复种技术在西藏的应用与思考

Application and Consideration of the Effects of Multiple Cropping on Soil Fertility in Tibet

复种是粮食增产最简单直接且行之有效的一种方式。将种地、养地相结合,防治水土流失从而提高土地的可持续发展能力,合理发展复种,充分利用光、热、水、耕地等自然资源。提高资源的利用效率对农业的可持续发展有非常重要的意义。介绍了复种制度对饲草生产的意义,分析了西藏复种制度的潜力条件、复种的经济效益和生态意义、西藏复种发展趋势,最后对西藏复种制度发展模式进行了思考。

Multiple cropping is the simplest,direct and effective way to increase grain production.It combines planting and cultivation to prevent soil erosion to improve the sustainable development of the land,to rationally develop multiple crops,and to make full use of light,heat,water and cultivated land and other natural resources.Improving the efficiency of resource utilization was of great significance to the sustainable development of agriculture.We introduced the significance of multiple cropping to forage grass production,analyzed the potential conditions of multiple cropping system in Tibet,economic benefit and ecological significance of multiple cropping,develop trend of multiple cropping in Tibet.Finally,we took consideration on the development modeof multiple cropping system in Tibet.
