Abstract:
Taking Taobei District of Baicheng in the west of Jilin province as the research area. Nine indexes about the main body's approval factor and the agricultural sustainability factor were selected to establish the suitability evaluation system of dry land corn cultivation technology model. The data of nine indexes come from the measured data and the survey data, and the method of Projection Pursuit was used. The results of evaluation showed that among the four straw mulching modes, four straw mixing modes and two conventional modes adopted in the study area the "no tillage + straw rough crushing and returning to row mulching" was the most suitable model to be promoted and applicated in the study area. The main advantages of this model were the highest ratio of production to investment, the least labor, the lower operating cost and long-term straw mulching can improve soil nutrients and physical and chemical properties.
