Nitrogen fertilization for foliage plants The nitrogen fertilization of foliage plants can make the leaves green, and can promote the growth of the branches and leaves of the plants, so that the plants grow more vigorously.
If the color of the leaves becomes lighter and the growth rate is slow, you can fertilize the plants. During the seedling stage, nitrogen fertilizer is the main factor, and thin fertilizer is applied frequently to promote plant growth. If it is an adult plant, the concentration of fertilization can be increased slightly. Nitrogen fertilizers cannot be applied side by side, and phosphorus and potassium fertilizers should be combined.
When applying base fertilizer to the plant, base fertilizer is mainly based on organic fertilizer. This fertilizer not only has fast fertilizer effect, but also improves soil structure and improves soil fertility. When topdressing plants, chemical fertilizers are the main method. This fertilizer has fast fertilization and is rich in nutrients, which is good for plant growth.
Applying N, P, and K fertilizers when fertilizing the plants, do not bias the application of nitrogen fertilizers, otherwise some plants will appear long. N, P and K fertilizers should be applied to the plants in a balanced manner.
Foliar fertilizer can be sprayed with some foliar fertilizer when the plant enters the period of vigorous growth or when the plant lacks trace elements. However, it should be noted that the fertilizer concentration must be low, otherwise leaf burns may occur.
Wet fertilization of the soil Fertilize the soil when it is wet. The soil has strong ability of absorbing and retaining fertilizer, which is conducive to plant growth. But it should be noted that do not fertilize on rainy days.
Cover the soil after fertilization After fertilizing the plants, pay attention to covering the soil, so that the fertilizer is not easy to volatilize, which is conducive to the maintenance of fertilizer efficiency.
Seven bogeys
New plants can not be fertilized for some newly transplanted plants, because there may be wounds on these plants. If fertilization, it is easy to cause wounds to be difficult to heal, root rot, and serious death.
Weak plants can not be fertilized. The diseased and weak plants grow poorly, the metabolism is relatively slow, and the absorption capacity of the fertilizer is relatively low. If fertilization is applied, it is prone to fertilizer damage.
During the flowering period, fertilization is carried out at the flowering stage of the plant. If the plant absorbs too many nutrients, it will be prone to become long, which will affect the plant's flowering and bud drop.
During the dormant period, the plant grows very slowly or even has stopped growing. At this time, fertilization can easily break its dormant period and allow the plant to start growing. The subsequent growth and flowering of the plant will be affected.
When fertilizing the root system, it is not possible to fertilize the root system directly, as it is easy to burn the roots. To fertilize, fertilize away from the root system.
If fertilizer is applied to the plants, it is easy to take away diseases and insect pests. Moreover, the heat generated by the fertilizer during the fermentation process can easily burn the plants, and even cause the plants to die.
When fertilizing plants, be careful not to apply thick fertilizers. Otherwise, it is easy to cause burns or even death. The best way is to apply thin fertilizer.
