March 2003 to August 2004 , three different types of areas for the Ningxia Hui Autonomous Region , the Yellow River Irrigation water use efficiency in the agricultural production of the arid zone in central and southern mountain low, serious soil erosion, high input costs , exploration suitable for integrated within the different regions of Ningxia better conservation tillage technology mode , provide a theoretical basis for the demonstration and extension of conservation tillage in Ningxia . The test from the stimulation effect , water-saving effect and the efficiency of the section between the different conservation tillage technology mode and conventional tillage compared results are as follows : 1 , compared with the traditional ways of farming , in addition to Yuanzhou District other than cuts, reduction in tillage sowing directly in conservation tillage technology , other points of conservation tillage techniques are demonstrated to reduce the mechanical operating cost ( reduced by 3 to 61 $ / 667m2 ) Paul accumulator soil moisture , increase water use efficiency ( increased by 36.2% to 56 %) increase crop yields ( an increase of 4.11% to 43 3 % ) and the section of the income ( an increase of 53.16 yuan / 667m2 ~ 92. 40 / 667m2) effect. 2 , water conservation , increase the income effect comprehensive analysis , Ningxia different ecological zones suitable conservation tillage technology model : (1 ) in irrigated areas of the appropriate spring wheat conservation tillage technology model for the previous crop remain high crop harvest The mechanical of subsoiling spring seedbed strip rotavator fertilization planting. (2) central arid zone areas without supplemental irrigation conditions , the production of food crops should not be implemented stubble no-tillage and rotary two conservation tillage technology processing . ( 3 ) the southern mountainous suitable for winter wheat conservation tillage technology model for the previous crop remain high crop harvest mechanical subsoiling fall seedbed strip rotavator fertilization planting . 3 in Ningxia accelerate the promotion of conservation tillage technology , should do a good job , advocacy training, agricultural agronomic combine and social service work .
