In addition, combined with the arrangement of You Lan,
The following focuses on fertilizer, water and light for orchid cultivation.
Fertilize soil or land
Although orchids are cultivated by orchid mud, the nutrient area in the basin is limited, so it is very important to supplement nutrients in the long term. No fertilization, more fertilization and then fertilization. Cymbidium grows in a pot, and the soil in the pot is too fat to survive. Even if it can survive, it rarely blooms. If there is too much fertilizer in summer, leaves will flourish in autumn, which often leads to poor flowering of leaves in the next spring. If there is too much nitrogen fertilizer and leaves are too fat on weekdays, the growth and nutrition of leaves and flowers will be unbalanced, and only long leaves will not bloom. How to apply fertilizer properly? Generally speaking, leaves and buds are new, and a small amount of light liquid fertilizer can be applied. It is more suitable to apply fertilizer once every half a month to three weeks before the new grass is unearthed in May and before beginning of autumn. It is necessary to master the principle of applying more thin fertilizer, applying fertilizer at vernal equinox and autumn equinox, and applying fertilizer 20 days after the flower withers. It is best to apply fertilizer at night and water it again the next morning. The safer method is to apply fertilizer according to the depth of leaf color. Yellow and thin leaves are lack of fertilizer and should be topdressing; Black leaf tip scorched is excessive fertilization, so fertilization should be stopped. Usually effective liquid fertilizer is to cook wheat or soybean or mash mussels, fish and shrimp, soak them in water for several months until there is no odor, and add 8-9 times of water to use them. Fermented and decomposed human excrement, bone meal, cake fertilizer, etc. It can also be applied, and the ratio of fertilizer to water is about 10%.
water
As the saying goes, "Dry orchids wet chrysanthemums". Blue flowerpots should not be too wet, as long as they are kept wet, 80% dry and 20% wet is the best. Water according to the degree of dryness and wetness of the basin soil and the growth of bluegrass. The new grass has not been unearthed in April-May, so it should be put on a basin to dry to prevent the new buds from rotting. June-September is the season of vigorous growth of new grass. At this time, the temperature is high and the evaporation is large, so it is necessary to increase the amount of watering (don't water around noon). When it turns cold in autumn, the watering amount should be reduced as appropriate to keep the basin soil moist. In winter, we should control the amount of water, and the water must be dried, not splashed with cold water. It is wise to water around noon. Water should be injected from the edge of the basin, not from the head. The water used is rainwater and spring water, including river water, river water and tap water, and well water is the most taboo. All kinds of water should be taken out of the water storage tank for one day, so that the sewage in the water can precipitate, chlorine can escape, and the water temperature is normal, and then it can be poured out. Orchids also have certain requirements for air temperature. In summer, besides watering, the ground should be watered or sprayed. Orchids can get wet with light rain, so avoid continuous rain or heavy rain, otherwise the heart and leaves will rot easily, so get up and cover them when it rains in the middle of the night, especially in rainy season.
illuminate
Although orchids like shade, if they are kept in a cool place all the year round, they will also affect flowering. In spring and summer, it is best to shade the sun with reed curtains or put them in indoor windows facing east and south. Orchids under the curtain should be rotated once every half a month, so that they can be exposed to light on all sides and grow in a balanced way. In cool autumn, remove the basin from the shade and bask in the sun for half a day. When it is cold, put it under the indoor window for the winter. The temperature should be kept at 1℃-2℃, not too warm or frozen.
I have cultivated orchids 10 years, and I often review them according to this orchid. In addition to these, combined with my own experience, the introduction of 1 is the most critical. I would rather spend more money to introduce strong seedlings than buy weak seedlings at low prices. Environmentally, orchids need humidity, good ventilation and proper illumination. 3 Planting materials, it is recommended to use appropriate amount of planting stone, clay, fairy soil, snake wood and sand. 4 water control, novices have a 27 watering method. When the temperature is above 25 to 30 degrees, water should be poured once every two days and sprayed once in the morning and evening. When the temperature is between 15 and 25 degrees, water should be poured every seven days. When the temperature is lower than 15 degrees, it is about once every half month, and when it is lower than 10 degrees, a little moist soil should be poured as appropriate. If you do this well, orchids will not be difficult to raise.
