Qiyi:
(1) Classification and fertilization. The foliage flower should be applied with nitrogen fertilizer to make the leaves fresh and crisp; the flower and flower should be applied with phosphorus and potassium fertilizer to make the plants bloom early and have early results; the bulb flower should be applied with potassium fertilizer to enrich the bulb.
(2) Apply fertilizer at the right time. Fertilization is most appropriate when it is found that the leaves of the flowers become lighter and the growth slows down. According to the different growth stages of flowers, different fertilizers and different amounts are applied. For example, the nitrogen fertilizer is mainly applied in the seedling stage, and the thin fertilizer is applied to promote the rapid and healthy growth of the seedlings; after the seedlings, the fertilization concentration can be appropriately increased. And increase the application of phosphorus and potassium fertilizer.
(3) Matching with base fertilizer and topdressing. The base fertilizer is mainly organic fertilizer, which is stable and stable for fertilizer, and can improve soil structure and physical and chemical properties and improve soil fertility. Topdressing is mainly based on chemical fertilizers, which has the characteristics of more nutrients, quick fertilizer efficiency and high fertilizer intensity. It is a necessary supplement for base fertilizer.
(4) Apply nitrogen, phosphorus and potassium fertilizers. For example, partial application of nitrogen fertilizer is prone to cause branches and leaves, delaying flowering or not flowering; partial application of phosphate fertilizer will inhibit the absorption of nitrogen and potassium, causing poor growth of plants, and easily lead to iron deficiency and zinc deficiency; partial application of potassium fertilizer will inhibit plants. The vegetative growth and the occurrence of magnesium deficiency.
(5) Foliar fertilizer is applied as appropriate. In the vigorous growth period of plants or the lack of trace elements, spraying foliar fertilizers as appropriate can timely supplement the lack of nutrients in the roots of flowers. However, foliar top dressing should strictly control the concentration to avoid burning the leaves.
(6) Fertilize when the soil is wet. When the soil is fertilized, it is easy to cause the physiological loss of water and leaves of the flowers and leaves, and it will cause the plants to die. On the contrary, fertilization in rainy days, due to high soil water content, poor ability to absorb fertilizer and protect fertilizer, easy to be washed away by rain, and will cause the plants to grow.
(7) Appropriate amount of soil after fertilization. Many people are used to applying fertilizer to the topsoil, which not only makes it easy to lose the fertilizer, but also burns the roots, especially in hot and dry weather, which evaporates faster and the roots are heavier. Therefore, after fertilization, the amount of soil should be covered to prevent loss of fertilizer and improve fertilizer efficiency.
Seven bogeys:
(1) Fertilize new plants. The new plant has many root wounds. If it is stimulated by the outside world, the wound will not heal easily, causing rotten roots and even causing plant death.
(2) Fertilize weak plants. Weak plants have weak growth potential, poor photosynthesis, slow metabolism, and low absorption capacity for fertilizers. If they are fertilized casually, they will easily cause fertilizer damage.
(3) Fertilization during flowering. Fertilization during flowering will promote the vegetative growth of the plant, which will easily cause the growth of the buds and falling flowers.
(4) Fertilization during dormancy. When the flower is stopped or slowed down during the dormant period, if the fertilizer is applied, the dormancy will be broken, and the plant will continue to grow, which will affect the flowering in the coming year.
(5) Fertilization under the roots. When planting flowers, the roots of the plants should not be placed directly on the base fertilizer, but a layer of soil should be added to the fertilizers, otherwise it will not only be beneficial to the full absorption and utilization of the fertilizer, but also easily damage the root system. In addition, the topdressing should be based on the growth of the plant, and the hole should be applied to the roots to facilitate the absorption of the roots.
(6) Apply fertilizer. Applying unfertilized organic fertilizer to flowers is not only easy to spread pests and diseases, but also organic fertilizers ferment and heat in the process of decomposing, burning roots of plants.
(7) Apply concentrated fertilizer. To fertilize flowers, we must strictly control the amount of fertilization. Avoid excessive concentration or excessive dosage. Otherwise, the roots of the plants will be burned, causing death in severe cases. Generally, “thin fertilizer should be appliedâ€.
