- Abstract:

The field survey and indoor analysis were carried out to explore the effect of layout way of and barrier on sand soil properties. Four kinds of sand barrier materials(branch, cotton straw, corn straw and nylon net)were laid vertically and horizontally. The effects of sand barrier on soil properties were analyzed and soil quality were evaluated by soil quality index. The results show that:(1)there were highly significant differences between available nitrogen, available phosphorus, available potassium, pH in the sand barrier areas and those in the control area(p<0.01), significant difference between soil bulk density in the sand barrier areas and that in the control area(p<0.05); soil bulk density and soil available nitrogen are important indicators for monitoring soil quality improvement;(2)the soil quality in the 0—60 cm topsoil in the sand barrier area which has been laid for 44 months, increased by 17.990% on average, and the improvement effect of flat cotton straw checkerboard barriers on the soil quality is the best in the 0—60 cm topsoil which increased by 30.752%;(3)the improvement effect of soil quality in flat layout of sand barriers is more effective than that in vertical layout, especially in the 0—40 cm soil layer where the soil quality increased by 18.437% in the flat layout area of sand barriers, and increased by 6.725% in the vertical layout area. Therefore, the layout of sand barrier in the sand area has an important impact on the improvement of soil properties and the restoration of soil quality.
