First, the newly planted plants do not apply new plants and have many wounds. If they are stimulated by the outside world, they will not heal and will cause rotten roots.
Second, the flowering period does not apply the flowering period of fertilization, it will cause falling buds, falling flowers, falling fruit.
Third, do not apply flowers in the dormant period to stop or slow down growth during the dormant period, slow metabolism, poor photosynthesis, if the fertilizer is applied, it will soon break the dormancy, causing the plant to continue to grow, thus, it will consume more nutrients and affect the coming year. Flowering.
Fourth, the roots are not applied as the flower plants continue to grow, and its root system is gradually expanded accordingly. If fertilized under the roots, it is not conducive to full absorption and utilization. Therefore, depending on the growth of the plant, the hole should be applied to the appropriate place or the edge of the root to facilitate the absorption of the root.
5. Concentrate should not be applied to potted plants. The concentration should not be too large or too much, otherwise it will cause death. Generally, we should master the principle of “thin fertilizer and diligenceâ€, and it is best to use three-point fertilizer and seven-point water.
Sixth, can not apply fertilizer If the application of unfertilized fertilizer is not only easy to insects, oysters often emit odor and pollute the environment and encounter water will ferment, damage the roots of plants.
7. Fertilizer should not be applied only to nitrogen fertilizer, and should be combined with nitrogen, phosphorus and potassium. It is best to use farm fertilizers such as cake fertilizer, manure, compost, chicken and duck pigeon droppings, bone powder, leaves, and ash, such as nitrogen fertilizer. It is easy to cause the branches and leaves to prolong the growth period, delay flowering or not flowering, or the flowers are light and light.
8. Weak plants are weak, the branches of weak plants are weak, the photosynthesis is poor, the metabolism is slow, and “virtual is not supplementedâ€. If fertilized casually, it is easy to cause fat damage.
