Abstract:

Traditional soil nutrient detection methods have problems such as high laboratory requirements, cumbersome procedures, high costs, and long cycles, resulting in poor timeliness and limited application. In order to solve the problem, the soil nutrient rapid detection methods widely used at home and abroad were sorted out. The ASI batch soil nutrient efficient rapid detection technology, the effective nitrogen, phosphorus and potassium combined extraction and analysis method of the Ministry of Agriculture Industry Standard in 2010, and the spectral soil nutrient rapid detection technology and the soil nutrient rapid detection box technology developed by South China Agricultural University were systematically compared with the traditional analysis methods. The results showed: The ASI method was suitable to batch soil nutrient rapid analysis for large quantity samples, but required expensive instruments, equipment and laboratory; the combined extraction and analysis method needed complex reagents with decreased cost, the soil nutrient rapid detection box technology were portable and simple, and could be applied to field diagnosis, these two soil nutrient rapid analysis methods still needed the help of electrophotometer or spectrophtometer. Spectrum rapid technology can obtain results quickly without destroy to soil, which is adaptable to large area of land. However, the instrument is expensive, and the accuracy of the model is significantly affected by soil type and moisture content. At present, there are still challenges in accuracy and application scope of the rapid detection technology. In the future, soil nutrient rapid detection technology will develop in the direction of miniaturization, intelligence, high-throughput and multi-parameter synchronous measurement, and expand application scenarios in combination with UAV remote sensing and other technologies. In order to improve its application value, it is urgent to establish a perfect data quality control system for rapid detection methods, construct a regional correction model based on big data and artificial intelligence, and strengthen the promotion and service of grassroots technology.
