摘要
研究砒砂岩与沙复配成土技术在毛乌素沙地土地整治工程中的推广应用。在砒砂岩与沙复配成土技术的基础上,通过勘测、设计,综合考虑项目选址、农田设计、灌溉设计、道路和防护林设计等,将该技术在毛乌素榆林市榆阳区进行了推广应用。运用该技术累计整治规模约2 100公顷,新增耕地约1 573.3公顷。技术的推广应用形成了毛乌素沙地节水高效的高标准农田建设与现代化经营为一体的土地综合整治利用新模式,增加耕地的同时,提高了经济效益,保证了生态环境质量。
The purpose of this study is to research the popularization and application of mixing soils farmland technology of arsenic rock zone and sand in Mu Us Desert land reclamation engineering. On the basic of mixing soils farmland technology of arsenic rock zone and sand, the methods used included investigation and design in Da- jihan of village, Xiaojihan Township, Yuyang District, Yulin City. On the basic of Considering the project site, farmland design, irrigation design, road and shelterbehs design, mixing soils farmland technology of arsenic rock zone and sand was promoted and applicated. The results indicated that 2100 hm2 land in all have been developed, in which there is addition plough 1 573.3 hm2. The research conclued that the popularization and application of this technology formed land remediation advantage of the new model of water-saving and efficient high-standard farmland construction and operating of modernization, at the same time to increase the cultivated land, improve economic efficiency, to ensure the quality of the ecological environment.
