Flowers in different seasons of sowing points, flowers scientific fertilization methods

Many people like to plant flowers, in order to make their own culture of flowers luxuriant foliage, colorful, fertilization is a very important link, China Agricultural Technology Network for you to introduce scientific fertilization methods.

Look at the seasons. Winter temperature is low, plant growth is slow, most flowers are in a state of growth stagnation, generally do not fertilize; spring, autumn both hands are flower growth peak period, root, stem, leaf growth, flower bud differentiation, young fruit expansion, all need more fertilizer, should be appropriate more topdressing; summer temperature is high, water evaporation is fast, but also flower plant growth peak period, topdressing concentration should be small, frequency can be more. Seedlings can apply more nitrogen fertilizer to promote rapid and healthy growth of seedlings; bud stage can apply more phosphorus fertilizer to promote large flowers and strong seeds; early fruit setting appropriate control of fertilizer to facilitate fruit setting.

Second, look at the variety. Different varieties of flowers have different requirements for fertilizer, so different fertilizers should be applied. Such as osmanthus, camellia like pig manure, avoid human excrement; azalea, camellia, gardenia and other southern flowers avoid alkaline fertilizer; flowers that need to be re-cut every year need to increase the proportion of phosphorus and potassium fertilizer to facilitate germination of new techniques; flowers based on foliage can be biased towards nitrogen fertilizer application; flowers with large flower types, such as dahlia, chrysanthemum, etc., should apply appropriate amount of complete fertilizer during flowering period to make all flowers open and beautiful; For flowers with fruit as the main fruit, water supply should be properly controlled during flowering period, and sufficient complete fertilizer should be applied during strong fruit period to achieve the expected effect; for bulbous flowers, more potassium fertilizer should be applied to enrich the bulbous roots; for fragrant flowers, more phosphorus and potassium fertilizer should be applied during flowering period to promote flower fragrance.

Third, look at the growth. Especially for potted flowers, fertilization depends on the growth rate. Adhere to the principle of four more, four less and four no, that is, more fertilizer for yellow thin, more fertilizer before germination, more fertilizer for pregnant buds and more fertilizer after flowering; less fertilizer for healthy growth, less fertilizer for germination, less fertilizer for flowering and less fertilizer for rainy season; no fertilizer for excessive growth, no fertilizer for new planting, no fertilizer in hot summer and no fertilizer for dormancy. At the same time, attention should be paid to four taboos: one taboo thick fertilizer, two taboo raw fertilizer (application of organic fertilizer to be fully decomposed), three taboo hot fertilizer (summer noon soil temperature is high, fertilization is easy to hurt the roots), four taboo sitting fertilizer, that is, planting flowers can not directly put the roots on the basal fertilizer at the bottom of the pot, but add a layer of soil on the fertilizer, and then plant the flowers into the pot.

In short, flower fertilization should be applied flexibly according to the types and growth conditions of flowers. Notable is around noon when the temperature is higher should not fertilize, change pots or transplant flowers should be applied fertilizer.
