Application research of soil (fertilizer) nutrient speed measuring instrument
In the research and promotion of soil nutrient rapid measurement technology, we found that the soil (fertilizer) nutrient speed measuring instrument and its supporting rapid measuring method should be widely promoted at the grassroots level, and should have the following functions.
(1) The instrument should be used for both AC and DC. Only instruments with both AC and DC can be used in the field without electricity or in the villages or fields.
(2) The work of the instrument should be stable and reproducible. The soil (fertilizer) nutrient speed meter only has this function, and it has the value that can be used.
(3) The test method required to be matched with the instrument is simple, easy to operate, easy to master, and the test speed is fast. Only when the instrument has this function can it be promoted and used at the village level, so that the rural agricultural technicians with low cultural level can master the use of the instrument well. In the research, it was found that it is difficult for the grassroots technician to master the same method as the conventional one, such as the pretreatment and testing process of the soil sample, and even the reagents used in the test are the same as the conventional analysis method.
(4) The package must be complete. In research and promotion, it is found that in terms of current economic strength and technical strength, laboratories have not yet been established in rural and rural areas in China. Grassroots technicians have not been engaged in soil testing and fertilization techniques. For them, soil determination Nutrient, guiding farmers to balance fertilization is a brand-new technical work. They hope that they can work very conveniently without relying on the laboratory. This requires that the soil and fat analyzer should be complete, and instruments, reagents, and utensils must be taken. When used, the instrument can function as a small laboratory.
(5) The soil (fertilizer) nutrient speedometer solves the above four problems, and only solves the problem that the soil (fertilizer) nutrient speedometer meets the problem of measuring soil in a large area at the grassroots level, and there is still a key technology to be solved - how to use The speed measurement results to guide balanced fertilization. This problem is a problem that some experts and soil and fertilizer measuring instrument production units are trying to explore and solve in recent years. After some experts have discovered that if the instrument has the above four functions, the speed measurement is solved. After the results of the abundance index or the quick-test formula, the soil and fat analyzer can be used to guide balanced fertilization, and it can also be widely promoted.
