The application of water-soluble fertilizer with integrated water and fertilizer technology has brought a lot of convenience to agricultural production, but bad use will also bring disaster, so it is necessary to strictly control the time and amount of fertilizer. How to use water-soluble fertilizer scientifically? The following is to introduce a water-soluble fertilizer science and technology.
How to apply water soluble fertilizer scientifically
When fertilizing, the temperature of water should be close to the ground temperature and air temperature as far as possible, and do not flood. In winter, the greenhouse should be watered in the morning; in summer, the greenhouse should be watered in the afternoon or evening. If you don’t use a dropper, water it as little as possible.
Flood irrigation is easy to cause soil hardening, root respiration blocked, affecting nutrient absorption, and easy to rot roots, dead trees. Popularizing “ridge cultivation” is beneficial to high yield of crops.
Only scientific fertilization can obtain ideal yield and quality of water-soluble fertilizer. Scientific fertilization not only lies in nutrient formula, quality, but also in scientific dosage.
Generally speaking, land vegetables use 50% of water-soluble fertilizer, the amount is about 5 kg per mu, and the amount of water-soluble organic matter, humic acid, amino acid, chitin, etc. is about 0.5 kg. In addition to increasing nitrogen, phosphorus and potassium nutrients, it can also improve crop disease resistance, drought resistance and cold resistance, and reduce the occurrence of nutrient deficiency.
