The Key Technology Research on Automatic Monitoring and Remote Controlling of Water and Fertilizer on Banana

Abstract

This paper discusses the necessity and importance of technology of drip irrigation of integral control of water and fertilization. Firstly, research situation at home and abroad of agricultural information and technology on water and fertilize controlling, agricultural production management, environment monitoring and platform for agricultural expert system is presented in this thesis. Secondly, Key technologies on automatic monitoring and remote controlling of water and fertilizer on banana are analyzed emphatically, which contains four aspects: key technology of banana soil parameter automatic monitoring, key technology of banana growth parameter automatic monitoring, key technology of the model of water and fertilizer regulation, and key technology to implement system of automatic monitoring and remote controlling of water and fertilizer on banana. At last, the paper summaries that the technology of drip irrigation of integral control of water and fertilization will be improved continuously with dramatic development of information technology, which can also lead to great changes in agriculture industrial advantages and benefits. Introduction Technology of drip irrigation of integral control of water and fertilization is one of the most important measures to improve water use efficiency under protected cultivation, which is an important technology to save water, economize fertilizer and protect the environment. In order to improve banana automation level, water and fertilizer-saving efficiency and promote the development of agricultural modernization, we should bring greater attention to agricultural information techniques, and enhance the research and application of advanced intelligent control techniques and decision-making sustainment. The research on the system of automatic monitoring and remote controlling of water and fertilizer on banana helps to achieve standardized management of banana orchard, save resources, improve work efficiency and eliminate unstable yielding. These works can fulfill the goals of water and fertilization management efficiently and quickly. The extension and application of these techniques successfully in large areas has a very far-reaching significance for both China and the rest of the world. Research Status The application of information techniques in agricultural production management is more and more widespread. Peets S et al. have established farm management information system applied for agricultural production management on private farms. Farm financial condition, characteristic farm products and market information can be released over the network. The system has functions of information acquisition, expert decision and intelligent farm machinery management based on spatial information application technology. Because of the short history, starting late and insufficient experiences of agricultural modernization in China, the overall level of in agriculture irrigation is lower and the condition of environmental monitoring is poor. It is imperative to improve and raise the technique in drip 3rd International Conference on Mechanical Engineering and Intelligent Systems (ICMEIS 2015) © 2015. The authors Published by Atlantis Press 398 irrigation of integral control of water and fertilization. Up to now, there are many domestic studies on it, including ecological balanced fertilization model, field precision fertilization decision support system, water-saving irrigation, field intelligent irrigation control system, and so on. These studies relate to wheat, rape, tomato and cucumber. But the automation and the identify result is not very good. Lansheng Deng et al. have studied technology of drip irrigation of integral control of water and fertilization on banana. According to the number of banana leaves, fertilizer application and stage are determined in banana entire life cycle. After fertilizer is dissolved in water, it will be taken directly to the plant root zone through drip irrigation system by irrigation water. Developing modern agriculture is the inevitable choice to quicken the Chinese agriculture development. It is also a fundamental way to solve our three rural problems: peasants, agriculture and rural areas. Space technology, mobile internet, Internet of Things, automation technology and other information technology are fully applied to agricultural production management, including information monitoring, expert decision, intelligent management, and prediction and forecasting. The application of agricultural information technology will step into a period of great development. Key Technology Key technology of banana soil parameter automatic monitoring. Using sensor technology, the measurement of soil moisture, soil nutrient, air temperature and humidity can be realized to measure rapidly and accurately. Using GPRS, hardware inter-face technique and the corresponding communication software, wireless long way data transmission can be realized. The system of soil parameter automatic monitoring is composed of soil and air environment sensors, GPRS and database. Monitored data is standardized and directly transmitted from sensors to a secure database using the Internet. Key technology of banana Soil parameter automatic monitoring is as shown in Figure 1. Fig. 1 Key technology of banana soil parameter automatic monitoring Key technology of banana growth parameter automatic monitoring. Using sensor and wireless sensor technology with observation, banana plant height, stem diameter, root distribution, leaf area index, petiole length and number of leaves can be measured in the whole process of
