The invention relates to the field of afforestation technologies, in particular to a direct-sowing afforestation method for desert haloxylon of arid and extremely arid areas in the growing season. The direct-sowing afforestation method for the desert haloxylon of the arid and extremely arid areas in the growing season comprises the first step of determining afforestation land, the second step of laying drip irrigation pipes on the afforestation land, the third step of performing irrigation before sowing, the fourth step of sowing, the fifth step of performing current-year management after direct-sowing of haloxylon seeds, and the sixth step of performing next-year management after sowing. Compared with an existing afforestation method, according to the direct-sowing afforestation method for the desert haloxylon of the arid and extremely arid areas in the growing season, the survival rate and the retention rate are substantially increased, cost is greatly reduced, afforestation time is prolonged, and the afforestation method is not affected by weather.

The invention relates to a mode of arranging and building main, auxiliary and intercropping host forests for herba cistanches, namely shelter forests against wind and for fixing sand, and belongs to the field of forestry and ecological environment. The forests consist of a main host forest, an auxiliary host forest and an intercropping host forest. The main hosts of haloxylon ammondendrons are arranged in diamonds, wherein an included angle of each two opposite angles of each diamond are 60 degrees; the distance between each two opposite angular vertexes is the tree shadow length of a 2-meter haloxylon ammondendron during sunrise and sunset on the summer solstice in the lunar calendar; one haloxylon ammondendron is planted at each opposite angular vertex; every three adjacent haloxylon ammondendrons form an equilateral triangle; and every four haloxylon ammondendrons form a diamond. The auxiliary hosts of caragana and Chinese wolfberry are respectively planted on two opposite sides of each diamond; and no trees are planted on the other opposite sides. A 0.5-meter periphery of each main host of haloxylon ammondendron is a blank area. Intercropping hosts of nanophyton erinaceum and artemisia stelleriana are intercropped at the blank area of each two adjacent diamonds. Herba cistanche is planted at the roots of haloxylon ammondendrons. The mode has the effects of blocking off and filtering sand wind, reducing a wind speed, retaining sand storm and preventing the generation of cyclones. The mode can be used for effectively controlling desertization expansion, improving the ecological environment and developing a herba cistanches industry.

Through being deplored for multiple years, the method provided by the invention is applied to Qira oasis of the south rim of Taklimakan desert which is extremely arid and the survival rates of different types of economic species averagely reach more than 80%. The whole growth situation of the retrofitted forest belts is good and the protective effects are gradually appeared.

The invention discloses a mechanical seeding method of desertliving cistanche and belongs to the technical field of agriculture crop culture. According to the method, special seeding machinery for the desertliving cistanche is used for furrowing according to a line distance being 2m to 4m, desertliving cistanche seeds are seeded, the furrow width is 20cm to 30cm, the furrow depth is 50cm to 80cm, then, the soil is covered to the position with a distance with 10cm to 20cm from the ground, a water irrigation ditch is remained, and the water irrigation is carried out; and simultaneously, 1 to 2-year-old sacsaoul seedlings are planted according to a plant distance of 50cm to 200cm. The method has the advantages that the one-step completion of the sacsaoul transplanting and the desertliving cistanche mechanical seeding is realized, and in addition, the method is applicable to the sacsaoul transplanted desertliving cistanche mechanical seeding. The inoculation time of the desertliving cistanche is shortened, the labor force is saved, the seeding efficiency is improved, and the desertliving cistanche inoculation rate is greatly improved.

The invention discloses an imitative ecological afforestation method for Haloxylon ammodendron in a desert area of a sandstorm front, belonging to the technical field of plant cultivation. Desert land with a soil water content of 2% and above and a saline-alkali degree of less than 2% is selected as afforestation land. Cultivation belts are dug out along the eastwest trend of the afforestation land before the soil defreezing and plantation. In the cultivation belts, heeling-in ditches for heeling in are dug along the eastwest trend. Then direct-seeding forestation, irrigation, pest control, and enclosing management and protection are successively applied. Cultivation belts are dug out before plantation and afforestation, so that low survival rate and growth rate of Haloxylon ammodendron caused by the fact that weeds compete with Haloxylon ammodendron for water and fertilizer are avoided. At the same time, the original ecology is maintained by keeping certain space between every two cultivation belts and damage to local ecological environments can be prevented. Demands for water during plantation of Haloxylon ammodendron are sustained by the construction of reservoirs. Thus, the transplanting survival rate of Haloxylon ammodendron is remarkably increased to 90% and above in comparison with the traditional transplanting survival rate of about 10%.

The invention relates to a sacsaoul irrigation-free vegetative cover afforestation method for a draughty gravel desert region. According to the method disclosed by the invention, an excavator is used for deeply digging a planting cavity; a planting substrate screening technology can improve plant rhizosphere soil condition; meanwhile, terrain modification is performed so that natural rainfall is re-distributed in the soil to achieve a snow and water accumulation effect, the water content of the sacsaoul rhizosphere soil is changed, the growth of sacsaoul is promoted, the biomass liveweight is increased, and thus the aim of well maintaining continuous existence of an artificial sacsaoul forest for a long time by depending on a natural water resource in the living space is realized. The process is suitable for restoration and rebuilding of an irrigation-free vegetative cover which takes the sacsaoul as constructive species for deteriorated and damaged vegetative covers of the draughty gravel desert regions under an environmental condition that the average annual precipitation is larger than 100mm and snowfall is stable in winter.
