As an important reserve cultivated land resource in my country, its development and utilization are of great significance to ensure food security. Aiming at the problems of bare gravel leakage and shallow soil layer in the barren rock beach area, through community simulation experiments, different covering soil structures were set up on the basis of the underlying gravel, and the effects of different covering soil structures on soil physical and chemical properties and crop yield were monitored to obtain Find suitable soil structures. The results show that: when the covering thickness is 60cm, the content of total nitrogen and available phosphorus in the soil reaches the maximum; when the soil bulk density is set to 1.5 g/cm 3 , the content of available phosphorus in the soil reaches the maximum. The content of available potassium increased with the increase of soil bulk density.
