Abstract

Our study focused on the ecological and economical issue that caused by desertification and farming production in Horqin Sandy Land. We use microbial cultivation technique to screen efficient cellulose decomposing microbial flora (NMCel) from the matrix of sand soils and cattle dung. Maize straw and cattle dung (the dry weight ratio is 5∶3) were used to produce organic compound, adding diluted NMCel to accelerate the compound decomposition rate. The organic compound had a good potency of water holding capacity, air permeability, and viscosity after 60 days fermentation. The organic compound was very efficient to rehabilitate bare sand dunes, and it can increase surface soil organic carbon and total nitrogen, and accelerate biological soil crust formation. Take cost and ecological effects in consideration, we optimized the dune restoration method: put the organic compound (1 kg·5m-2) on the bare sand dunes after sowing the seeds of Artemisia halodendron, Lespedeza davurica,Setaria viridis and so like sand-fixing plants, and then cover the organic compound by shadow nets. The field experiment showed that the optimized method increased vegetation coverage from 6% to 26%, improved soil water hold capacity by 24%-47%, and enhanced wind erosion resistance ability by 5.4-8.6 times compared with natural restoration.
