Description
Technical field
The invention belongs to the method for improving desert, specially refer to a kind of method of improving plant planting desert.
Background technology
China is big, one of wide, that harm the is heavy country that distributes of desertification in the world and desertification area, and serious desertification of land, desertifying is threatening the sustainable development of China's ecological safety and economic society, threatens the survival and development of the Chinese nation.Desertification land present status: 2004; Desertification soil, the whole nation gross area is 263.62 ten thousand square kilometres; Account for 27.46% of territory total area, be distributed in 498 counties (flag, city) in Beijing, Tianjin, Hebei, Shanxi, the Inner Mongol, Liaoning, Jilin, Shandong, Henan, Hainan, Sichuan, Yunnan, Tibet, Shaanxi, Gansu, Qinghai, Ningxia, Xinjiang 18 provinces (autonomous region, municipality directly under the Central Government).Sandy land present situation: by 2004; Whole nation sandy land area is 173.97 ten thousand square kilometres; Account for 18.12% of territory total area, be distributed in 889 counties (flag, district) of 30 provinces (autonomous region, municipality directly under the Central Government) except that Shanghai, Taiwan and Hong Kong and Macao Special Administrative Region.Two of desertification and sandy lands close 45.58% of the total face in territory that accounts for; Cause the living space of the Chinese nation dwindling; The annual direct economic loss that causes because of desertization is up to 54,000,000,000 yuan; Serious restriction arid area continuous development of society economy also becomes nationwide great ecological environment problem.Cause the main cause of desertification of land and desertification to be, the long-term transition exploitation of people and irrational land resources of utilizing, and do not go to recover to build and be ignorant of the consequence that scientific management causes.On-the-spot investigation for many years and practice, desert have abundant groundwater resources, and because of the influence that receives the external factor factor has the constancy and the travelling performance of good water conservation, this is the advantage of control of desert restore vegetation.Because of the desert has extremely strong permeability and mobile performance, evaporation discharge is big, does not have soil production function, not water conservation, do not protect fertile characteristics.At present, plant seeds by airplane kind grass, machine sowing, people's work post grass receive the harm to seed such as worm, bird, mouse, rabbit again, and it is alive that the sand bed surface does not have confining bed herbage to be difficult to into, with this scheme of thought design of innovation.
Summary of the invention
The present invention is intended to overcome the deficiency of prior art, and a kind of method of improving plant planting desert is provided, and is fit to the improvement in dissimilar deserts, desertification soil.
The method of improving plant planting desert of the present invention, realize through the following step:
A, nascent phase: with stir in the ammonium molybdate of the fused calcium magnesium phosphate of the liquid film of 140～170kg, 0.6～8kg, 0.01～0.2kg and the water that this family of 0.4～5kg nitragin joins 800～1300kg, dissolving; Adding 4～50kg leguminous forage seed again stirs; Sow on one hectare sand ground, seal to prohibit and herded 3～5 years;
Perhaps,
On one hectare of sand ground, sow the leguminous forage seed of 4～50kg earlier; Again with stirring and dissolving in the ammonium molybdate of the fused calcium magnesium phosphate of 140～170kg liquid film, 0.6～8kg, 0.01～0.2kg and the water that this family of 0.4～5kg nitragin joins 800～1300kg; Be sprayed at equably on the sand ground, seal to prohibit and herded 3～5 years;

This family nitragin that adds in the above-mentioned a step is to confirm according to planting the leguminous forage that goes into.
As further improvement of the present invention, 7～30kg gramineous forage grass seed is sowed on sand ground, spray the liquid film of 140～170kg more equably.
As further improvement of the present invention, place the liquid film of 140～170kg to stir in 7～30kg gramineous forage grass seed, sow on sand ground again.
