| As one of the main Camellia oleifera producing areas in China,Jiangxi has not paid enough attention to the production of Camellia oleifera for a long time.The management of Camellia oleifera is extensive and the mode of operation is lagging behind.At the same time,the technology tradition lacks scientific and technological support.Low-yielding,middle-low-yielding Camellia oleifera area accounts for a large proportion of the whole province,and the overall age of Camellia oleifera forest is relatively large.In order to explore an effective way to manage agricultural resources accurately and efficiently,and to better realize the acquisition,processing,rational utilization and data sharing of agricultural resources,a set of standardized management information system for Camellia oleifera plantation was established in this paper,and the accurate,efficient and standardized management of Camellia oleifera was expounded.Based on the theory and practice of management information system,this paper makes a detailed and in-depth investigation and Research on the research area,carries out sampling design combined with relevant professional knowledge of land resources,detects and processes the sampling data,obtains accurate soil nutrient data of Camellia oleifera garden,and then designs and establishes a fertilization model of Camellia oleifera.The whole Camellia oleifera garden image is collected by UAV,and the original image is processed and stitched into panorama.At the same time,the interactive function of specific scene is realized by programming XML document in Krpano engine,and panoramic roaming image is made.Using PostgreSQL and PostGIS technology to construct the basic database of the system,combining J2 EE technology framework and open source WebGIS engine,taking JEECG as development platform,on the basis of integrating existing Camellia oleifera resources,production and operation data,a standardized camellia garden management information system with five basic functional modules and higher security level was developed.The main conclusions of this paper are as follows:(1)In this system,the fertilization suggestion of Camellia oleifera is based on the fertilization model of adjustment coefficient method of nutrient abundance and deficiency index,which is accurately calculated by sampling and measuring soil nutrient content.Compared with conventional fertilization,it has more reasonable fertilization structure and fertilizer dosage,reduces unreasonable fertilization dosage,improves crop yield,and promotes agricultural quality and efficiency.Because this fertilization model can get the recommended amount of fertilization according to the measured soil nutrient content and different nutrient requirements of crops in different regions,it is of great significance to popularize the fertilization model.(2)The panoramic roaming view of Camellia oleifera garden is an innovative point of this research.Using Krpano software,panoramic roaming can be made easily and efficiently with low cost.By combining specific scenarios and programming Krpano XML documents,highly customized projects can be developed,and online panoramic production and display platform can also be developed using Krpano tools.The application of panoramic roaming and panoramic video technology in many scenarios,such as real estate,commerce,hotels,tourist attractions,Museum characteristic venues and so on,will make panoramic roaming and panoramic video technology have broad market promotion significance.(3)A simple WebGIS-based management information system for Camellia oleifera plantation in southern hilly areas is designed and constructed.The system has high integration and reusability,friendly interface and accurate analysis,and ensures system security by combining role-based access control mechanism.Based on the system database composed of production investment data and field spatial data over the years,the system realizes the query and statistical analysis of all kinds of data,which has higher practical decision-making guidance significance. |
