Agrochemical service system is an important link for scientific fertilization. Its characteristics are:
(1) The production, sales and application of chemical fertilizers should be closely integrated, that is, industry, commerce and agriculture should be integrated through agrochemical services. This has broken the previous situation that the production, sales and application of chemical fertilizers were not connected with each other, and strengthened the relationship between industry and agriculture.
(2) Fertilizer products are closely combined with fertilization technology. Through agrochemical services, we can provide farmers with appropriate chemical fertilizer varieties and corresponding fertilization technologies according to the needs of agricultural production in a certain area, guide farmers to apply fertilizer, improve the use efficiency of chemical fertilizer, and increase farmers' income. As the agrochemical service reduces unnecessary circulation links, farmers can easily purchase the fertilizer they need and obtain fertilizer information at the same time. The production and marketing system can also timely obtain farmers' requirements for fertilizer application effect and new fertilizer development, so as to better meet the needs of agricultural production.
(3) Through agrochemical services, we can evaluate the application effect of various fertilizer products, predict the demand for fertilizer, provide decision-making basis for the production and supply of fertilizer, facilitate the formulation, implementation and demonstration of fertilizer policy, and promote new fertilizer technology.
Abroad, the agrochemical service system has a wide range of contents, including soil nutrition diagnosis, plant nutrition diagnosis, recommended fertilization and alternative fertilization, which combines the production, sales and fertilization of chemical fertilizers and is conducive to the scientific implementation of fertilization tasks.
In order to diagnose soil and plant nutrition, commercial laboratories can complete a lot of testing tasks for farmers or farms, and determine the agrochemical formula of target yield based on crop nutrition needs, soil fertilizer supply characteristics, and fertilizer types and characteristics. Later, according to the requirements of farmers or agricultural production units, fertilizer sellers or fertilizer distribution stations targeted to carry out a series of agrochemical services such as secondary processing of fertilizers and completing fertilization on behalf of others, which greatly improved the yield and economic benefits of fertilizers, thus further improving and developing the various businesses of agrochemical services. This has promoted the combination of fertilizer production, sales and use, and promoted the development of compound fertilizers in the direction of multiple varieties and specifications.
In recent years, after the emergence of high concentration simple chemical fertilizers, low, medium and high concentration compound fertilizers and special fertilizers in China, due to the lack of agricultural chemical services, economic losses caused by improper use of fertilizers have occurred from time to time. It is necessary to learn from foreign experience, establish an agrochemical service system that combines production, marketing and use, and send fertilizer and fertilization technology to farmers at the same time.
The agrochemical service organization of the fertilizer plant shall adhere to the principle of "everything has been tested" to promote the sale of chemical fertilizers and provide services before, during and after the sale. At present, factories, agricultural means of production and agricultural departments all have experience in carrying out soil testing and fertilization, processing various special fertilizers, and establishing fertilizer distribution stations. According to the specific situation, each region can establish an agrochemical center and network at the county level, which can not only supply fertilizer, but also guide farmers to apply fertilizer scientifically.
