To be sure, in the past ten years of agricultural production, nitrogen fertilizer has played an important role in increasing crop yields, and to some extent alleviated the contradiction between food supply and demand. However, with the increase in the amount of nitrogen fertilizer applied, excessive nitrogen fertilizer has brought about The soil pollution problem has become more and more serious. In fact, reasonable application of nitrogen fertilizer will have a better effect on crop yield and efficiency, and it will be more beneficial to the sustainable development of agriculture. Therefore, starting from the demand for precise management of plant nitrogen fertilizer, the industry has used the chlorophyll meter for professional Explore and research.
What is the relationship between the chlorophyll meter and the precise management of plant nitrogen fertilizer? In fact, the relationship between them is very close. Chlorophyll content is an important indicator of plant health. The profit and loss of plant nitrogen fertilizer can be assessed by measuring plant chlorophyll content. Therefore, using a chlorophyll meter to determine the leaf green content of plant leaves is an important technical means to help users understand crop nitrogen nutrition status , Accurate data can guide users to scientifically and rationally specify nutritional formulas to achieve precise management of plant nitrogen fertilizers. For example, it can be found in the early stage of nitrogen deficiency in plants to avoid missing the fertilization time. Through this scientific method, not only can the waste of nitrogen fertilizer and the adverse effects of excessive nitrogen application be effectively avoided, but also the growth of crops will be healthier and it will be easier to obtain a high-quality harvest.
The chlorophyll meter plays an important role in guiding the precise management of plant nitrogen fertilizers. In recent years, it has been verified in demonstration agricultural production. Through this technical method, it has strongly promoted the progress of China's nitrogen fertilizer application technology, and to a certain extent It alleviates the adverse effects of excessive application of nitrogen fertilizer. At present, the chlorophyll meter is used in many scientific research fields such as chlorophyll meter plant nutrition (nitrogen fertilizer precise management); crop cultivation (judgment of growth stage); crop selection and breeding; It has been widely used, providing important support for the accumulation of agricultural technology, and effectively promoting the improvement of agricultural quality and efficiency.
