Abstract
|
Conservation tillage is proposed based on the sustainable development of agriculture and agricultural farming systems and technology , its ultimate goal is to protect the ecological environment , effective use and conserve resources, and improve agricultural production capacity and profit margins , and improve the quality of the environment and achieve sustainable agriculture development. The Experimental Study of Inner Mongolia Agricultural University self-developed mobile wind erosion wind tunnel and the wind speed automatic acquisition instrument Yinshan Mountain and pastoral ecotone farmland conservation tillage surface , measuring the variation of wind speed , wind erosion , and other parameters at different wind speeds . Test surface types of wheat , oat , canola and potato plowing bare land . Derived by the analysis of the test data , the stubble surface sediment discharge height relations conforms to the law of the high - order polynomial function (Q = aV5 bV4 cV3 dV2 eV f), according to a logarithmic wind speed with height changes function (V = a bln (x)) law , using MATLAB software related curve fitting , data analysis, up 47.2 percent increase in farmland under conservation tillage surface anti- wind performance than traditional farming farmland surface . This study is not only to improve the theoretical system of Farmland Soil Erosion control techniques , to further promote the application of local farmland wind erosion control technology to provide a theoretical basis and technical basis , and to explore a practical and effective Preventing Soil Wind Erosion and achieve sustainable agriculture the development has a very important significance .
