Preferably, in stepb, described major ingredient is at least selected from one or both in mud fertilizer, turfy soil.
Preferably, in described greening method, spray described slurry by hydraulic spraying seeder.
Based on technique scheme, advantage of the present invention is:
The invention provides a kind of greening method being applicable to arid biogeographic zone, the method, while supply plant seed adequate water, additionally provides sufficient nutrient, and effectively can resist the harassment of dust storm, also a saving water resource further.
Embodiment
Below by embodiment, technical scheme of the present invention is described in further detail.
The invention provides a kind of greening method being applicable to arid biogeographic zone.In the present invention, following several material composition is related generally to: the major ingredient of water-loss reducer, crosslinking agent, strengthening roots agent, Activator of seed, slow-release compound fertilizer, parcel seed and plant seed.
Described water-loss reducer be at least selected from polyacrylamide, starch graft polyacrylate and lignin grafted polyacrylamide one or more.Water-loss reducer has the function repeatedly absorbing water and release water, and in the process absorbing water, water-loss reducer utilizes its network character can absorb the moisture exceeding the hundreds of even more high power of own wt; In the process of release water, water-loss reducer utilizes again this characteristic energy slow releasing moisture to supply plant utilization, meets the long-term needs of plant growth to moisture.Final water-loss reducer can slowly be decomposed into water, carbonic acid gas, ammonium nitrogen, and to soil and groundwater without any pollution, very environmental protection.
Described crosslinking agent be at least selected from starch, dextrin, acrylonitrile, acrylic acid and methacrylic acid one or more.Crosslinking agent mixes after-applied on soil with water-loss reducer, can form one deck membrane structure at soil surface, this membrane structure can effectively reduce soil water evaporation amount and soil heat scatters and disappears, and effectively keeps the moisture in soil and soil heat capacity.
Described strengthening roots agent is algal polysaccharides class material, this material effectively can promote plant root system development, expand the contact area of root system of plant and soil, increase the sorbent surface of root system of plant to moisture and nutriment and amass, and then raising plant is to the absorption of moisture and nutriment.
Described Activator of seed be at least selected from polyethylene glycol, salicylic acid one or both.Activator of seed is mainly seed Osmolyte regulator, and this substance effectively improves germination vigor and the germination rate of seed.