The liquid film of being mentioned in the present patent application; Be public technology; See that publication number is that CN1459471, name are called the open source literature of multifunction degradable black liquid state mulch film, it has following function: solved grass seed and avoided separated evils such as worm, bird, mouse, rabbit, solved again sand ground not water conservation, do not protect the fertile grass of planting and be difficult to into problem alive; Realize recycling economy, improve the ecological environment; Having heat absorption heats, preserves soil moisture, keeps a full stand of seedings, prevents erosion again and effect such as tackling quicksand; Have stronger adhesive capacity, can the grains of sand be coupled to the aggregate structure body, reduce wind erosion, recover the sand ground soil function; Can liquid-state mulch film be decomposed into fertilizer through photosynthetic and microbial action, strengthen sand ground fertility and moisture holding capacity, with after turn in the pressure sand ground, can become the sand ground modifying agent.
Leguminous forage contains higher protein and calcium, accounts for 18%～24% and 0.90%～2% of dry matter respectively, and the content of other mineral matter elements and vitamin is also higher.Another characteristics of leguminous forage are to have a root nodule, and the free nitrogen in can fixed air increases the nitrogen substance in herbage protein content and the soil, thus leguminous forage satisfy domestic animal protein needs and increase soil fertility aspect have very significant values.The major defect of leguminous forage comes off when being the leaf drying easily, and nutrient loses easily during the modulation hay.The hard seed rate of leguminous forage seed is higher in addition, will carry out certain processing during sowing.The leguminous forage protein content is higher, and soluble sugar content is less, is difficult for ensiling.As with the plant mixed silage that is rich in sugar or add the ensiling agent, also can produce good ensiling product.Leguminous forage mainly contain red clover, Bai Sanye, alfalfa, common vetch, vetch, chrysanthemum lupine, white sweet clover, sweet vernal grass wooden slippers, sainfoin, three leaves, crowtoe, prairie milk vetch, Chinese milk vetch, khuskhus and butterfly beans etc.
Gramineous forage grass is rich in nitrogen free extract, and the content of crude protein is 10%～15% in dry matter.Though the nutritive value of gramineous forage grass is not as good as leguminous forage, its good palatability does not have bad smell, and domestic animal is all liked to eat very much.The advantage of gramineous forage grass is to modulate easily hay and preservation; In addition, anti-trample power and the regeneration capacity of gramineous forage grass are strong, fit for depasturing and repeatedly cradle utilization.Gramineous forage grass mainly contains English ryegrass, hybridization perennial ryegrass, Italian ryegrass, Annual Ryegrass, Festuca Arundinacea, fescue grass perennial ryegrass, the chewing fescue that crawls, halymenia dentata, timothy grass, meadow fescue, wheatgrass, kentucky blue grass, awnless brome, African speedwell, Sudan grass, Bermuda grass, napier grass, comfrey, meadow fescue etc.
After sand ground sprays the multifunctional liquid degradative plastic film, form organic physics barrier layer together, cut off and the atmosphere exchange process, suppress scattering and disappearing of water evaporates and fertility, improve temperature, humidity in the sand ground.Reduce the salt content in 0～50cm sand ground, improve sand ground liquid manure, promote herbage multiple fast long to the upper strata conveying capacity.Liquid film sprays degraded gradually in back 40 days, is degraded to fertilizer in 90 days, does not have secondary disaster.Have the sticking granular structure of the sand ground of enhancing, increase fertility and moisture holding capacity, improve micro-ecological environment in the sand ground, prevent that grass seed from avoiding separated evils such as worm, bird, mouse, rabbit, the fixing and revegetation to drift sand has the double action of chemistry and biological sand control.
The method of improving plant planting desert: the availability in soil is increased; Soil obtains sufficient water and nutrient; The large tracts of land forest land can provide the source of forest, keeps the forest rate of growth greater than rate of exploitation, and forest provides the biological use of more oxygen merit and assists to reduce and warms up phenomenon; The area that the windproof protection of forest makes the part desertization reverse can be built building again, increases the volume and the utilization rate in soil.
