摘要
通过 30年间对西北的考察 ,分析了该地半干旱区旱地农业的特征、进展与问题。强调该地区在农业发展中应遵循的五个规律性问题 :水肥耦合相互制约的规律、生态适应性规律、农业生态 (生产 )系统开放性规律、农业生产与农村经济有序发展的规律以及农业的集约化与持续化同步发展的规律。提出建议 :种植业→养殖业是一条主渠道 ;大力增施化肥 ;减轻水土流失 ,促进农业持续发展 ;在“水”字上还要大做文章 ;面向市场扬长避短调整结构。
The semi arid region of North West is one of the most undeveloped zones in China, characterized by the closed or semi closed and traditional, extensive, unsustainable farming with very low input and output.Though 33 time′s agricultural investigations in this region by the author of this paper during recent 30 years, several principles of regularity and some concrete suggestions for agricultural intensification and sustainability in the future are presented.
