Abstract:
According to the results of investigation in many years, the prectical effects of seven planting ways in yield, output value, precipitation economic bcnifit and precipitation application efficiency in the dry land of 01 Heilonggang area and in different hydrological years were analysed using methods of the grey theory and the multiple-objective grey decision.The planting ways suirble to various hydrological years at various input levels were described which may provide basis for scientific planting in Heilonggang area.
