| 摘 要： | 根据目前保护性耕作的技术规范,选择留茬高度为30cm,研究保护性耕作带状间作的抗风蚀机理。利用可移动式风蚀风洞在野外定点原位试验,研究了在不同风速、植被覆盖度分别为45%,76%和90%情况下的近地表土壤抗风蚀能力,分析了影响土壤风蚀因素,提出了具体技术措施,从而为在干旱和半干旱寒冷易沙化农牧交错区实施保护性耕作,有效抑制土壤风蚀及大风条件下的农田地表起沙扬尘提供一定技术依据。

| Abstract: | Based on the current technical specifications of conservation tillage,we initially choose the stubble height of 30cm,and study the strip intercropping mechanism of anti-wind erosion of conservation tillage. Firstly,we use the movable wind tunnel to do the fixed in situ experiment in the wild. Secondly,we study the near-surface soil anti-erosion ability in the case of different wind speed and vegetation cover,respectively,45% ,76% and 90% . Thirdly,we analyze the impact of soil erosion factors and put forwar... |
