西部大开发中耕作制度的发展对策

西部大开发为西部农业的发展带来了机遇,同时也带来了挑战。西部农业落后,农业经济需要更大的发展。退耕还林还草使耕地数量减少,为西部农业的发展提出了新问题。只有改革现有的耕作制度,提高单位面积耕地生产力并调整种植结构,才能促进西部农业经济的发展和确保退耕工作的顺利进行。在耕作制度上,应大力推广少、免耕技术,发展节水农业;调整种植结构,实行三元化农业;培肥地力,加强田间管理,提高作物栽培水平,实行保护地栽培,发展设施农业。

Countermeasures of Tillage System in the Western Development

The western development will provide an opportunity and challenge for western agriculture. The development level in western agriculture is very low and should be raised in a great degree. With the return for planting trees and grasses, the area of farmland will be reduced. If the productivity of unit farmland area is increased and the crop structure is adjusted, the development in western agriculture will be further promoted and the farmland return will be successfully carried out. Therefore, the countermeasures in the tillage system should include: spreading greatly the reduced tillage and no-tillage technologies to develop water saving agriculture, changing the crop planting structure to get a three-unit agriculture, increasing the fertility of soil and strengthening the field management to increase crop cultivated level, carrying out crop protective cultivation to develop a installation agriculture.
