Development Of Characteristic Forestry And Fruit Fertilization Decision-making System Platform In Xinjiang Based On WebGIS

Xinjiang Pyrus brestschneideri Rehd is known as the "king of fruit" in the specific natural conditions of Korla. Pyrus brestschneideri Rehd has excellent quality in delicate pulp and fragrant flavor. In order to improve the yield and quality of pear, the different fertilization treatments on growth and yield related experimental were studied to explore the influence factors of Pyrus brestschneideri Rehd, and a large number of models and parameters of soil fertility were obtained. In order to apply these research results to the actual production, in this paper, Pyrus brestschneideri Rehd cultivation area in Korla was taked as the study area. The Pyrus brestschneideri Rehd fertilization decision-making supporting system was developed by C# inserting Arc GIS Server component into the Visual Studio development environment and combining the techniques of database and resource sharing technique based web. The soil data of Pyrus brestschneideri Rehd orchard and related parameters were used in the model. The function and structure,which were connected with the database, the fertilization model and implementation of the system, were discussed.The system contains organic fertilizer, soil testing fertilization and nutrition diagnosis.It aims at improving soil fertility and solves the actual production problem of fertilization of Pyrus brestschneideri Rehd whit important guiding significance and practical value. The structure and the functional design of this system and the construction of database and fertilization model were discussed.The technology of soil testing fertilization and nutrition diagnosis have been integrated into this system.The application of the system, in order to carry out a large area of soil fertilization technology, has provided technical support.The focal point of this thesis contents:1. The query and management of soil nutrient data were realized by technology of GIS. It takes soil nutrient in the data as the foundation to establish the spatial database and attribute database of Pyrus brestschneideri Rehd soil testing Fertilization decision-making system.2. It takes nutrient balance fertilization technology as the theoretical guidance. The fertilization model of this system was built with actual situation of production. The application modules were implemented by algorithm. On the basis of GIS, the fertilization technology and nutrition diagnosis technology were integrated into the system. It expands the function and improves the practicality of this system.All of these technology are intended to realize the Pyrus brestschneideri Rehd soil testing fertilization decision-making system based on Web GIS.
