摘要：As a new type of compound soil of soft rock and sand in Mu Us Sandy Land, Whether the texture state can maintain stable development is the primary concern. In this paper, the Mastersizer 2000 laser particle size analyzer method was used to analyze the variation characteristics of particle composition of mixed soil with different volume mixing ratios (1:1, 1:2, 1:5) in field tests from 2010 to 2016.The results show: With the increase of planting years, the content of clay and silt increases, the content of sand decreases, and the texture of the compound soilpresents a benign development trend.with the ratio of 1:1, 1:2 and 1:5 of soft rock and sand compound soil, and the C/F value of the compound soil tends to decrease, and the tillage layer tends to refine, which improves the stability of the compound soil.Therefore, the compounded soil can maintain a good and stable state of development during the utilization period, and it does not need to be compounded after many years.
