The previous fertilization management work actually ignored the nutritional testing of plants to a certain extent, and only carried out based on manual experience. Therefore, the effect of fertilization was not scientific and reasonable enough, which affected the absorption and utilization of nutrients by crops, and caused a waste of resources. , Which also limits the benefits of agricultural production to a certain extent. With the rise of scientific agriculture, there is an increasing demand for plant nutrition testing in agricultural scientific research and production guidance. In order to be able to judge plant nutrition scientifically and accurately, the industry mainly uses plant nutrition tachometers for determination. In the process of plant growth and development, a variety of nutrient elements are needed, and nitrogen is particularly important. Among all necessary nutrient elements, nitrogen is the primary factor that restricts plant growth and yields. It also has a significant effect on improving crop quality. In the case of insufficient plant nitrogen nutrition, we need to apply nitrogen fertilizer to supplement it, but if plant nitrogen nutrition is sufficient, and if nitrogen fertilizer is continued to be applied to the land, it will cause waste of resources and nitrogen fertilizer pollution, but it will not pay for it. Therefore, in order to better grasp plant nutrition and explore scientific, effective and reasonable nitrogen fertilizer fine management methods, the industry has carried out a number of studies and a number of feasibility applications in agricultural guidance using plant nutrition tachometers, and achieved some good results. Effectiveness. The nitrogen nutrition of plants can be analyzed by detecting the chlorophyll and nitrogen content of plant leaves. Plant nutrition tachometer is a professional instrument used to determine these nutritional parameters of plants. It can help to quickly obtain these plant nutrition data and provide important technical support for scientific understanding of plant nutrition status. On the one hand, it uses plant nutrition tachometer to Scientific judgment of plant nutrition can develop the physiological and molecular mechanisms of plant nutrient absorption and utilization, plant nutrient genetics and improvement, plant-soil-microbe interaction rhizosphere process and regulation, fertilizer creation and fertilization technology, nutrient cycling and nutrient resource management, Agronomy research and research related to nutrient reuse and pollution control, to master and accumulate more abundant and effective scientific research materials. On the other hand, the rapid detection function of the plant nutrition rapid tester can also help modern farmers to quickly grasp the plant nutrition status, and then guide scientific fertilization and improve the efficiency of nitrogen fertilizer use.
