Friends who love green plants will inevitably encounter such a problem. How do you give the beloved flowers fertilization, fertilization techniques and precautions? The techniques of fertilization include: Pay attention to timely and appropriate amounts. The so-called timely, refers to when the flowers need to be applied, such as the discovery of the pale leaf color of the flowers, plant growth is weak, fertilization is timely. Whenever fertilizer is applied, it depends on the different stages of growth and development of the flowers. For example, some nitrogenous fertilizers may be applied at the seedling stage to promote the rapid and robust growth of the seedlings; some of the phosphate fertilizers may be applied during the buds to promote flower buds Early control of fertilization is appropriate for fruit set in favor of fruit set. No matter what period of fertilization should pay attention to appropriate amount, if too much nitrogen fertilizer, easy to form leggy; too much potash fertilizer, hinder fertility, affect the flowering results. Several points of fertilization technology:
A, fertilization should pay attention to the types of flowers. Different types of flowers have different requirements for fertilizers. Such as sweet-scented osmanthus, camellias like pig manure, avoid human urine; rhododendron, camellia, gardenia and other southern flowers bogey alkaline fertilizer; flowers that need to be cut every year need to increase the proportion of phosphorus, potassium, in order to facilitate the emergence of new shoots; The foliage-dominated flowers can focus on the application of nitrogenous fertilizers; the flowers of large flowers (such as chrysanthemums, dahlias, etc.) need to be applied with adequate amounts of complete fertilizer at the flowering stage, in order to make all the flowers open and beautiful in shape; The flowers that are dominated should have adequate fertilizer and water control at the flowering stage, and adequate fertilizer should be applied during the fruit period in order to achieve the desired effect. For bulbous flowers, some potassium fertilizer should be applied to enrich the bulbous roots; fragrant flowers should enter the flowering stage. Apply more phosphorus and potash to promote flower fragrance.
B, fertilization should pay attention to the season. In winter, the temperature is low and the plants grow slowly. Most flowers are in a stagnant state and generally do not fertilize. In spring and autumn, the flowers grow vigorously. The growth of roots, stems and leaves, the differentiation of flower buds, and the expansion of young fruits all require more fertilizer. Appropriately more topdressing should be done; high summer temperatures, rapid evaporation of water, and flower growing season, the top dressing concentration should be small, the number can be more.
C. The application of organic fertilizer must be fully decomposed and raw fertilizer must not be used. On the other hand, there are many valuable suggestions on how to fertilize potted plants. For example, data from Jiangsu and other places indicate that fertilization depends on growth and dosage, and adheres to “more than four, four less, and four notâ€. That is, there are more yellow and thin plants, more planting before germination, multiple planting buds, and multiple planting after anthesis. ; vigorous and less applied, germinate less, flowering less, the rainy season less; long not instructed, new planting not, Sheng Shu not Shi, do not sleep. At the same time also pointed out that potted fertilization has three bogey: a bogey concentrated fertilizer, bogey thermal fertilizer (high soil temperature at noon in the summer, fertilizer easy to hurt the root), three bogey sit fertilizer, planting flowers when the basal basal fertilizer, can not be placed directly on the root Fertilizer, but to add a layer of soil on the fertilizer, and then planted flowers into the pot.
In addition: fertilization by light fertilizer Qin Shi (less applied Shi Qin Shi) is appropriate, do not apply concentrated fertilizer, raw fertilizer, dormancy period, flowering period, hot periods do not fertilize. General fertilization can be divided into three methods: acupuncture, pouring, and spraying. Acupuncture is used to dig a granular fertilizer around the plant to apply a hole. Pay attention to fertilization when pot soil is wet or water immediately after application. The method of casting with fertilizer dilution in the potting soil of the plant can be done, but when the potted soil is slightly dry, the fertilizer concentration should be light; the spraying method is to spray the chemical fertilizer at the concentration of 0.2-0.3% and spray on the foliage. On it, take care not to spray rain and spray water after spraying.
