Study On Soil Nutrient Composition Of Apple Orchard And Improvement Of Closed Orchard In Tongchuan City

Apple is the first of China's four significant fruits and is a critical fruit crop product and export product in China.The apple industry is also the leading agricultural industry that has endured for nearly two decades in Tongchuan City.The rapid development of the apple industry in recent years has played an irreplaceable role in improving the quality of life of local farmers and the overall industrial-economic transformation in rural areas.With the development of the agricultural economy in recent years and the active role of the Tongchuan farmer benefit policy,the growing field of apples has continued to increase,and the output has increased accordingly.However,there are many restrictive factors that cannot be ignored in the development of the apple industry in Tongchuan City,which restricts the sustainable development of the apple industry,high-tech transformation,carbon free development,and agricultural modernization.The apple industry in Tongchuan is facing many technical problems that need to be resolved.This study analyzes the development of the apple industry in Tongchuan City,explains the problems in the apple industry from the two aspects of fruit tree nutrition and improvement of closed orchards,and proposes corresponding feasible solutions for the industrialization of agriculture Modernization provides guidance for reference.From March 2017 to November 2019,this research conducted a practical analysis and exploration of the problems in the development of the apple industry in Tongchuan City through visits to agricultural departments,field investigations,field experiments,and other methods,and studied the corresponding solutions.As a countermeasure,this study conducted cut-in analysis from two aspects of fruit tree nutrition and the improvement of closed orchards.The results showed that:(1)The soil nutrients in Tongchuan City are relatively poor,and the nutrient distribution ratio is uneven,mainly manifested in potassium and phosphorus.The proportion of elements is too high,while the proportion of organic matter,nitrogen and trace elements is too low.(2)The apple industry in Tongchuan City lacks the concept of extensive application of organic fertilizers,and there is an uneven ratio in the ratio of fertilizer application,and one-sided pursuit of high yield.(3)The serious closure of orchards in Tongchuan City has hindered the product quality and sustainable development of the orchards.Therefore,according to the analysis of the survey results,this study come up with three suggestions for the development of the apple industry inTongchuan City,Such as(1)adjust the proportion of soil fertilization according to the advantages and disadvantages of the congenital soil conditions of Tongchuan City,increase nitrogen fertilizer,trace The application of elemental and organic fertilizers controls the proportion of potash and phosphate fertilizers.(2)Reasonably and effectively apply organic fertilizer,and vigorously promote and improve the application of organic fertilizer in Tongchuan orchards.(3)Use thinning treatment to transform Yuchuan Orchard in Tongchuan City and promote the sustainable development of Tongchuan Orchard.
