September 4,Shaanxi Provincial Department of Science and Technology organizes relevant experts in Yulin,By Shaanxi Real Estate Development Services Corporation、Identification of the scientific and technological achievements of the "Core Technology Research and Engineering Demonstration of Soil Formation of Mu dafabet casino mobile appUs Sandstone and Sand Compound" jointly conducted by the Institute of Geographical Sciences and Natural Resources of the Chinese Academy of Sciences and Xi'an University of Technology after three years。Experts from the appraisal committee carefully reviewed the relevant materials、After listening to the project report and conducting on-site inspection and demonstration,Consensus,The project has been fruitful,Sufficient theory,Advanced technology,Original and important promotion value,Reached the international leading level of similar projects。

Mu Us Sandy Land is the collective name for the sandy land along the Great Wall in northern Shaanxi and in the southeastern part of the Ordos Plateau,Total area is 7.84 million hectares。In the area,Arsenic sandstone and sand are both called "two evils",arsenic sandstone,hard as stone without water、Soft as mud when exposed to water,Loss of water,Known as “environmental cancer”;The sand structure is loose、Leaking water and fat,Unable to form a granular structure of soil。Therefore,These two substances are the “culprits” leading to the ecological degradation of land resources。The appraisal committee believes,This project focuses on land development and improvement、Strategy to resolve the contradiction between economic development and land resources and achieve coordinated development of man and land,Use experiments、Test、Observation、Complete set of technical methods such as simulation,Material properties of arsenic sandstone and sand widely distributed in Mu Us Sandy Land、Conducted in-depth and systematic research and engineering demonstration on cementation and its soil-forming core technology,The following innovative results have been achieved: First, the complementarity of the two material structures of arsenic sandstone and sand in soil formation was discovered for the first time,Systematically carry out experimental research and field tests dafabet loginon arsenic sandstone and sandstone soil formation,Proposed a combination formula of arsenic sandstone and sand suitable for the growth needs of different crops;The second is based on experimental and field trial research,Proposed an efficient utilization model of water and soil coupling in ecologically fragile areas;The third is to integrate and condense the soil formula technology of arsenic sandstone and sand、Field configuration technology、Planning and Design Technology、Large-scale rapid land reclamation technology、Five technologies including water-saving and high-efficiency technology,Having formed a systematic and complete technical system for soil formation from arsenic sandstone and sand;Fourth is the innovative implementation of standardization、Large-scale soil formation project,Changing the "two evils" of arsenic sandstone and sand into "one treasure",Successfully realized the resource utilization of sandy land,A new comprehensive land management model integrating water-saving, efficient, high-standard farmland construction and modern management in the Mu Us Sandy Land has been formed。Project embodies theoretical research、The characteristics of close integration of technological innovation and engineering practice,After a multi-step series of experimental research and engineering demonstration,In science、Actively promote technological achievements on a normative basis,Achieved significant economic gain、Social and ecological benefits,Laid an important foundation for innovative sandland remediation and utilization models and the development of modern and efficient agriculture。

Shaanxi Real Estate Development Services Corporation overcame many difficulties in Dajihan Village, Xiaojihan Township, Yuyang District, Yulin City and Mengjiawan Village, Mengjiawan Township,Use this technological achievement,The combination of arsenic sandstone and sandy soil has achieved remarkable results in land development dafabet mobile appand remediation。Among them,Land improvement in Dajihan Village,Starting from March 2010,Completed in October of that year,Added more than 2,327 acres of cultivated land to Dajihan Village。April this year,After intensive land management by Dadi Seed Industry,It is expected that the average yield of potatoes planted for the first time will reach more than 3,000 kilograms,Double the potato yield grown on the village’s cultivated land。
