Construction Of Information Platform For Resource Utilization Of Organic Waste From Agriculture And Forestry

As a large agricultural country,China generates a large amount of organic waste from agriculture and forestry every year,mainly crop straw and livestock manure.The way of resource utilization of these organic wastes is based on fertilization,especially composting technology,which is one of the important grips for sustainable development of green countryside.However,due to the lack of awareness of rural residents on the rational use of organic waste and their limited access to these technologies,the efficiency of resource utilization of crop straw and livestock manure is not high.With the continuous construction of agricultural informatization in China,some advanced knowledge and technologies can be reached by more efficient informatization tools to the people involved in agriculture.The main purpose of this thesis is to convey the relevant technologies to the farmers through the construction of the information platform of organic waste resource utilization in agriculture and forestry.In this thesis,we collected the requirements for the development of the information platform through a survey of farmers,and built an information platform with six sub-systems using We Chat applet development tools as technical support.The main contents of this thesis include the following four aspects:(1)measuring and investigating the data and information related to the resource utilization of organic waste and establishing the basic database of organic waste utilization;(2)collecting,summarizing and analyzing the platform requirements through research,and carrying out the platform prototype design.Including the overall framework and process design of information system,detailed design of each sub-system and detailed design of database;(3)build the information platform and realize the main functions of the platform.Including: browsing,retrieving and publishing information such as text,pictures and real-time images;uploading and downloading platform data,editing and modifying data,data statistics,permission management assignment,viewing logs and other background management functions;compost fermentation parameters calculation.(4)Application verification of the information platform.The results of the thesis are as follows:(1)A database of physical and chemical indicators of organic waste materials was established,divided into nine categories with 84 data;a database of standards related to organic waste utilization was established,divided into four categories with 26 standards;a database of enterprises related to organic waste utilization was established,and 346 pieces of organic material decomposers were collected.(2)The information platform for resource utilization of organic waste from agriculture and forestry was designed and realized,which contains six sub-systems.They are: composting technology list,related standards,composting visualization,team information,product display and application,and composting parameter calculation.(3)Application tests were done on the system from different angles,and each function ran normally and used smoothly;The composting test was conducted with the composting recipe calculated by composting parameters,and the fermentation in the pile was relatively stable and adequate,and the finished composted products met the testing standards.It was verified that the compost recipe calculated by the software was effective.
