The traditional concept of fertilization has allowed us to believe that only when there is more fertilization, crops will produce more, but in fact, from the perspective of scientific agriculture, this concept is wrong and it is also outdated. Only precise fertilization is possible. Really realize high production and high quality, and do not cause pollution to the soil environment and ensure the sustainable development of agriculture. Therefore, modern agriculture pays more and more attention to precision fertilization, and to achieve accurate fertilization, it is necessary to make use of specialized instruments such as chlorophyll content meters to understand the laws of fertilizer requirements for crops, and use them as the basis for achieving the best nutrients. management.

Chlorophyll content meter

Generally speaking, in agricultural production, the three most widely used fertilizers are NPK and the chlorophyll content meter is mainly used for N nutrition management of crops. Taking potato cultivation as an example, nitrogen fertilization is always a double-edged sword in the course of fertilization. If nitrogen is applied properly, it will not only increase potato yield but also improve quality. On the contrary, it will cause many environmental problems. Will threaten production. Therefore, how to implement a reasonable application of nitrogen fertilizers determines the quality of potato cultivation. At this time, the use of chlorophyll content meter to determine the chlorophyll content of potatoes can clarify the actual nitrogen application status of potato crops, thus providing important for reasonable fertilization and precise fertilization. Scientific basis.

Studies have shown that from the seedling stage to the harvest time, the potato has a single-peak curve of nitrogen uptake. During the seedling and tuber formation stages, potato uptake of nitrogen accounts for 9% and 19% of total nitrogen uptake during the whole growing period. Tuber enlargement accounted for 52% and then declined. Therefore, in the process of potato growth, we should effectively manage nitrogen based on the potato's absorption pattern of nitrogen and the true nitrogen nutrition status of the potato crop as determined by the chlorophyll content meter, and determine the precise fertilization time and fertilization amount. Achieve optimal nutrient management, so that it can ultimately achieve efficient potato cultivation, greatly improving the economic benefits of potato cultivation.
