摘要
本文分析了甘肃中部旱作农业开发潜力及限制因素,从充分发挥该区旱作农业潜力看,粮食基本自给完全可能实现,但不利因素多,开发难度大。因此,开发中应重视:兴修水平梯田,优化耕地质量;增加物能投入,实行精耕细作;强化农牧结合,改革种植制度;扩大绿色植被,保护土地资源。
This paper analyses the constraints in explorating farmland productivity potential in the rainfed agriculture in the middle part of Gansu province. We consider that rainfed agriculture holds great potential in this area, and that food self-sufficiency,can be entirely achieved, but there are many unfavourable factors that bring about great diffifulty in exploration or development. The major countermeasures for exploration are as follows: construction of level terrace lands,optmumization of farmlanl quality, increase of material inputs,implementation of intensive-farming, intensification of the combination of agriculture with animal husbandry, reform of farming system, enlargement of green vegetation cover and conservation of land resources.
