Operating course of chlorophyll meter

The plant nutrient analyzer can measure the relative chlorophyll content (SPAD) or green degree, nitrogen content, leaf surface humidity and leaf surface temperature of plants in real time, so as to understand the real demand of nitro group in plants and the lack of nitro group in soil or whether nitrogenous fertilizer is applied too much. This instrument can increase the utilization rate of nitrogen fertilizer and protect the environment. It can be widely used in the research of plant physiological indexes and the guidance of agricultural production in agricultural and forestry related scientific research institutions and universities.
