臨沂翻譯公司關(guān)鍵字：to promote the application of advanced afforestation technology. Such as dry eco-forestry techniques, mulching breeding techniques, technology, and sustainable forest pests without cutting poplar root grafting, high-quality yellow Marshal Cultivation technology. For many of our actual mountain nine years of drought, especially in areas where conditions permit such pressure to promote attention to the sand to plant trees nursery techniques. Pressure field in the arid mountains of sand is mainly used for cultivation of melons and vegetables. Although less used to plant trees, but the effect is very good, especially in mountainous areas northwest of the case nine years of drought have taken a good applicability of the technology. Pressure field has a good sand Xushuibaoshang effect. "After sanding, a lot of ground to form large pores, water easily seeped into the soil, sand soil Tianzeng Tian Tian moisture penetration than 9 times." (1) Meanwhile, the sand covering, cut off the capillary contact, to prevent the soil by wind blowing the sun, reducing evaporation, soil evaporation field 4.1 times higher than the sands. Pressure sand can increase soil temperature, specific heat of sand is mainly small, day by sun drying, easy to increased temperature, the soil under the sand also received a greater amount of heat. Sand and is a poor conductor of heat, heat the soil can hinder the outward diffusion. Therefore, the use of pressure in the arid mountains of sand to plant trees nursery, especially in nursery trees on barren hills and slopes with a high survival rate.(2), to promote conservation tillage technology. Conservation tillage techniques to straw cover, less tillage and surface operations mainly composed of conservation tillage techniques, can effectively reduce the phenomenon of the current dust storms occur.
(3), to actively promote modern biotechnology, microbial technology, poisonous weeds, sand, poplar, high-energy organic fertilizer, water seepage film, and the use of polyacrylamide treatment irrigation ditch, to prevent soil erosion and other technical fields. Trees and grass in the desert can use multi-processing technology, coating technology and packaged technology combined approach. The essentials of the technology is the grass roots first with ordinary water or soak for several hours, then use multi-function water treatment plant for processing grass or roots, and then film and bags combining techniques. To improve the desert grass, tree survival rate. The
