Fertilization of Vegetables "Three Noes"
There are many kinds of vegetables, and the demand for nutrients varies from vegetable to vegetable. Different types of vegetables have different requirements for nutrients. Fertilization is a prerequisite for ensuring normal growth of vegetables. If fertilization is improper, it will cause stagnation of vegetable growth and even cause vegetable death. Some fertilizers also cause residues. , causing harm to the human body. Therefore, pay attention to the following points when fertilizing: First, do not water after applying urea The nitrogen component contained in urea is amido-ammonium nitrogen, and the amido-ammonium nitrogen is converted into ammonium carbonate or ammonium bicarbonate by the action of urease secreted by soil microorganisms before it can be absorbed and used by vegetable roots. If the urea is watered immediately after it is applied or rain is encountered, ammonium nitrate will be lost. Therefore, regardless of whether the basal fertilizer or top dressing of vegetables, urea should be 5 to 6 days after application, so that all the conversion and then watering, so as to avoid losses. Second, do not repeatedly apply ammonium sulfate In an acidic or calcareous vegetable field, if ammonium sulfate is applied multiple times in succession, the soil will become more acidic and the calcareous soil will be hardened, resulting in poor growth and development of the vegetables, and the quality and yield will be reduced. Economic benefits. Third, do not apply ammonium bicarbonate when water shortage in vegetable fields Ammonium bicarbonate is extremely unstable in its chemical properties and is easily volatile. When applying ammonium bicarbonate in vegetable fields, regardless of whether it is used as a base fertilizer or as a top dressing, deep application should be carried out in the case of wet vegetable fields, and the soil should be covered immediately after application. If the weather is dry, and it is not possible to use ammonium bicarbonate, dilute with water or apply watering. Sweet corn.
