The chlorophyll detector can measure the relative chlorophyll content or “greenness degree†of the plant instantly. The chlorophyll content in the plant leaf indicates the condition of the plant itself. The leaves of the plant with good growth will contain more chlorophyll, the content of chlorophyll and nitrogen in the leaf. The content is closely related, so the chlorophyll measurement can also indicate the actual nitro requirement of the plant. This portable chlorophyll meter can guide the rational application of nitrogen fertilizer, improve nitrogen utilization, and protect the environment (prevent the application of More nitrogen fertilizer pollutes the environment, especially the water source.
Experts suggest that nitrogen has a significant impact on crop growth, yield and quality. In the absence of nitrogen, the production of crop roots was significantly inhibited, and the formation and development of reproductive organs was also limited. The plants matured in advance and the fruits were small and unfilled. However, too much nitrogen fertilizer application will reduce the nitrogen use efficiency. Most of the excess nitrogen fertilizer will enter groundwater and surface water, causing continuous accumulation of nitrate nitrogen in groundwater and surface water, resulting in eutrophication of the water, leading to a series of environmental problems. Therefore, how to apply nitrogen fertilizer in an appropriate amount to minimize the use of nitrogen fertilizer to reduce costs and environmental pollution without causing a reduction in production is an important content of the research on precision agriculture.
The chlorophyll detector is an instrument that displays the greenness of a plant by measuring the padding value. It measures the SPAD value, guides the application of nitrogen fertilizer and understands the growth of the plant. Chlorophyll meter can immediately measure the relative content of chlorophyll in plant leaves and display the measurement figures on the LCD display of the instrument.
Due to the fast measurement time of chlorophyll detector, LCD directly displays chlorophyll value, the instrument is small and portable, and can carry the function of field measurement. Through various plant leaf measurement samples, it is favored by more and more professionals and more chlorophyll.

Galvanized steel coil is a material produced by continuous hot-dip galvanizing process with hot-rolled steel strip or cold-rolled steel strip as the substrate. Hot dip galvanized coil supplied in coil form after coiling. Therefore, galvanized steel sheet (coil) can be divided into hot-rolled galvanized sheet coil and cold-rolled hot-dip galvanized sheet coil. They are mainly used in the fields of construction, household appliances, automobiles, containers, transportation and household industry. Especially in steel structure construction, automobile manufacturing, steel warehouse manufacturing and other industries. Their main characteristics are: strong corrosion resistance, good surface quality, benefit from deep processing, economy and practicality, etc.
Galvanization is the leading method to protect metals from environmental elements that cause corrosion, rust, and the eventual weakening of the steel. Hot-dip galvanizing deposits a thick, robust layer of zinc iron alloys on the surface of a steel item.When exposed to the atmosphere, pure zinc reacts with oxygen to form zinc oxide which further reacts with carbon dioxide to form zinc carbonate. A dull, grey, fairly strong material that stops further corrosion in most circumstances, protecting the steel from the elements. Galvanized steel is widely used in applications where rust resistance is needed. Galvanized steel is commonly used in the automotive industry to enhance the corrosion performance of exterior body parts. Galvanized Steel is magnetic.
