小杂粮保护性耕作技术探讨

Protective cultivation technology research and practice of minor grain crops

总结了我国小杂粮产区存在的干旱、风蚀沙化和土壤肥力下降等问题,比较分析了保护性耕作技术的优势和传统耕作技术的缺陷,提出了建立合理的轮作体系,采用整株覆盖、留茬覆盖等适于北方旱区的小杂粮保护性耕作技术体系。

As our country＇s characteristic agricultural product, minor grain crops has vast market prospects. This paper analyzes existing problem of drought, wind and soil erosion, soil fertility decline; advances the technology system of protective cultivation on minor grain crops; Put forward research ideas and directions in order to solving the problems of research applications. The research has great guiding significance in promoting the standardization of the technology of protective cultivation on minor grain crops, the increase of farmers incomes, the protection of the ecological environment of the minor grain crops producing area, and the realization of the sustainable development of minor grain crops.
