        Portable chlorophyll meter short chlorophyll meter, also called portable chlorophyll meter, and handheld chlorophyll meter, handheld chlorophyll meter, SPAD chlorophyll meter as an effective tool relative chlorophyll content of the plants is measured. There are several different types of chlorophyll: chlorophyll a and b are the main types of chlorophyll a and b plays a vital role in plant growth, the precise determination of its content, for the growth conditions of crops, plant pathology diagnosis provided scientific basis for the implementation of precision agriculture is the key.

        TYS-A portable chlorophyll meter, also known as portable chlorophyll meter, a portable chlorophyll meter blades by measuring the light transmittance in two wavelength ranges to determine the relative amount of chlorophyll in the leaves of the current, which is in chlorophyll selective absorption of a specific wavelength of light.

 

         Two wavelength regions, depending on the amount of transmitted light to calculate the blade measurements. With respect to, TYS-A, TYS-B in terms of portable chlorophyll meter, SPAD chlorophyll meter series in ensuring the premise does not reduce crop yields, can help reduce 10 percent of nitrogen fertilizer.

Also known as handheld handheld SPAD chlorophyll meter, TYS-A handheld chlorophyll meter, you can instantly measure the relative content of chlorophyll of plants. Chlorophyll content indicates the status of the plant itself, but also to explain chlorophyll measurements Nitro plant's demand. This model chlorophyll handheld meter can store data on a host and see. Measurement time fast, LCD direct display of chlorophyll, the instrument portable, can carry to the field measurements of chlorophyll meter is a handheld, the main function of chlorophyll meter handheld features.

 

         Currently, the market can detect chlorophyll As tools are hand chlorophyll meter, handheld chlorophyll meter, SPAD chlorophyll meter, chlorophyll meter, a portable chlorophyll meter, a portable chlorophyll meter. Top instruments introduced in response to market demand TYS-A, TYS-B, SPAD-502 chlorophyll meter three series.

Instrument name: Portable chlorophyll meter / chlorophyll meter / Portable chlorophyll meter

Instrument Type: SPAD-502

Nitrogen (N) element control management

Nitrogen (N) element played a very important role in the growth process of crops.

For growers, crop nitrogen demand to know, you can control the supply of nitrogen in the appropriate quantity.

Some experiments show that, SPAD series in ensuring the premise does not reduce crop yields, can help reduce 10 percent of nitrogen fertilizer.

In the amount of nitrogen fertilizer will be controlled to the optimum, it can reduce crop diseases and environmental pollution due to excessive use of nitrogen fertilizer that may arise.

We have more and more people are beginning to realize that excessive use of nitrogen pollution caused by the lake water and groundwater and begin to realize the importance of the proper use of nitrogen fertilizer.

Nitrogen applied technology in the development of present and future, SPAD series products are playing an increasingly important role.
