Fertilization of flowers should be reasonable and methods of fertilization of flowers should be reasonable.
With the improvement of people's living conditions, every household will basically plant some flowers and plants at home. If you want these flowers to bloom beautifully, you should understand their habits and master their fertilization methods. So how should flowers be fertilized? Today, the editor would like to share with you that the "three looks" of flower fertilization refer to those.
Look at the season. Winter temperature is low, plant growth is slow, most flowers are in a state of stagnant growth, generally do not apply fertilizer; spring and autumn are in the peak period of flower growth, root, stem and leaf growth, flower bud differentiation, young fruit expansion, all need more fertilizer, should be more topdressing; high temperature in summer, fast water evaporation, and flower plant growth peak period, the concentration of topdressing should be small, the frequency can be more. More nitrogen fertilizer can be applied at the seedling stage to promote the rapid and robust growth of seedlings; more phosphate fertilizer can be applied at the bud stage to promote large flowers and seeds; fertilization can be properly controlled at the initial stage of fruit setting to facilitate fruit setting.
Second, look at the variety. Different varieties of flowers have different requirements for fertilizer, so different fertilizers should be applied. For example, sweet-scented osmanthus and camellia like pig manure and avoid human feces and urine; southern flowers such as rhododendron, camellia and gardenia avoid alkaline fertilizers; flowers that need to be re-cut every year need to increase the proportion of phosphorus and potassium fertilizer to facilitate the germination of new techniques; flowers with large flowers, such as dahlias and chrysanthemums, should apply an appropriate amount of complete fertilizer during flowering in order to make all flowers bloom and beautiful. In order to achieve the expected effect, the flowers dominated by fruit should properly control the water supply during the flowering period and apply sufficient complete fertilizer in the strong fruit period; bulb flowers, apply more potassium fertilizer to enrich the bulb roots; fragrant flowers, enter the flowering stage, apply more phosphorus and potash fertilizer, can promote the strong fragrance of flowers.
Third, look at the growth. Especially for potted flowers, fertilization depends on the growth rate. Adhere to the principle of "four more, four less, four noes", that is, more application in yellow and thin, more before germination, more in pregnant buds, more after flowering, less in sturdiness, less in germination, less in flowering, less in rainy season, no application in summer, no application in summer, no application in dormancy. At the same time, we should pay attention to the "four taboos": first, avoid concentrated fertilizer, second avoid raw fertilizer (the application of organic fertilizer should be fully mature), third avoid hot fertilizer (high soil temperature at noon in summer, fertilization is easy to hurt roots), and fourth avoid sitting fertilizer, that is, when planting flowers, do not put the root directly on the base fertilizer at the bottom of the pot, but add a layer of soil to the fertilizer, and then plant the flowers in the pot.
