Pei Xinchong it is pointed out that the agricultural informatization service level of countries such as America, law, germany, and the like is high, the service content is rich, the data information transmission is fast, and agricultural information inquiry platforms are many. Bolarin and ayan lade illustrate the basic features of agricultural information, guiding the pricing methods and policies of agricultural information. Bonnen believes that governments have made great financial support for the development and promotion of agricultural information [14]. The Cash discovers the agricultural information, so that the agricultural productivity of recipients is obviously improved. Basian et al state that modern information technology devices have a significant impact on the efficient transfer and utilization of agricultural information. Streeteter finds that rural information network infrastructure is behind in one investigation aiming at agricultural technology popularization personnel, and development is not matched and unbalanced seriously restricts the development of modern agriculture. Riesenberg et al state that agricultural information promotion management, planning and implementation of a promotion education system, professional ability of promotion personnel, promotion organization internal relation, organization flow and portable information agricultural information receiving terminals have important influence on the propagation and application of agricultural information.
ADhinrra et al believe that rural information demand and service research still tends to introduce advanced information and propagation techniques, and rural agricultural information demand and service problems are solved by exploring the information demand of the rural poor. Research on information requirements of farmers in the middle and western united states by Mark Tucker et al indicates that farmers can know related information in various ways such as telephone consultation, online inquiry, face-to-face hearing and the like in order to reduce pollution of harmful chemical fertilizers and pesticides, so that better prevention can be made in practice. The Dhayal and Bochalya artificial, agricultural expert system is widely used for production management, pest control, fertilization and irrigation of crops. Shaukat and Shah are artificial "precision agriculture" and have been widely used in the whole process of production, management and management of wheat, corn and soybean, including cultivation, irrigation, fertilization, pest control, harvesting, and transportation and sales.

Ruan Huaijun, etc., indicates that agricultural informatization is an important embodiment of the level of agricultural modernization, and is also an important measure for overcoming low agricultural yield and poor economic benefit and realizing the key development of 'three agriculture'. Gao Molin and the like consider that the agriculture informatization is fully based on a modern information technology platform and system, provides omnibearing information support for related management and service before, during and after the agricultural production, and promotes the comprehensive economic benefit of agriculture. Fu Hongxun modern information technology is believed to play a significant role in the agricultural development system. Deng Zongbing and Luo Qianwen are believed to be increasingly prominent in the various stages of agricultural production management as information technology is rapidly evolving. Domestic scholars have also conducted a great deal of research on the integration and application of smart phones in agriculture, and the research emphasis includes the development of the application of agricultural expert systems based on Android systems, rural electronic commerce and the like.
With the advent of the smart age, smart phones are increasingly being used in agriculture. Zhang Xi agricultural information service platform design based on smart phone indicates that the agricultural information service system of smart phone service management mode will play a positive promotion role in the agricultural informatization field of China. Jiang Yifeng shallow smart phones indicate that agricultural production and management will become intelligent, automated and digitized in the application of smart agriculture. Leave and the like consider that WAP wireless application protocol technology can effectively solve the problem of 'last kilometer' of rural informatization, and the application of smart phones is popular, so that the process of agricultural informatization degree is greatly accelerated. Yang Linnan and the like are based on Android mobile phone clients, are based on user requirements and agricultural disease, pest and disease basic diagnosis systems, and are effectively applied to comprehensive control of sweet corn diseases and pests. Chen Guipeng and the like rely on smart phones as information, and a comprehensive, systematic and comprehensive service platform for agricultural information is constructed by utilizing the characteristics of wide coverage, portability, multifunction, quick network speed, large memory and low cost, so that informatization service [31] from farmland and fertilization to consumption in agricultural production is realized. And enemy days and months and the like, an information acquisition and release system of the agricultural Internet of things is designed, so that the collection, screening and release of related contents are realized, and a brand-new technical path is opened for obtaining environment monitoring data by tightly combining agricultural production and scientific research.
