西藏贫困山区土地高效利用技术应用初探

Preliminary Study on Application of Land Use Efficiency in Impoverished Mountainous Areas of Tibet

西藏大部分地区以山地为主,土地细碎化、土层瘠薄、生产方式落后、生产结构单一等问题制约了西藏山地农业的发展。为半农半牧区提供可持续生产设施种植的技术及材料,推广应用种养结合的技术模式,引进农牧业现代装备,利用免耕技术改善山区的农业生产状况,极大提高了山区土地的利用效率,增加了单位土地的产出率。

The development of mountainous agriculture in Tibet is restricted by such problems as the majority of Tibet being mountainous,the land being fine,the soil being barren,the mode of production being backward,and the production structure being single. Though the technology and materials for planting the facilities to sustain the production in the semi-agricultural-pastoral areas of the mountain were adopted,the technical mode of planting and breeding was popularized and applied,the modern equipment of the agriculture and animal husbandry was introduced,the agricultural machinery used for the cultivated land in the mountain area was introduced,the agricultural production situation in the mountain area was improved by using no-tillage technology. The results are that the utilization efficiency of the mountain land is greatly improved,the yield of the unit land is increased,and the income of the farmers is increased.
