There are differences in fertilization of orchids

The orchid is also known as the tropical, subtropical epiphytic orchid. The flowers are large in color and beautiful in color. The leaves are green and beautiful. The flowering period lasts several months. It can be cultivated without soil, and organic fertilizer is not used. It is clean and suitable for indoor potted viewing. For several years the main varieties of thistle flower. The prospects for the current introduction of cultivation and breeding in our province are very promising. Due to the large number of orchid species, the fertilization methods for several major varieties are now introduced as follows for planters and family flower growers. There are three methods for fertilizing Calendula officinalis fertilizer: First, the fertilizer is proportioned well and mixed with the planting material for its growth and development; Second, the prepared fertilizer is poured into the solution in divided doses. Third, the prepared fertilizer is made into solid granules or fertilizer blocks, which can be applied to the pot surface. In sunny seasons, more fertilization is needed to ensure the vigorous growth of orchid plants, while in dark, cold or rainy weather, fertilization should be reduced or no fertilization at all. Phalaenopsis orchids need less fertilizer, generally should master the principle of "fat fertilizer, a small amount, and diligence." Mainly grasp the following aspects: Spring and summer is a vigorous growth period, which can be applied once a week with nitrogen-based thin liquid; autumn and winter for the flower stem growth period, should be applied once every 10 to 14 days of phosphorus and potassium fertilizer-based thin liquid fertilizer . It is also possible to use a 0.5% superphosphate aqueous solution; after budding, it is necessary to stop fertilization, otherwise it is easy to fall off early buds. Cymbidium grandiflora is one of the most fertile varieties of orchids. It should be followed by thin fertilizers (cake and water) every two weeks during vigorous growth, or solid fertilizer in spring and summer. Into the basin side of the matrix, slow-release nutrients, long-term absorption of the root system. In the seedling stage and the low temperature season, little or no organic fertilizer should be applied. The nitrogen, phosphorus and potassium compound fertilizer with a ratio of 7:6:19 can be used for foliar fertilizer application. The effect is very good. Dendrobium Dendrobium is fertile but fertilization is required. The seedling stage should be applied with a high nitrogen-containing diluted fertilizer solution with a concentration of 20%, which is applied once a week. After the seedling stage, the growth of plants was accelerated, and nitrogen, phosphorus and potassium nutrients could be topdressed once every 2 weeks for a thinner liquid fertilizer. The concentration was 20%, and it must not be splashed on the leaves. The proper amount of Cattlelancautlan fertilizer can make seedlings grow robustly and beautifully. The method is as follows: 1, should apply light fertilizer. Its concentration is 50%-80% of the general flower and vegetable fertilizer. The new shoots can be fertilized after being unearthed for 1 week, and the young seedlings should adhere to the principle of “a small amount and diligence”. 2, during the growth period can be applied every 10-15 days 1 cooked very thin pancake fertilizer water. Pay attention when applying fertilizers. Do not apply to the leaves or buds. Or evenly sprinkle the fermented, very thin pancakes to absorb them in the pots every month. 3, orchids that have been flowering age, in the flower bud differentiation period should be appropriate to apply more phosphorus and potassium fertilizers, in order to raise roots to help flowers, improve the efficiency of photosynthesis, and promote tough leaves. Paphiopedilum requires less fertilizer, and it can only be fertilized during the growing season. After sprouting in the growing season, a thin pancake can be applied every 3-4 weeks, and a small amount of flower buds can also be applied evenly in the pot to make Ye Maohua Yan. Dormant fertilization should be stopped to make it fully dormant.
