Agricultural resources dealers to purchase soil nutrient speed tester

From the beginning of the reform of the chemical fertilizer circulation system in 1998 to the complete liberalization of the fertilizer market in 2009, a batch of batches of agricultural resources dealers entered the agricultural capital industry, and the agricultural resources dealer groups have also experienced rapid growth while experiencing market competition. Nowadays, the agri-food industry has shown an overall overcapacity situation. How to get out of a characteristic business path in the oversupply and intensely competitive agri-food industry has been a dilemma for agricultural materials dealers to solve urgently.

Agricultural resources belong to special commodities. It should be said that professional agricultural knowledge should be qualified to operate agricultural resources. In recent years, especially in the areas of vegetables and fruit trees, professional agricultural technicians have become one of the important factors for improving the market competitiveness of agricultural investment stores. An agricultural expert once said: "The competition in the future agricultural industry will depend on technological competition. Farmers are willing to look for people who understand agricultural technology to buy things. If you pass your technical guidance, you can remedy the disease and solve the problem for farmers. Practical problems, the peasants will certainly believe you." Therefore, agricultural resource dealers can use technology as a service highlight, provide farmers with crop production technology and crop sales information, and will certainly be welcomed by farmers.

Farmers are generally concerned about the production of crops and the selling price of crops. The factors affecting crop yield are seed, fertilizer, and pests. Among them, fertilizer plays a very important role in crop production and is the largest material investment in farmers' productive investment. However, due to some unreasonable factors in the use process, the production performance of the fertilizer has not been effectively exerted, the utilization rate of the fertilizer is reduced, the waste of fertilizer resources is serious, the agricultural production cost is increased, and the benefit is reduced.

In view of the above situation, the agricultural resources dealers may consider providing scientific methods for soil testing and fertilizing for farmers, increasing the utilization rate of fertilizers and reducing the production costs of farmers. Corresponding agricultural distribution stores will be welcomed by farmers.

The method of soil testing and fertilizer application is a set of technical integration, including five parts: (1) collection and treatment of soil samples; (2) analysis of laboratory tests; (3) adsorption test of soil for nutrients; (4) Greenhouse or net room pot experiments; (5) Field trials. This method fully considers the status and balance of large, medium, and trace elements in the soil; the use of a joint extractant increases the efficiency of the work; through indoor analysis and pot experiments we can basically understand the nutrient status of the soil and the application of fertilizer to the soil. Some of the reactions that followed allowed us to avoid blindness when designing experiments, save manpower, material resources, and achieve maximum yield goals in field research, and formulate a rational balance fertilization plan to achieve a balanced fertilization in the true sense. However, this method has many links and is more complicated; the basic equipment for soil fertility analysis and adsorption test requires higher equipment and means, and the equipment required for potted earthworm testing is also more special. This method is more difficult for agricultural materials dealers. .

The soil nutrient speed measuring instrument is a portable instrument developed and produced according to the rapid measurement method and has a series of advantages: the "chassis/medicine-integrated aluminum alloy chassis" is designed to be portable, durable, supporting detection methods and finished product medicaments. . Microcomputer control, digital circuit, program design, liquid crystal display, AC and DC, can be field flow testing, to minimize the operator's mistakes and labor intensity. Widely used in contracted land, agricultural resources dealers, soil fertilizer stations, and some agricultural colleges and universities.
