With the progress of society, agricultural instruments are constantly changing and changing. In order to better improve the quality of agricultural production, the quality of individual crops, in recent years, some high-tech instruments have become more and more commonly applied to agricultural workers. Such as the soil nutrient fastness tester, the instrument is mainly used to test the available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter content in soil, plants, chemical fertilizers, biological fertilizers and other samples, soil pH and soil Salt content. There are several methods for the use of soil nutrient fastness meters, such as laboratory chemical analysis methods and traditional rapid measurement methods (reagent methods). Now another kind of research and development has been made by using the spectroscopic method to test the near-infrared soil nutrient fastness tester. It is different from the application of traditional soil nutrient speed meter. Let me make some simple analysis below.

First, test the results of the time:
Near Infrared Soil Analyzer: Because it uses spectrometry, it takes only 1 minute.
Traditional soil nutrient tester: Including pretreatment time 40 minutes to 1 hour.

Second, the cost of the later period:
Near-infrared soil nutrient fastness tester: There is no cost other than electricity and no reagents are required.
Traditional soil nutrient speed tester: Reagent cost, between 1.2 yuan and 2 yuan per sample.

Third, scalability:
Near-infrared soil nutrient fastness tester: can change the model or increase the model to test more parameters, extensible.
Traditional soil nutrient tester: can only measure NPK, PH, EC nutrient, no expansion function.

Fourth, function:
Near-infrared soil nutrient speedometer function: It can measure the content of N, P, K, organic matter, water, etc. in soil. If other parameters are needed, it can be input into the model.
Traditional soil nutrient quick-measuring instrument function: Measurable available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter content in soil, plant, chemical fertilizer, biological fertilizer, etc., soil pH, soil salt content the amount.

Fifth, the operation method:
Near-infrared soil nutrient fastness tester: Applying spectral technology, combined with data mining and fusion technology, a rapid test analysis method for soil nutrients was proposed, realizing rapid real-time testing of soil nutrients. Without destroying the sample and without the need for chemical reagents, soil samples can be directly measured by placing soil samples in the sample chamber.
Traditional soil nutrient fastness tester: using the reagent method, the sample needs to be pre-treated, the steps are complicated, and there must be no leakage of the reagent in a step-by-step manner. The staff must be careful when requesting it.

In conclusion, the near-infrared soil nutrient fastness measuring instrument has application spectrum technology, combined with data mining and fusion technology, and proposes a rapid soil and nutrient testing and analysis method, realizing rapid real-time testing of soil nutrients. The test results are fast and the cost is zero. And with scalable performance. Of course, the price of the instrument is also much higher than that of the traditional soil nutrient tester, but according to long-term considerations, it can be regarded as a suitable instrument for various scientific research units and researchers. Because it saves time, saves money, saves energy, and expands performance.

The continuous development of the era of near-infrared soil nutrient fastness testers will generally enter the agricultural research unit and be widely used. We also hope that high-tech, high-efficiency instruments can be used more widely. So that the country's agricultural production of water can be more and more high.
