The conprehensive arrangoment technical system that takes the rotation of grain - bean -grass as a center has been developed in semiarid areas with soil and water loss of South Ningxia。The system is able to make the rotation into systematization
the culture into standardization andmanure application into patternization
the efficiency of energy transformation
crop yield and to-tal yield in this system can be increased by 14. 7 percent
1. 2 time and 1 time respectively。Among those the balanced manure spreading in rotation can not only coordinate the balance of major nu-trients and periodicity between need and supply
but also improve the ability and stability of ad-justment and control for soil nutrients in this system.
