（1） Process flow: The mobile formula BB fertilizer dispenser is also known as the mobile intelligent fertilizer dispenser. The mobile intelligent fertilizer dispenser is based on the requirements of the national "soil testing formula fertilization project" to provide evidence for fertilizer selection and fertilization. Tailor the formula fertilizer for farmers, so that the field of soil testing and fertilizer matching can be seamlessly integrated with the fertilizer matching expert system to achieve a one-to-one scientific fertilizer matching mode.
（2） Functions and characteristics: The mobile intelligent BB fertilizer dispenser is an effective form of "combining technology with material" for soil testing and fertilization. It directly builds a fertilizer supermarket on the field, which not only solves the "last mile" problem of soil and fertilizer technology promotion and application, but also truly realizes the seamless connection between farmers and enterprises, which can be seen and touched by farmers
It is a new agricultural technology and new achievements loved by agricultural enterprises.
The mobile intelligent BB fertilizer dispenser organically combines soil detection, formulation, fertilizer production, business services and farmer fertilization to form a production, supply, marketing and application - integrated service system. It integrates and packages soil detection formulation technology, formulated fertilizer products and social services, realizing industrialization of technical achievements, specialization of technical services, and intellectualization of formulated fertilizer production The "four modernizations", such as personalized application of formula fertilizer, are synchronized to fundamentally change farmers' fertilization habits. Fertilization is carried out according to soil types, crop needs and farmers' needs, so as to improve the output of agricultural products, improve the quality of agricultural products, save costs and increase efficiency, and reduce or prevent pollution caused by improper fertilization.
