The invention provides a reclamation method of deserts, which utilizes
biomass foam to reforest and reclaim deserts, wherein the
biomass foam has the functions of being degradable, absorbing water, conserving water, stabilizing sand, fertilizing, and continuously absorbing natural rain,
snow water and
dew for a long time, and moisturizing by
humidity. The method is characterized by comprising the following steps of: determining a throwing area and a throwing amount in suitable time according to the
arid and water-lacking degree, a
survival rate requirement of planting grass and trees, and a speed requirement of reclaiming deserts; and throwing, applying and aerially seeding the
biomass foam into the deserts to be mixed with surface sand or be buried; planting grass and threes on the ground. The biomass foam absorbs the water which is manually applied and naturally absorbs the
natural water to moisturize, so that the water is conserved and the sand is stabilized; after the biomass foam is degraded, the deserts are fertilized, the sand is pasted and stabilized, and the sand quality is improved; the water and the
fertilizer which are needed by a
plant growing period are supplied so that the
survival rate is improved and the comprehensive reclamation of deserts by rapidly reforesting in a large area is realized.
