青島翻譯公司關(guān)鍵字：technology of Shaanxi province, a research unit of the research and development, proven, this technology has successfully solved the sandy area due to drought and grass, the problem of low survival rate of trees.(4), the use of advanced technology to make improvements to the existing Grassy to improve load capacity and water conservation education capacity. In particular, to take effective technology gradually eliminate poisonous weeds and harmful rodents, so that翻譯公司報價 some play a greater protective benefits of Grass. Haiyuan翻譯1000字多少元 County, South China, such as the Grassy Mountains improvement and rodent control problem is very urgent.(5), to further develop the "three fields" in the construction of ecological role. The "three fields" building to construct a high standard of basic farmland, based on the provision of land Curb and deep plowing deep plowing water, fertilizer increased water diversion and water pressure sand combination of engineering measures, biological measures, and tillage combination and to increase investment in agriculture is to completely change the agricultural production conditions and ecological environment, disaster resilience, to maintain long-term stable growth in agriculture, an important measure. Years of testing, proved: in the mountains without a certain amount of "Mita" guarantee, there is no relatively stable food production, in solving the foundation is not solid food and clothing. As long as the grain harvest, the mountain is relatively fast economic development; the other hand, the economic development will be limited. "Mita" construction is forest and grassland, to achieve good ecological environment to ensure that pregnant cycle. Many small mountain as basic farmland, sloping yield is low, only by a single food production to maintain a lower standard of living, long-term extensive cultivation could not escape the vicious circle of passive situation. Food production and forestry, animal husbandry struggle to make the goal of returning farmland to forest, animal husbandry and difficult to achieve, even if temporarily step down, it is difficult to consolidate. Many advanced typical examples prove, forest and animal husbandry, to achieve environmental objectives must be as a virtuous cycle of agriculture, forestry, animal husbandry, the struggle to resolve the contradiction of progressive realization. The only way to resolve this contradiction is to take the "soil improvement wins high to high-yield farmland protection, to promote grass farmland to forest and grass Xing
