed in depth, and a number of key core technologies such as varieties and biological pesticides were integrated. Based on the principle of coordinated production ecology, equal emphasis on increasing production and efficiency, and supporting good varieties and methods, a grain-soybean rotation model with dwarf and dense crops such as soybean, wheat, forage rape and dwarf sorghum as the main body was constructed.

The basic data were obtained in the production practice, and the technology integration was carried out according to the conventional cultivation techniques of soybean, wheat and sorghum.
