摘要

土壤风蚀是中国北方农牧交错带土地退化的主要原因之一。微生物和腐殖酸都能够改变土壤物理性质，可作为抗风蚀的材料有效利用，其抗风蚀效果和经济效果与其他方法有很大的不同。在此基础上通过风洞实验探讨微生物（接种根留菌）处理下和施用腐殖酸肥处理下抗风蚀效应，以及不同处理下的风蚀量对比。从结果分析得出，一方面，通过接种根瘤菌和施用腐殖酸肥料，改良土壤结构来抗风蚀，效果明显。技术易于推广．且成本较低（相对于PAM），另一方面它们能增加土壤肥力．带来经济效益。

Abstract

Wind erosion is one of the main causes of land degradation and one of the most serious problems in the north Ecotone of China.Rhizobia and humic-acid can do better with soil property because it can make the particle bigger

and it will be used as preventing wind erosion availably.The effect of preventing wind erosion and economy are different with other technique

but it has not been studied yet.It will be analyzed the effectiveness of preventing wind erosion with rhizobia and humic-acid based on wind tunnel experiment

and the amounts of wind erosion will be compared with different land type.From the result of analysis

they have some merits.On one hand

it is obvious to prevent wind erosion with inoculated rhizobia and humic acid fertilizer by adding soil particles aggregates

the technique is popularized widely

and the cost is very low(compared to PAM);on the other hand

it can improve the fertility of soil and benefit.
