土地是农业生产之本,保护土壤、培肥地力,提高土地的生产能力,运用保护性耕作技术是农业生产可持续发展的关键。保护性耕作技术,是在农作物收获后,不再进行传统的耕翻作业,而是直接进行施肥播种;与农作物秸秆覆盖还田技术、机械深松技术以及病虫草害综合防治技术共同构成了一套完整的保护性耕作技术体系,是对我国农业生产传统工作模式的重大革新。通过近几年的实践证明,河套地区地膜重复利用免耕栽培技术,具有显著的社会效益、经济效益、、生态效益,具有十分广阔的发展前景。
Land is the basis of agricultural production, protecting the soil, fertilizing the land and improving the productivity of the land. The use of conservation tillage technology is the key to the sustainable development of agricultural production. Conservation tillage technology, after harvesting of crops, no longer carry out the traditional farming operations, but direct sowing of fertilizers; and crop straw mulching technology, mechanical subsoiling technology and comprehensive control of pest, weeds and grass diseases together constitute a The complete system of conservation tillage technology is a major innovation in the traditional mode of agricultural production in our country. Through the practice in recent years, it has been proved that the no-tillage cultivation technology of mulching film in Hetao area has significant social benefits, economic benefits and ecological benefits, and has very broad prospects for development.
