What factors should be paid attention to in flower fertilization? How to fertilize flowers

Flower fertilization is different from crop fertilization, flower fertilization should pay attention to a lot of aspects, a little negligence, it is possible that flowers wither and die. Therefore, flower fertilization must grasp all aspects of factors, the following with the editor together with a detailed understanding of it.

The key to do a good job of fertilization is to achieve timely and appropriate amount. At the right time, it is necessary to apply fertilizer when flowers need fertilizer. For example, it is found that the leaves of flowers become lighter and the plants grow weakly and slowly, and fertilization is like sending charcoal in the snow, which is the most timely. This can be used as an analogy to eating. When you get food in your stomach, you will eat very delicious, and it will be good for your health. On the contrary, if you eat a lot of food when your stomach is full or when you are about to sleep, it is not only bad for your health, but also harmful to your health. An appropriate amount, that is, the amount of fertilizer applied should be well controlled, and too little fertilizer will not work; if you apply too much, it will not only fail to achieve the goal, but will burn the flowers to death. It should also be noted that flowers should be applied nitrogen fertilizer at the seedling stage, which can promote the rapid and robust growth of seedlings, and phosphate fertilizer should be applied at flowering stage to facilitate flowering.

Fertilization must also pay attention to the relationship between seasons, spring and summer, flowers grow fast and exuberant, can be more fertilization; people after autumn flower growth is slow, should be less fertilization; in winter, there is no need to apply fertilizer. It is also important to master the number of fertilization, potted flowers, the number of fertilization, but each time the amount should be less, must not be too much, too thick. During the period from the Beginning of Spring to the Beginning of Autumn, thin fertilizer and water can generally be applied every two weeks; the Beginning of Autumn can release thin fertilizer and water once every three weeks; the Beginning of Winter does not have to apply it again.

The time of fertilization can be carried out in the evening, it should be paid special attention to, the hot season can not be fertilized around noon, because during this period the soil temperature is very high, fertilization is easy to hurt the root. In addition, before watering, it is best to loosen the basin soil, which is conducive to the smooth infiltration of fertilizer and water and is absorbed by the roots of the plant.

Chemical fertilizers such as ammonium sulfate (nitrogen fertilizer), calcium superphosphate (phosphate fertilizer), potassium sulfate (potassium fertilizer), etc., are suitable for garden flowers. Potted flowers should not be often applied, otherwise for a long time, the pot soil will become harder and harder until hardened.

Fertilization should also be applied according to the variety of flowers. The fertilizers used cannot be the same. Such as sweet-scented osmanthus and camellia like pig dung. Avoid human urine; camellia, rhododendron, gardenia and other flowers native to the south, avoid alkaline fertilizer; flowers that need to be pruned every year, it is appropriate to increase the proportion of phosphate and potash fertilizer. Flowers mainly watching flowers, such as chrysanthemum and dahlia, need to apply appropriate amount of nutritious and comprehensive fertilizer in the flowering period in order to make the flowers beautiful in color; flowers mainly viewing leaves should pay more attention to applying nitrogen fertilizer; flowers mainly viewing fruits should appropriately reduce fertilizer and water during flowering period, while fully nutritious and comprehensive fertilizer should be applied in the period of strong fruit. Bulb flowers, it is appropriate to apply more potash fertilizer, in order to enrich the bulbs; fragrant flowers, into the flowering period should be applied phosphate fertilizer, potash fertilizer, in order to promote the strong flavor of flowers. When using organic fertilizer, you must not use unfermented raw fertilizer. You must wait until it is fully mature and add water to make it thin. For chemical fertilizers, we must strictly control the dosage, rather less than more, rather sparse than thick, otherwise it is very easy to burn the flower roots and lead to death.

Some experts who have many years of experience in growing flowers have summed up a set of practical essentials for fertilization. That is, "four more, four less, four discord and three taboos". "Siduo" means more fertilizer for yellow and thin, more before germination, more at bud stage, and more after anthesis; "four less" means less application for fat, less for germination, less for flowering, less for rainy season; "four nots" means nothing for growth and no application for new planting. If you are not in the heat of summer, you will not be dormant. " "three taboos" is a bogey of concentrated fertilizer, a taboo of hot fertilizer (refers to fertilization when the soil temperature is very high around noon in summer), and three taboos sit fertilizer (refers to planting flowers directly on the base fertilizer at the bottom of the pot, but should be separated by a layer of soil on the base fertilizer).
