Look at the season. The winter temperature is low, the plant growth is slow, most flowers are in a state of growth stagnation, generally not fertilized; spring and autumn are in the flower growth period, roots, stems, leaves grow, flower buds differentiate, young fruit swells, all need more fertilizer Appropriate topdressing should be applied; the summer temperature is high, the water evaporates quickly, and the flower plant grows vigorously. The concentration of applied fertilizer should be small, and the number of times can be more. In the seedling stage, some nitrogen fertilizer can be applied to promote the rapid and robust growth of the seedlings; in the bud stage, more phosphate fertilizer can be applied to promote the growth of large seeds; in the early stage of fruit setting, the fertilization is appropriately controlled to facilitate fruit setting.
Second look at the variety. Different varieties of flowers have different requirements for fertilizers, so different fertilizers should be applied. Such as sweet-scented osmanthus, Camellia, pig manure, avoid human waste; azalea, camellia, medlar and other southern flowers avoid alkaline fertilizer; need to re-cut the annual flower needs to increase the proportion of phosphorus, potassium fertilizer, in order to facilitate new technology; Leaf-based flowers can be applied to nitrogen fertilizers; flowers with large flowers, such as dahlias, chrysanthemums, etc., should be applied with appropriate amount of fertilizer during flowering to make all flowers open and beautiful; The flower should be properly controlled during the flowering period, and the full fertilizer should be applied to the fruit during the fruiting period to achieve the desired effect; the bulb flower, more potassium fertilizer, to enrich the bulb; the fragrant flower, enter the flowering period, more Phosphorus and potassium fertilizer can promote the aroma of flowers.
Third, look at the growth. Especially for potted plants, fertilization depends on the long-term use. Adhere to the principle of "four more, four less, four no", that is, yellow thin and multiple application, more application before germination, more gestation of buds, more application after flowering; less cultivation, less germination, less flowering, less rainy season The apprentice does not apply, the new plant does not apply, the summer does not apply, dormancy does not apply. At the same time, we should pay attention to the "four bogey": one avoids heavy fertilizer, two avoids raw fertilizer (application of organic fertilizer must be fully decomposed), three bogey hot fertilizer (high temperature in summer at noon, fertilization is easy to hurt the root), four bogey to take fertilizer, ie When planting flowers, do not place the roots directly on the base fertilizer at the bottom of the basin. Instead, add a layer of soil to the fertilizer and then plant the flowers into the pots.
In short, flower fertilization should be scientific and reasonable, should pay attention to timely, appropriate amount, can not be blindly abused.
