Appraisal The Peventing Erosion Effect Of The Intercropping Strips Stubble Cropland With Movable Wind Erosion Tunnel

The trial utilizes of mobile field wind tunnel tests for different types of stubble, stubble height, stubble bandwidth, the arrangement of stubble band and the protection ability of the stubble band , and study the application of uniform design to arrange tests, and come with the best combination for the conservation tillage and conventional tillage bandwidth, such as intercropping, the stubble for the width of 2m, stubble height of 20cm with the naked oats stubble bandwidth for the same fields traditional farming for the sediment discharge 0.0865. By changing the wind tunnel and conservation tillage with different angles to simulate the blowing wind erosion, the study found that wind conditions in the sediment yield in different ways as follows: 3m conservation tillage is less than 1.5m + 1.5m stubble tillage of 3m stubble intercrop conservation tillage. The protective effect of vertically arranging the bandwidth and the wind is superior to other angle arrangement. By covering up the erosion site to determine the way of wind on intercropping in traditional farming strip of farmland in line with the high-level wind erosion polynomial distribution of bandwidth, in the traditional farming with the existence of the horizontal wind erosion of the value of the volume, it offers the basic evidence for potatoes intercropping in a proper distance and bandwidth.
