With the advancement of society, the instrument is also changing day by day. Agricultural instruments are also constantly changing. In recent years, some high-tech instruments have become more and more popular in the hands of agricultural workers. For example, the soil nutrient meter mainly tests the available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter content, soil pH and soil salt content in samples of soil, plants, chemical fertilizers and biological fertilizers. There are several methods for using soil nutrient meters, such as laboratory chemical analysis methods and traditional rapid measurement methods (reagent methods). Now another method has been developed, which uses a spectroscopy test - a near-infrared soil nutrient meter. What is the difference between the application and the traditional soil nutrient speed meter? Let me make some simple analysis below.
First, the function:
Near-infrared soil analyzer function: It can measure the content of N, P, K, organic matter and moisture in the soil. If other parameters are needed, the model can be input.
Traditional soil nutrient rapid tester function: It can measure available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter content, soil pH and soil salt in soil, plant, chemical fertilizer, biological fertilizer and other samples. the amount.
Second, the operation method:
Near-infrared soil analyzer: Using spectral technology, combined with data mining and fusion technology, a rapid test and analysis method for soil nutrients was proposed to realize real-time rapid testing of soil nutrients. The nutrient content in the soil can be measured by not damaging the sample, without chemical reagents, and directly placing the soil sample into the sample chamber.
Traditional soil nutrient rapid tester: using the reagent method, the sample needs to be pre-treated, the steps are cumbersome, and the reagents can be omitted step by step, and the requirements of the staff must be careful.
Third, test the results time:
Near-infrared soil analyzer: Because it uses spectroscopy, it takes only 1 minute.
Traditional soil nutrient rapid tester: including pre-treatment time of 40 minutes - 1 hour.
Fourth, the late cost:
Near-infrared soil analyzer: There is no cost other than electricity, no reagents are required.
Traditional soil nutrient rapid tester: reagent cost, between 1.2 yuan and 2 yuan per sample.
V. Scalability
Near-infrared soil analyzer: You can change the model or add models to test more parameters, and the scalability is super.
Traditional soil nutrient rapid tester: can only measure NPK, PH, EC nutrients, no extended function.
Finally, the near-infrared soil analyzer has: applied spectroscopy technology, combined with data mining and fusion technology, proposed a rapid test and analysis method of soil nutrients, realizing real-time rapid testing of soil nutrients. The test results are fast, and the cost is zero at the end. And has scalable performance. Of course, the price of the instrument is also much higher than that of the traditional soil nutrient speed meter, but it is a kind of satisfactory instrument suitable for all scientific research units and researchers according to long-term consideration. Because it saves time, saves money, saves energy, and has strong performance.
The continuous development of the era of near-infrared soil analyzers will generally enter the agricultural research unit and be widely used. I hope that high-tech, high-efficiency instruments can be used more widely. As a result, the country's technology and water products can be higher and higher.
