黑龙江省西部农牧交错区保护性耕作模式研究

Study on the Conservation Tillages Pattern of Agro-pastoral Zone in the West of Heilongjiang Province

由于采用传统的草原改耕地、过度放牧等耕作方式,致使黑龙江省西部农牧交错区的土壤大面积退化、水土流失严重,导致了生态环境的恶化,实施保护性耕作是改变这种现状的有效手段。通过对传统耕作模式和保护性耕作模式进行对比研究,提出了农牧交互区中农业区和草原区适合采用的保护性耕作技术模式,为未来农牧交错区保护性耕作模式发展方向提出了合理化建议。

The traditional tillage method such as grassland to farmland and over grazing were adopted, which lead to large area soil of degradation and serious soil erosion in the west of Heilongjiang and deterioration of ecological environment, and the conservation tillage was an effective way to change the current situation. This paper compared the traditional cultivation mode with conservation tillage technology model,and proposed the conservation tillage technology models to fit agricultural district and pastoral region respectively. The reasonable suggestions were proposed for the development direction of conservation tillage technology model in agro-pastoral zone.
