The use of soil nutrient analyzer and its significance
The soil nutrient analyzer 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 the leaf The nitrogen content is closely related, so the chlorophyll measurement can also indicate the true nitro requirement of the plant. This portable chlorophyll meter can guide the rational application of nitrogen fertilizer, increase the nitrogen utilization, and protect the environment (prevent the application Too much 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 soil nutrient analyzer is an instrument that displays the greenness of plants 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.
Because soil nutrient measuring instrument has fast measuring time, LCD directly displays chlorophyll value, the instrument is small and portable, can carry the function characteristics of field measurement, and it is favored by more and more professionals through various plant leaf measurement samples.
