Introduction of common soil testing instruments (1)
1. Soil (fertilizer) nutrient speed measuring instrument
Also known as soil nutrient speed measuring instrument, fertilizer nutrient speed measuring instrument, plant nutrient speed measuring instrument, mainly used for soil, fertilizer, water, salt, ph value, total nitrogen, ammonium nitrogen, alkali nitrogen, effective phosphorus, Effective potassium, calcium, magnesium, boron and other trace element content test. Accurate understanding of soil nutrient content can guide farmers to properly measure soil fertilization. Accurate fertilization can not only improve crop yield and quality, but also effectively avoid environmental problems caused by excessive fertilization.
Second, the soil moisture tester
Soil moisture (moisture) and temperature are important components of the soil and play an important role in crop growth and water-saving irrigation. Mastering the soil moisture (water) and temperature distribution provides a scientific basis for differentiated water-saving irrigation, while precise water supply is also conducive to increasing crop yield and quality.
Third, multi-point soil moisture speed measuring instrument
The whole process keeps track of the data in the environment under test, and the recording time is long. It has the function of automatic storage protection of power-off data. The machine is small in size and adopts the design concept of hand-held style. The software is easy to operate and reliable. The whole machine consumes a small amount of power and is powered by a built-in battery. The battery can be powered for more than half a year.
The software is powerful, the data is easy to view, and the data in the recorder can be exported to the computer at any time, and can be stored as an EXCEL form file to generate a data curve for further analysis by other analysis software. The recorder can work independently from the computer. When the current environment data needs to be viewed, the data in the recorder can be read by the computer through the USB communication interface. The large-screen Chinese liquid crystal display can display the water value, the number of groups, and the low-voltage alarm in real time, which is convenient for field work. A variety of soil formulations can be set to facilitate a variety of soil testing.
Fourth, soil moisture fixed point collection instrument
It can be used to measure the water content of different depth profiles of the measured object such as soil. The FDR principle is based on the difference in the reflection of electromagnetic waves emitted by the detector in different dielectric constant substances. Calculate the water content of the measured object.
Five, soil moisture automatic measurement system (wireless type)
The wireless intelligent soil moisture automatic measuring system can simultaneously measure the soil volume and water content of the soil surface layer and different depths, and has high measurement precision, large storage capacity and small volume. It can be used for long-term monitoring of farmland, water conservancy, forest, lawn, road, railway maintenance, etc. It can continuously monitor soil moisture, with stable performance, high reliability and maintenance-free.
The automatic soil moisture measurement system can automatically collect and wirelessly transmit soil moisture data under unattended conditions in fixed stations. The data is automatically received and stored in the monitoring center; 24 hours of continuous online monitoring can be realized and the monitoring data can be transmitted in real time. The transmission method transmits the soil moisture monitoring data to the monitoring center in real time, generates reports and statistical analysis. The staff can timely and accurately grasp the soil condition of the monitoring station, so as to reflect the soil changes in the monitored area more comprehensively, scientifically and truly, and provide effective soil moisture information for disaster reduction and drought resistance.
The soil moisture automatic measurement system software is powerful, can view data in real time, and the data update rate is fast. It can be automatically stored according to the set collection interval. The data can be exported to EXCE form file to generate data curve for further analysis and processing by other software. The printer is connected to print the stored data.
The data is collected in real time, and the wireless communication controller can realize the real-time monitoring of the moisture of each station by the monitoring center. The system adopts the communication technology of network modules such as GPRS and 3G, which is not limited by distance and the data transmission is stable and reliable.