APP is continuously combined with agriculture, so that farmers are very rich in agricultural information acquisition modes and agricultural production modes. Wang Danfeng in the discussion of modern agricultural development assisted by mobile phone APP, it is pointed out that mobile phone APP can change people's knowledge of agriculture, is favorable for accelerating transformation and upgrading of agricultural industry, and is favorable for establishing a sound agricultural service system.
Li Mengya in the "use and satisfy" analysis of WeChat applet, it was pointed out that by 2018, the number of WeChat applet on-line was increased from 200 to 58 ten thousand, with a cumulative number of users approaching 4 hundred million, reaching 50% of the number of WeChat users. The WeChat applet is an application that can be opened for use by a user's "swipe" or search without downloading or installation. The mobile phone has the advantages that the problems that the application does not need to be installed, the tentacle is available, the user can run after using up and uninstall the mobile phone, the user does not need to worry about that a large amount of storage space is occupied by installing a plurality of applications on the mobile phone, and the applications are ubiquitous and available at any time are realized.

Key codes used for transferring the parameters when clicking are shown as follows;
wx.navigateTo({
url:'../zw/zwlclassid＝'+data.zwid+'&name＝'+data.name
})
the two parameters are transmitted in a GET mode, the crop information page can directly receive the parameters in a page loading control function onload in a js file of the crop information page, and the code for modifying the title of the page is shown as follows;
the agricultural policy pushing information detail page implementation logic is basically similar to the crop production management information detail page implementation logic, and the method is that the agricultural policy pushing id and name are transmitted by the last page, then data is requested to the background, and the page is rendered after the data is returned to the background;
the consultation and service page is divided into three parts of supply and demand online sites, and the three types of consultation and service in the consultation and service table are respectively corresponding, after clicking a consultation and service button at the bottom of the page, a user loads the three pages at the same time, firstly requests related data of the supply and demand service type to the background, and then requests the data of the online service and the on-site service to the background; because the data size is large, in order to optimize the actual experience of a user, the data of the part adopts a paging reading mode, firstly, an integer type variable is set and the initial value is zero, when the page is pulled down to the lowest end each time, the variable is triggered to self-increment, the variable is transmitted to the background, the background reads the data of the corresponding position in the database after receiving the variable, ten pieces of data are returned at one time, the user is prevented from frequently refreshing the data, and the pressure of a server is reduced; after receiving the data returned by the background, the applet terminal adds the data into a corresponding set, and the codes for realizing pull-down refreshing are as follows;
/>
The logic flow diagram of the logical operation of the advisory and services page is shown in FIG. 18, and the time that occurs when the pull-down bottoming time occurs is the same as the square box portion of FIG. 18;
when a user clicks a new button at the lower right corner in the consultation and service page, the user jumps to the consultation and service release page, the page does not request data from the background when being loaded, and when the user fills in information, the logic control layer actively records the data on the variable; when a user clicks the release button, the system firstly confirms the format of the mobile phone number in a regular expression mode, then determines whether other necessary information is filled in, finally the system can send all data to the back end, and when receiving a return from the back end, the system exits from the release page; the logic diagram of the consultation and service release page is shown in FIG. 20;
the system performs double verification when judging whether the mobile phone number is legal or not; firstly, the verification adopted by the applet end prevents misoperation of a user; secondly, verifying the server side to prevent the illegal operation of a malicious user; the applet side authentication code is as follows:
the verification code of the server is as follows
/>
The system finds a plurality of problems in the actual experience process after the design is finished, firstly, the prompt of the user is insufficient, and the experience given to the user in the process of data loading is system blocking; in order to avoid the current situation, the system refers to the Toast with the WeChat and prompts the user, so that the flow of loading data is not abrupt, and the code used by the prompt box is as follows:
The screenshot of the operation example of the prompt box is shown in fig. 21;
