农牧交错带地区发展保护性耕作的意义与前景

Discussion on the applied prospect of conservation tillage in agro-pasture ecotone

在系统总结保护性耕作技术的内涵、技术内容和类型的基础上,阐述了保护性耕作保土、保水、提高土地生产力、增加农业效益的重要作用,并根据北方农牧交错带的实际情况,从气候、土壤、农作物和社会因素四个方面对技术的可行性进行了科学的分析,认为保护性耕作技术在农牧交错带地区应用前景广阔,但社会经济因素将是制约保护性耕作技术应用的重要因子。加强配套技术的研究、增加资金的投入以及加快农民观念的转变是农牧交错带地区深入开展保护性耕作技术推广与应用需要重点解决的问题。

Soil wind erosion has been the rounding environment in agro-pasture ecotone main factor that influences the agricultural development and surareas. Conservation tillage is the key technique of resisting and controlling soil wind erosion of farmlands. Carrying out the research of application and extension of conservation tillage in agro-pasture ecotone areas is of profound significance. The paper makes a comprehensive analysis on the applied prospect of conservation tillage in agro-pasture ecotone based on the study of the existing problems and the limiting factors. It is discovered that the social-economic conditions are the main limiting factors that influence its application and extension. Therefore, it is necessary to strengthen the study of key techniques, to increase the input of capital and to change the traditional idea of farmers so as to accelerate the application of conservation tillage in agro-pasture ecotone areas.
