Water-soluble fertilizer has obvious advantages in improving fertilizer utilization rate, saving agricultural water, reducing ecological environment pollution, improving crop quality and reducing labor. Pay attention to the following technical points when applying water soluble fertilizer: 1. Avoid direct application. The water-soluble fertilizer that needs to be diluted twice has higher nutrient content than the common compound fertilizer, and the dosage is relatively small. The direct application of the fertilizer is easy to cause the phenomenon of burning roots, small seedlings, and weak seedlings. The second dilution is not only conducive to uniform application of fertilizer, but also Improve fertilizer utilization. 2. A small amount of multiple administrations. Because of the quick-acting effect of water-soluble fertilizer, it is difficult to remain in the soil for a long time. A small number of times is the most important principle of fertilization, which is consistent with the characteristics of continuous absorption of nutrients by plant roots, reducing the leaching loss caused by one-time large-scale fertilization. Generally, the amount per acre is 3 to 6 kg. 3. Pay attention to nutrient balance. The water-soluble fertilizer is generally applied by pouring or spraying, or mixed into water, and applied with irrigation (drip irrigation, sprinkler irrigation). It should be reminded that when using drip irrigation, due to the dense growth and large amount of crop roots, the dependence on soil nutrient supply is reduced, and more depends on the nutrients provided by drip irrigation. If the water soluble fertilizer formula is not balanced, it will affect crop growth. In addition, water-soluble fertilizer should not be applied with traditional irrigation methods such as flood irrigation or irrigation, to avoid fertilizer waste and uneven application. 4. Cooperate with application. Water-soluble fertilizer is a quick-acting fertilizer, which can only be used as a top dressing. Especially in conventional agricultural production, water-soluble fertilizer is not a substitute for other conventional fertilizers. It is necessary to combine the basic fertilizer with the topdressing fertilizer, the combination of organic fertilizer and inorganic fertilizer, and the combination of water-soluble fertilizer and conventional fertilizer in order to reduce the cost and exert the advantages of various fertilizers. 5, try to use alone or mixed with non-alkaline pesticides. When vegetables are deficient in deficiency or root growth is poor, many farmers use water-soluble fertilizers to alleviate them. It is reminded that the water-soluble fertilizer should be applied as much as possible or mixed with non-alkaline pesticides, so as to prevent the metal ions from reacting to produce precipitation, causing fat or phytotoxicity. 6. Avoid excessive irrigation. When the main purpose of fertilization is to irrigate, the depth of the root layer can be wetted. Different crop root depths vary widely, and the soil can be excavated at any time to understand the specific depth of the root layer. Excessive irrigation not only wastes water, but also causes nutrients to leap below the root layer, crops cannot be absorbed, and fertilizer is wasted. In particular, urea and nitrate nitrogen fertilizers in water-soluble fertilizers (such as potassium nitrate, calcium ammonium nitrate, nitrophosphate, and water-soluble fertilizers containing nitrate nitrogen) are easily lost with water. 7. Prevent the accumulation of salt on the surface. Long-term use of drip fertigation in greenhouses or greenhouses will cause accumulation of surface salt and affect root growth. Under-film drip irrigation can be used to inhibit salt migration to the surface layer. Disclaimer: Some articles on this website are transferred from the Internet.
