The Culture method of Cymbidium (Cymbidium)

Chunlan, also known as grass orchid or mountain orchid, has fleshy roots and bulbous pseudo-bulbs, leaves clump and tough, about 20 to 25 centimeters long, narrow and pointed, the edge is rough. Before and after the Spring Equinox, there were flowering stems in the rhizosphere, with white membranous bracts on the stems and a flower at the tip. There are many valuable varieties with rich aroma. Cymbidium is a common original species of terrestrial orchids, mostly in temperate zones.

The cultivation of spring orchid is suitable for the end of autumn. Before planting, it is appropriate to choose a new tile basin that has been soaked in water for several hours, such as purple sand basin or plastic basin. The size of the basin is suitable for the root to stretch in the basin. Orchid mud is the most ideal culture soil, or mixed with humus (or humus) and sandy loam. Do not use alkaline soil. Before putting on the basin, Chunlan first padded tiles on the drainage holes at the bottom of the basin (preferably with 3 drainage holes), rubble, slag and other things on the pad, accounting for about 1 beat 5 of the basin, covered with a layer of coarse sand, and then put into the culture soil. It is best to put the orchid seedling into the basin, straighten the root, let it stretch naturally, gently lift the orchid seedling in the middle of the filling, and shake the flowerpot at the same time, so that the orchid root is closely combined with the pot soil, continue to fill to the edge of the basin, and press it. Leave about 3 cm along the mouth for fertilization and watering. Put the orchid in the basin and pour water into the shade. Keep it indoors in early spring and winter, and put it under the shade for the rest of the time. It is shaded from 8 a.m. to 6 p.m. In summer, and the shading degree of Chunlan should reach about 90% in summer. It is about 70% or 80% in spring and autumn.

The leaves of orchids have thicker cuticle and sunken stomata, which are more resistant to drought, so they do not need much water, so it is better to keep the orchid soil "seven minutes dry and three points wet". In general, the basin soil should be watered once every 2-3 days in spring, and the basin soil should be kept slightly dry after flowering, and it should be slightly moist after April; if the temperature is high in summer, it can be watered once a day; in autumn, it should be dry and wet; and less in winter. Spring orchid bud period, it is appropriate to keep moist, but not too wet. In the dry and hot season, spray the ground around the flowerpot in the evening to increase the humidity of the air.

Orchids do not apply thick fertilizer. It is not suitable to apply fertilizer in the first year of newly planted orchids, but can not be fertilized until the new roots grow vigorously after 1-2 years of cultivation. Generally from April to the Beginning of Autumn, fully mature thin pancake fertilizer and water are applied every 15 to 20 days. In the heat of summer, stop fertilizing. The suitable time for fertilization is in the evening. Avoid liquid fertilizer contaminating leaves when fertilizing. After the emergence of buds, Chunlan should choose a bud with the best development and the best ornamental value, and remove the rest, so as to make its flowers large and beautiful. Spring orchids can be cut off together with flowers after blooming for about 10 to 14 days, and do not wait until the natural tax falls behind to reduce nutrient consumption and facilitate flowering in the coming year.
