Study On Popularization Of Water And Fertilizer Integrated Sprinkler Irrigation Technology For Saline Alkali Land In Laoling City

Laoling City have total arable land area 1.1 million mu,but the salinized soil accounts for19.45%.The annual yield of wheat and corn in saline-alkali land is only 200-250 kg per mu,nearly half lower than the average level of general farmland.Nowadays,the lack of land,water shortage,and excessive fertilization have severely hindered the sustainable development of agriculture in Laoling City.Water and fertilizer integrated sprinkler irrigation technology can significantly save water,fertilizer,protect arable land,improve the quality of agricultural products.In Laoling saline-alkali land,it is of great significance to study and promote the application of the integrated irrigation technology of water and fertilizer,save the input of agricultural production factors,and improve the yield of crops,so as to improve the level of agricultural development in Laoling.At the same time,development the integration of water and fertilizer is also an important measure to implement the central green development concept,break the resource and environmental constraints,and accelerate the transformation of agricultural structure.It is an inevitable choice to realize the green application of resources and the sustainable development of the industry.This article investigates and studies the origin,geology and soil structure of saline-alkali soil in Laoling City,and expounds the concept,background and significance of water-fertilizer integration and sprinkler irrigation technology.The status quo of planting on saline-alkali land and several irrigation methods were compared and analyzed.The integrated technology of spray irrigation water quantity,frequency,fertilization and soil conditioner application in saline-alkali soil was studied and analyzed.The application of water and fertilizer integrated spray irrigation technology for the salt-alkali land in Laoling City will increase the cost of investment in agricultural facilities in the short term.However,in the long run,this model compares the traditional planting model of large water drilling and throwing fertilization,which can save 73%,83%of water saving,and 34%fertilizer.And by adjusting the frequency of spray irrigation,applying neutral fertilizers and improved agents,reducing shallow soil salt points,increasing the number of microorganisms,improving the ecological environment of the soil,and increasing 100 kg of food per acre of land per acre.It is concluded that the water-fertilizer integrated sprinkler irrigation technology is in line with the current Laoling City is an agricultural planting form that is accepted by the people for the management of saline-alkali land,the development of modern agriculture,and the increase of crop yields.On the basis of the field survey of saline and alkaline land in Laoling City and the research and analysis of the integrated irrigation technology of water and fertilizer.It is of great significance to popularize the integrated irrigation technology of water and fertilizer based on saline and alkaline land with small investment in facilities,low cost of production factors,significantly improving the soil ecological environment and increasing crop yield.Further analyze the problems of technology,technology popularization and technology application of water and fertilizer integrated sprinkler irrigation technology in saline and alkaline land of Laoling City.Put forward countermeasures and suggestions on the problems in actual applications.In this way,it can better promote water and fertilizer integration spray irrigation technology,save resources,protect the ecology,improve the environment,promote income increase,and promote rural agriculture to revitalize.
