The main points before orchid conservation

(1) pay attention to adjusting the dry and humidity matrix of the tomb, if it is too dry, the development of the flower will stagnate, or even wilt, and the bud will fall; if it is too humid, it is prone to water stains and rotten roots, so that the development of the flower will lose its supply line and either cannot open smoothly or shorten the flowering period.

(2) pay attention to regulating the temperature of orchid flower bud differentiation and development, requiring a temperature of more than 12-13 ℃. If the flower bud is too low to develop slowly, it is difficult to open; even if it can open slowly, the aroma of the orchid paste is not easy to volatilize, so the aroma is less or less fragrant. If the temperature is below zero degrees Celsius, the flowers will be frozen and rotted; if the temperature is higher than 32 ℃, the flowers will not develop normally and are prone to wilting and early withering due to muggy heat. The flower buds of Cymbidium need to have a low temperature vernalization stage with a temperature below 10 ℃ and above 3 ℃ for 15-22 days, and then transferred to the environment of 12-13 ℃ or more in order to bloom normally. Therefore, attention should be paid to the regulation of temperature during flowering to make it within the best range.

(3) pay attention to adjusting the amount of light during the flowering period of orchids, if there is too little light, there will be dark colors, poor appearance, and insufficient aroma; if the light is stronger, the orchids will be bright, exuberant and rich in aroma. But it is also not resistant to direct bright light, but should be open in a normal sunshade environment. This requires that when the light is strong in summer and autumn, there should be normal shading conditions to ensure the orchid blooming; although the light in winter and spring is weak, but the light is also strong around noon, it should also be shaded properly.

(4) thinning of flower buds for potted orchids and cluster orchids with too many and too dense flowers, they should be removed as soon as possible; for traditional and stable varieties that do not need to blossom, their flowers should also be removed as soon as possible; for those with too many buds, they can also be retained and shrunk and properly thinned. In this way, the consumption of the plant can be reduced, which can not only make the flowers open in that year are large, colorful and fragrant, but also conducive to the growth of the orchid plant and the germination and flowering of the following year.
