| Against the backdrop of the new normal of China’s economic development,the No.1 Document of the CPC Central Committee has always focused on "issues concerning agriculture,rural areas and farmers".It calls for the construction of modern agriculture,the acceleration of the transformation of agricultural development mode,and the development of modern agriculture featuring efficient output,product safety,resource conservation and environmental friendliness.With the rapid development of information technology,the application of big data system provides opportunities for the development of society in many aspects.Big data applications combined with agriculture and precision fertilization technique,precise management,fertilization,comprehensive utilization of fertilizer resources,improve the utilization rate of fertilizer and effectively solve the non-point source pollution,will inject vigor for agricultural development,ensure good quality and high yield agriculture,is more advantageous to realize enterprise and farmers to reduce costs,increase efficiency,the purpose of provide an opportunity for the development of agricultural materials enterprise innovation.This paper takes the big data system of Guangxi Li Yuanbao technology(group)co.,LTD as the research object,adopts the methods of field research,empirical analysis and questionnaire survey to study the application status and existing problems of big data system in precise fertilization,and puts forward countermeasures and Suggestions on the basis of this.The research results will provide guidance and reference for the improvement of the big data precise fertilization system.The main research results are as follows:1.The force source treasure big data system plays an important role in crop precise fertilization,(1)The system will be precise fertilization technology with large data systems and network geographic information system technology,1.146 million soil samples were collected,4.5 million test packets and so on many soil survey data,have a professional technical support and extensive research data.(2)The system platform is a visual decision platform integrating precise fertilizer distribution,yield prediction,market analysis,benefit analysis and technical guidance.It improves the ability of data management and service by informatization and provides timely,accurate and reliable decision Suggestions based on data information.(3)The system according to the planting area of soil fertility,combination of crops(such as eucalyptus,passion fruit,sugar cane,dragon fruit,mango,banana,camellia,grapefruit,rice,etc.)need to grow and nutrition,and the weather,rainfall,market and so on various data resources,through the integration of the data analysis provide the optimal fertilization scheme,and professional services to guide the agricultural technology.2.Field test results showed that: the quality indexes of sugarcane fertilization formula guided by Li Yuanbao precise fertilization big data system were higher than traditional fertilizers.The actual sugarcane yield increased by 17.26 tons/ha on average,and the output input ratio increased by 0.83 million yuan/ha on average.The average growth rate of sugarcane plant height was 37.31 cm,the average growth rate of stem diameter was 0.07 cm,the average growth rate of sugarcane hammer degree was 0.71%,the average growth rate of sucrose content was 0.9%,the average growth rate of sugarcane juice simplicity purity was 1.34%,and the average growth rate of sugarcane fiber was 1.3%.The big data system of precise fertilization makes agricultural production more scientific and accurate,improves the utilization rate of fertilizers,and provides guidance and reference for enterprises to make decisions on fertilizer used in crop production,so as to realize the purpose of saving costs and increasing income and efficiency of agricultural products for enterprises and farmers.3.There are the following major problems in the construction,use and promotion of the big data system platform of precise fertilization :(1)China’s agricultural informatization is low,the lack of core research and development skills,the construction of technical facilities is relatively backward,and the integration and utilization of resources is difficult.(2)The construction of the big data system for precise fertilization is not perfect,the data collection,sorting,preservation,management and utilization are not paid enough attention to,the data information is updated slowly,the fertilization program is relatively single,and the big data resources cannot play a full role.(3)Limited by infrastructure conditions,farmers used big data to understand and inconvenient,lead to small enterprises to promote the system range and does not reach the designated position,enterprise technical personnel to the big data system application is vague,lead to low level of agricultural technology services,technical guidance does not reach the designated position,farmers could not fully understand the benefits of big data system.(4)The construction and application of the accurate fertilization big data system requires a large investment in scientific research,high cost,shortage of funds,high demand for talents and insufficient personnel reserve.(5)The scope of soil fertility targeted by the big data system of accurate fertilization is relatively wide,and the accuracy needs to be further improved,which results in the market positioning is limited to large customers,the customer base is narrow,and the choice of market development strategy is limited.4.In view of the existing problems,a series of countermeasures and Suggestions for optimizing the application platform are put forward :(1)Government support,make big data a national development strategy,increase support,open data,realize resource sharing,and strengthen the preferential guidance of science and technology,talents,capital and other resources to big data technology in the form of laws and policies.(2)The information data management,link and integration of the precision fertilization big data system should be rigorous and timely sorted out and uploaded to the system to ensure the timeliness of information.Improve and timely update the system functions,effectively help farmers in the process of crop planting and production errors and errors,provide farmers with a more intuitive and effective system effect experience.(3)The application and promotion of the system should be aimed at farmers,and the mobile intelligent big data application system oriented to agriculture should be developed to provide accurate information on the market,policy,life and other aspects of agriculture anytime and anywhere.(4)Strengthen technology and talent cooperation between domestic and foreign universities,scientific research institutions and enterprises.Enterprises should not only pay attention to core technical talents of data management technology,but also pay more attention to training or introducing innovative talents with profound understanding of agricultural development.(5)Deepen the application of the big data system of precise fertilization,closely track the development trend of information technology,further strengthen the investigation and statistics of soil conditions in various regions,improve the accuracy of the system positioning decision,deeply integrate various resources,and enrich the management means and service skills of the system. |
