Twelve Taboos of Fertilizer Application
Today's editor will explain the common knowledge of flower cultivation, the "Twelve Taboos of Fertilizer Application". Next, the editor will introduce to everyone.
1. Avoid applying a single type of fertilizer. The ideal application method is to first apply organic fertilizer, then properly mix and scientifically apply nitrogen, phosphorus, and potassium fertilizers.
2. Avoid foliar fertilization at high temperatures in the afternoon. High temperatures in the afternoon cause rapid evaporation after spraying, and the liquid fertilizer is not easily retained on the surface of the plant, making it difficult for the stomata to absorb quickly.
3. Avoid shallow surface application of nitrogen fertilizer. Applying nitrogen fertilizer to the shallow surface layer can easily cause nitrogen to decompose and volatilize under sunlight.
4. Avoid applying excessive amounts of high-concentration fertilizers at once. Regardless of the type of fertilizer, if the dose is too large at once, it will cause the plant roots to "reverse absorb," resulting in root damage.
5. Avoid broadcasting fertilizers with water. For example, mixing monopotassium phosphate with urea and broadcasting it with water, as phosphorus and potassium have low mobility in the soil, the utilization rate of fertilizers applied with water is very low, and they basically remain on the surface soil.
6. Avoid using ammonia water and ammonium bicarbonate in greenhouses or conservatories. Because the ecological environment in greenhouses is in a high-temperature and closed state, these two types of fertilizers are very prone to volatilize and burn the plants in high-temperature enclosed conditions, affecting normal growth.
7. Avoid "blind matching." Regardless of the nature of the fertilizers, arbitrary mixing is not good. For example, mixing "ammonium nitrogen" fertilizer with alkaline fertilizers such as wood ash, lime, and phosphorus fertilizer will accelerate the volatilization of nitrogen, leading to fertilizer waste and easily burning the crops.
8. Avoid broadcasting or surface applying phosphorus fertilizers. Phosphorus has very low mobility in the soil, and broadcasting or surface application is easily adsorbed and fixed by the soil, greatly reducing the fertilizer effect of phosphorus.
9. Avoid applying excessive amounts of nitrogenous fertilizers to leguminous crops. Leguminous crops have root nodules, and if excessive amounts of nitrogen fertilizer are applied, it will directly affect the nitrogen-fixing activity of the root nodules.
10. Avoid applying excessive amounts of chlorine-containing fertilizers to sensitive crops. Sensitive crops such as tobacco, citrus, potatoes, and grapes must not be applied with excessive amounts of chlorine fertilizers at once, otherwise, it will affect the normal growth of the plants.
11. Avoid fertilizing before heavy rain. Because after fertilizing, if it encounters a暴雨 or shower, the fertilizer is easily washed away by rain, causing nutrient loss.
12. Avoid using micro-fertilizers as the main fertilizer. Micro-fertilizers such as zinc, molybdenum, boron, and rare earths have a good effect on plant "microelement deficiency," but avoid making "micro-fertilizers the mainstay," which can lead to malnutrition in the plants and hinder growth and development.
The above is a comprehensive explanation of the "Twelve Taboos of Fertilizer Application." I hope it can help you.
