In recent years, as a new type of fertilizer, total water-soluble fertilizers (abbreviated as water-soluble fertilizers) have been recognized and accepted by more and more farmers, and are generally applied to greenhouse vegetables. However, in my interview with the countryside, the author found that many households used water-soluble fertilizers that were not right. As a result, they spent money to buy fertilizer, but they did not use the benefits. This device is used to delivery supplemental oxygen to a patient or person in need of extra oxygen.

The total nutrient content of water-soluble fertilizer is more than 50%, and contains a variety of trace elements, compared with the general compound fertilizer, nutrition is comprehensive, fully soluble in water, high absorption and utilization. Combining these characteristics of water-soluble fertilizers, the majority of farmers should have some skills in their application.
First of all, do not rush directly in accordance with the practice of flushing compound fertilizers. Instead, adopt the “double dilution†method. The authors found that some farmers directly applied water-soluble fertilizers in accordance with the practice of flushing common compound fertilizers. As a result, non-uniform fertilization caused damage to the roots and yellow leaves of vegetables with a large amount of fertilizers. The growth is affected. The water-soluble fertilizer has higher nutrient content than the general compound fertilizer, and the amount of water-soluble fertilizer is less than 8 to 10 kilograms. It is recommended that farmers can make a flushing bucket in advance and set a switch at the bottom of the bucket. Before flushing, first dissolve the water soluble fertilizer in the flushing bucket, calculate the amount of fertilizer, turn on the switch, and let the fertilizer solution be flushed along with the watering. In addition, farmers can directly use the electric sprayer as a container for diluting the fertilizer solution for replenishing fertilizer. The purpose of twice-dilution rations is to ensure uniform fertilization and improve fertilizer utilization.
Second, point application of water soluble fertilizer should pay attention to the amount of application. Acupuncture fertilization has the characteristics of concentrated use of fertilizer, high utilization, and less fertilizer. In the author's interview, it was discovered that many households did not accurately determine the amount of water-soluble fertilizer applied to their aquifers, resulting in burning roots and burning seedlings. Therefore, the point of application of water-soluble fertilizer must pay attention to the amount of application, such as Fang Run (20:20:20) water-soluble fertilizer, to acupuncture facilities 3 ~ 5 grams is appropriate, but also with the soil after mixing and planting seedlings.
Finally, when water-soluble fertilizers are sprayed, they should be used as a single product or mixed with non-alkaline pesticides. When there is a deficiency in vegetable crops or poor root growth, many farmers choose to use water-soluble fertilizers to spray them. The authors suggest that farmers should spray water-soluble fertilizers as far as possible, or be mixed with non-alkaline pesticides to prevent metal ions from reacting to produce precipitation, resulting in leaf fertilizer or injury.
