Research On The Maintenance Strategy Of Natural Grass Football Field Based On The Force Characteristics Of The Game

With the release of the high-profile "over all plan for the reform and development of Chinese football",it points out the direction for the future development of Chinese football.Football is a worldwide sport with wide influence.It is of great significance to improve the national quality,enrich the spiritual and cultural life,develop the sports industry and realize the dream of sports power.Football field facilities are the material basis and necessary conditions for the development of football,but at present,the existing football field facilities in China do not meet the needs of the masses of football.In order to ensure the effective supply of football fields,consolidate the foundation of football development,popularize football and improve the level of football,the national development and Reform Commission,the General Administration of sports,the Ministry of education and the inter ministerial Joint Conference Office of football reform and development of the State Council(China Football Association)jointly prepared the notice on printing and distributing the national football field facilities construction plan(2016-2020)(Fgss [2016] No.987).However,the football field management strategy in China is not satisfactory,and the related research in this field is less.The purpose of this study is to provide scientific theoretical basis for professional maintenance personnel of football field lawn,and improve the use efficiency and service life of natural grass football field.By using the methods of literature,mathematical statistics and experiment,this paper takes the stadium of Tianjin Institute of physical education as the experimental site and the students of football as the experimental objects.Through the arrangement,calculation and analysis of the technical movements of walking,running,jumping and shoveling in the game,the force distribution map of the site is made,and the following conclusions are drawn:1.After a match,the damage degree of grass in different areas of football field is different,the damage degree of grass in forbidden area and midfield area is more serious;the damage degree of grass in left and right areas of midfield is moderate;the damage degree of grass in four corners of football field is less.2.In light trampling area,in addition to timely watering after the competition,in order to keep the lawn in good use,it is necessary to trim the lawn.3.In addition to watering and pruning necessary for maintenance,in order to prevent soil hardening,drilling operation should be carried out in the moderate trampling area.After drilling,it is covered with sand and then suppressed.4.In severe trampling area,the site should be inspected in time to repair the damaged turf.Fertilize in time after replanting,and then water.
