Fertilization is an important technical measure for flower production. In order to obtain high-quality flower products of Huayan Yemei in time, it should be considered according to the characteristics of the fertilizer, the different growth stages, the depth of the root system and the characteristics of soil, climate and market demand. To scientific fertilization, improve fertilizer utilization. Wooden Door Designs,Door Wood,interior door sizes Jiekai Industrial And Trading Co., Ltd. , http://www.gosdoors.com
Scientific fertilization technology of flowers
First, according to different growth stages of flowers, staged fertilization,
1. Fertilize according to the principle of physiological balance. Different flower species have different biological characteristics and fertilizer characteristics, so the fertilization requirements are also different. In addition to the large amount of nitrogen fertilizer, phosphorus and potassium fertilizers should also account for an important proportion of flowers (such as gold, grapes, etc.) with the main product. The flower mainly based on foliage is applied with potassium fertilizer on the basis of applying nitrogen fertilizer. The flower mainly based on flower viewing is biased with nitrogen fertilizer, combined with phosphorus and potassium fertilizer, and attention is paid to the application of trace elements and rare earth fertilizers. In the process of fertilization, it is necessary to emphasize the balance and cooperation between various elements in order to give full play to the maximum yield increase of fertilizer.
2. Fertilize according to different growth and development stages of flowers. The same flower, in different stages of growth, the demand for nutrients is also very different, and it needs to be fertilized in stages. For example, perennial flowers, when the seedlings are in the fast-growing stage, are just the long root group, the hair branches and leaves, and the high growth period. At this time, the nutrient consumption is particularly high, and special attention should be paid to fertilization. Among them, the proportion of nitrogen fertilizer is the largest, and it is combined with phosphorus and potassium fertilizer. If you can fully supply all kinds of nutrients in this period, the flowers will flourish and lay a foundation for flowering. Â Â Â
3. Fertilize according to different growing seasons. In the same flower species, in addition to different requirements for the supply of fertilizer at different growth stages, different growth seasons have different requirements during the year. During the year, the roots of the early spring roots are restored before growth and before the fall leaves are dormant, and the fertilizer is applied. Nitrogen fertilizer is very beneficial to root growth. During the spring germination and flowering stage, the flower needs to absorb more nitrogen fertilizer to ensure the vegetative growth is vigorous, but it should not be too early. If it is too early, the root system has not fully recovered from normal growth, and the absorption is poor. The fat content is easy to lose. At this time, the root system is young. If the soil solution concentration is high, it is easy to cause root burns. After entering June, many woody flowers begin to divide flower buds. At this time, nitrogen fertilizer should be controlled to ensure the supply of phosphorus and potassium fertilizer. Â Â Â
   Second, according to flower growth habits and ornamental characteristics, fertilizing
   Under the premise that the plants are not long and do not affect the cold resistance ability, the nitrogenous fertilizer can be applied in the growing season to promote the flourishing foliage and the green color of the leaves, and enhance the ornamental. In the early spring flowering category, it should ensure that the base fertilizer supply is sufficient in winter, making it a large and large flower. In the flower species that bloom many times a year, in addition to the base fertilizer in the dormant period, the nutrients consumed by the shoots and flowering should be replenished in time after each flowering to ensure the normal opening of the next flower.
   Third, according to the characteristics of fertilizer fertilization
   Some fertilizers have a special role and should be treated separately. For example, boron fertilizer can promote root growth, increase the strength of flowering knots, and enhance cold resistance; quicklime can reduce soil acidity and improve soil structure. It is an important fertilizer in the acid red soil region of southern red and yellow soil, and it can also make clay loose; It can promote photosynthesis and can compensate for the negative consequences of insufficient light and low temperature in winter greenhouses.
