The Technical Pattern And The Effect Evaluation About The Use Of The Saline And Alkaline Land

The development and utilization of saline land in China is to increase the area of arable land, to achieve sustainable development and an important means of maintaining dynamic balance of the total arable land. Dalate agricultural land as flag banner, of great significance in the development of agriculture, but in recent years, Dalate’s salinization is serious. In the improvement and utilization of saline alkali land, explore a set of technology model in line with Dalate’s actual saline alkali land use, not only can solve the long-standing saline soil improvement is slow, the development and utilization of no start and other practical problems. And to solve the region increasingly less effective cultivated land, cultivated land per capita, problems of food production supply is not sufficient. To vigorously tap Dalate’s cultivated land potential in saline land, increase farmer income, ensure food security of supply, to provide the reliable experience for the development and utilization of Ordos and Inner Mongolia in high latitude saline It is of great significance.Based on the review analysis at home and abroad to develop and utilize the existing salt technology mode, rice cultivation on Dalate’s saline project carried out a detailed investigation and elaboration, and the use of cost-benefit analysis, fuzzy evaluation method, AHP method and comparative analysis of 4 methods from the economic effect.3 the social effect and ecological effect of establish the evaluation index system of saline alkali soil rice planting project implementation effect, using survey data from 47 households and 27 copies of questionnaire were evaluated and analyzed, the results show that the Dalate flag project implementation effect, has certain theoretical and practical significance. On the basis of the order analysis of constraints Dalate’s development and utilization of saline alkali soil factors of rice planting project summary and evaluation and questionnaire, based on the above analysis put forward the future development of planting in saline alkali soil Countermeasures for the further development of rice.
