Orchid florescence management (senior Lanyou experience)

During the period from stamen to full bloom, orchids must be carefully controlled and managed, and the necessary manual modifications must be carried out, otherwise it is difficult to achieve tall and straight flowers and beautiful appearance. And the same variety due to improper management of light, temperature and humidity caused rough flowers, abnormal spirit, rhyme and color, or excessive nutrient consumption due to blooming for too long, affecting the normal development of leaf buds and flower buds in the future. It not only involves the technical problems of daily training and management, but also a kind of artistic skill. The details are as follows:

First, most orchids budded after "the Beginning of Autumn". During the the Beginning of Autumn season, most parts of China were still in a period of high temperature, with a temperature of about 32-35 degrees during the day, high temperature and humidity, and abnormal muggy heat. Laner suffered a lot. Therefore, orchid cultivation must also take shading, ventilation, cooling, and heat prevention as the top priority, and those unearthed with flower buds should be sprayed with insecticides once or twice, in order to prevent the invasion of thrips and ensure the first level of normal management in the future. When the orchid stamens, such as orchid frail, disease or autumn stamens in late autumn, can not be retained. In the old grass after the dragon {old false bulb} between the stamens, it is appropriate to choose only a strong and full one, such as the former dragon (the new false corm of the next year) has flowers, it is better to keep the stamens of the former dragon, and remove the stamens of the former dragon. If extruded askew or give birth to stamens on one side of the basin should not be retained. After the flower buds of precious orchids are unearthed, if there are too many flower buds, strong buds should be left, and the rest of the thin flower buds should be removed, leaving 2-3 flower buds in each pot. If there are too many flower buds, it will affect the opening product. It will not only make the flowers bloom badly, but also consume too much nutrients of the maternal parent to affect the flowering next year. In general, orchids do not cut off flower buds.

Second, after "White Dew", the weather turned cool and most of the new grass grew. At this time, bluegrass can shine more sunshine, but also apply a little more phosphorus and potassium fertilizer and multi-element organic fertilizer to make the orchid plant accumulate more nutrients, make the buds full, full of spirit when the flowers bloom, and have a good aroma. The aroma of flowers comes from plant sugars, while model substances come from phosphorus, potassium and other elements. Therefore, we should pay attention to not partial nitrogen fertilization in this season, spray more phosphorus and potassium fertilizer, so that the plant growth of Lilan is stronger but not crazy, and it also lays a solid foundation for the growth period of spring in the coming year. The room temperature of overwintering orchids should be controlled at 5: 15 ℃. If the room temperature is too low, it will not play the role of preventing cold and keeping warm. Too high will also affect the dormancy of orchids. But for winter cold orchid and ink orchid should keep the room temperature a little higher, but not more than 15 ℃. If the room temperature is too high, the flower stem grows slowly and the flower bud develops poorly, which is easy to make the formed flower bud shrink and die. For hardy orchids, a low temperature of about 3-4 weeks and 0 ℃ is needed to complete the function of spring dormancy and vernalization, and then spring orchids can blossom well. Therefore, it is most suitable for Cymbidium to overwintering at 3-8 ℃. All potted orchids with buds should be placed on the platform near the glass window to facilitate more sunlight, and vegetarian flowers can be raised in the shade. For example, early blooming varieties of spring orchids cannot be exposed to direct sunlight when the stamens reveal the "chicken beak". Cold orchid and new year orchid are not affected. In late winter and early spring, if the indoor temperature and humidity are suddenly high and the periphery of the bowl is covered with water vapor droplets, ventilation should be strengthened in time. In the daily watering process, it is especially necessary to avoid water droplets invading the bracts, otherwise, it is very easy to cause decay. The whole plant should be sprayed because it is dry in winter. Especially when bringing flowers, the air humidity is too low, the buds are easy to fall, please pay attention.

Third, Cymbidium and Cymbidium should leave 1-2 more flowers before they bloom, and it doesn't hurt to have a little more other species. And before budding, according to the height of the flower stem, the "approach" of the three petals of the core head combines the number of leaf bundles and growth potential in the basin to remove the weak and retain the strong.

Fourth, when leaving the room, those who have flowers are still temporarily indoors, and can not be removed until after the "the Waking of Insects" festival, covering the Reed curtain every night to prevent the damage of night frost. When the spring orchid blossoms and relaxes the petals, and then move back to the indoor display, the indoor should be ventilated and transparent. If the temperature is not too low, open the air window or half-close the door at night. Where there is a fleshy bracteole flower, put it under the shade during the day and put it in a place of shelter before night, otherwise the petals are easy to wrinkle when blooming. Cymbidium cymbidium had better not be placed in the shade for the night until Qingming Festival. Close to the week before "Grain Rain", the stamens show four or five layers of bract clothing and draw arrows quickly. At this time, if there is a rainy day or long rain, you should remove the shelter from the rain and cover the curtain in time after the rain. If you are drenched or exposed to the sun for a long time, the three petals are easy to turn back, fall on the shoulder, the petals are scorched, hold the petals open, the flowers are yellowed, and the plain lips are more likely to do so. In order to avoid these shortcomings, herringbone awnings must be built to cover them up. Therefore, friends who raise orchids in the orchid room should pay attention to the fact that they can be heated and humidified before flowering, and the humidity should be adjusted to 50-60% when it is released. If the humidity of the substrate is too high, the outer three petals will grow and curl, and if there are water droplets at the end of the petals, the scape will bear weight and droop, affecting the charm of the flower posture. When cymbidium or other multi-flowered orchids are arranged in small rows, orchids without humidifiers can often spray water on the wall and ground or wet the cloth with clean water, trying every means to give a certain amount of moisture to facilitate the elongation of the stem of the flower. the petals can increase the angle and width of the petals, and the flowers are beautiful. But when opening up, it should also be managed in the same way as Chunlan, so as to get the ideal opening.
