Review and Prospect of Dryland Eco-Agriculture Research of Dingxi Experimental Station, GAAS, China

Emphasized at the Gaoquan model of small watershed vulnerable environment divisional managing system,the new crop anti-drought farming system of whole growing period plastic film covering spring wheat planting technique,the compensation and over-compensation effect of supplying irrigation after critical drought,the high efficient water harvesting agriculture system,and the sustainable high-efficient eco-agricultural and rural economy developing way consist of developing industrial production of potato,Chinese herb-medicine and mushroom,that being result from the past two decades persisting study.The paper systematically reviewed the prominent contribution of Dingxi Experimental Station of Gansu Academy of Agricultural Sciences on the research and science development of dryland eco-agriculture in Gansu,China.Based on it, the key research and development fields during the coming national eleventh-plan period have been put forward for discussion.
