Orchid fertilization method

1. Orchids are applied in farming season, and after a period of recovery, a new round of growth begins. When the temperature rises to 10, foliar fertilization can be carried out, which not only promotes the recovery of orchid plants, but also supplements the nutrients consumed in winter. After that, according to the growth of orchid plants, foliar fertilization is carried out regularly or irregularly, and orchid plants begin to sprout at the turn of spring and summer. At this time, root fertilization can promote rapid development and multiple buds. Fertilizer is mainly nitrogen, which can be diluted with organic liquid fertilizer or chemical fertilizer. In autumn, orchid plants enter the reproductive growth period, some differentiate flower buds, some are breeding buds, and fertilization should be based on phosphorus and potassium. Winter fertilizer should be applied in late autumn and early winter, including solid fertilizer and high concentration liquid fertilizer, which not only enhances the cold resistance of plants, but also lays a good foundation for the coming year. In midsummer and severe winter, most orchids are dormant and fertilization should be stopped.

2. According to the growth period of orchids, the growth period of orchids is seedling stage, vegetative growth stage, reproductive growth stage and flowering stage. Different periods and tasks require different fertilizers. The seedling stage includes germination, rooting and leaf spreading, and the required nutrition is mainly nitrogen. 0. 1% urea solution or 1:20~50 times organic liquid fertilizer can be applied in the pot, but care must be taken not to splash the fertilizer solution on the center of the bud and damage the bud. During the vegetative growth period, full-price fertilizer can be applied, both organic and inorganic, or alternatively, with complementary advantages. During the reproductive period, phosphorus and potassium fertilizers are mainly applied to promote the differentiation of flower buds, and the flowers are big and fragrant.

3. Different orchid varieties have different nutritional requirements according to different uses. If the amount of fertilization is the same, some will be insufficient and some will be excessive. Generally speaking, orchids have narrow leaves and thin roots, which require less fertilizer and can be applied less. Cymbidium hybridum and Cymbidium hybridum plants are medium in size and medium in fertilizer requirement, so normal fertilization is appropriate. Cymbidium has long leaves, wide leaves and strong roots, so it needs more fertilizer, so it needs more fertilizer. The plant height, leaf length and leaf width of Cymbidium hybridum, Cymbidium hybridum and Cymbidium hybridum need more fertilizers, so more fertilizers should be applied. Line art, crystal, spot art orchid and weak new exotic orchid plants must be carefully fertilized, so that less should not be more, light should not be coarse. If raw fertilizer, concentrated fertilizer or excessive fertilizer is applied, it will not only be vulnerable to fertilizer damage, but also be seriously ruined.

4. According to the growth of orchid seedlings, for various reasons, some orchids grow vigorously and some orchids grow weakly. Fertilization must vary from orchid to orchid, and it is not equal to the same amount. Strong people should be diligent and pay more; General growth, according to the normal fertilization; The amount of fertilization with poor growth should be less, the concentration should be smaller and the interval should be longer. Weak plants, diseased plants, plants just coming down the mountain and plants just coming to the basin are not suitable for fertilization. Vulnerable plants, downhill plants and new potted plants can be fertilized on the leaves first, and then fertilized on the roots after a period of maintenance.

5. According to the soft and hard application of planting materials, soft planting materials generally contain organic matter and various nutrients, and do not need too much topdressing; Some hard plants contain a single element, some contain no nutrients, and all rely on topdressing to provide nutrition. Moreover, soft planting materials are easy to absorb, while hard planting materials are poured from above and flow from below, so it is difficult to penetrate. It needs to be applied by bubble basin method or circulation method to be effective.

Other information, such as the size of the orchid basin and the number of orchid seedlings, should also be properly grasped, and egalitarianism should not be engaged.
