How to keep potted orchids fragrance
Experienced flower growers all know that potted wild orchids, over time, their rich aromas will fade year after year, because the growth environment of potted orchids has changed compared to wild orchids. . Under potted conditions, if they are adapted artificially to meet the optimal environmental conditions of orchids as much as possible, they can maintain their original fragrance.
First, a reasonable choice of pots and pots and soil. It is better to use a mud pot for domestic orchids. This is because the aeration of the mud pots is better than that of the glaze pots, the water seepage is fast, and the pot soils are dried fast. The orchids do not cause rot roots due to a long time of excessive humidity. robust. Wild orchids grow in long-term soils with high humus content. The organic humus content of such soils generally accounts for more than 80%. However, the content of humus in potted earth orchids grown in general is only about 40%, which is unfavorable for strong plants, pregnant buds and flowering of orchids. Therefore, when selecting and producing potted soil, domestic orchids should use 3 parts of edible fungus residue, 3 parts of dried cow dung, 2 parts of chicken and duck dry manure, 2 parts of sandy garden soil, mix and pile up, and mature. Soil organic humic substances content is generally more than 80%, fertile loose, moisturizing ventilation, suitable for orchid growth, favorable bud, flowering and maintain the strong aroma of orchids.
Second, increase phosphorus and potassium fertilizers. Phosphorus and potassium fertilizers are important elements for long roots, health, buds, and aromatic honey. Therefore, during the growing period of orchids, it is necessary to pay attention to the use of decomposed bean cake water and sauce water to be poured once every half month. In winter and spring seasons, it is often used to apply some ash to orchids. In spring, summer and autumn, it is sprayed 1-2 times per month. % of potassium dihydrogen phosphate, so that the blue plant growth is robust, thick green leaves, strong resistance, accumulation of nutrients, make aromatic honey, good for restoring and maintaining the aroma of orchids have a significant effect.
Third, avoid basin soil too dry and wet. Although in the winter, orchids should greatly reduce the amount of water, they must not be poured and should not be allowed to be fully dried and then poured. If the basin soil is too dry in the winter, the pseudobulbs of the orchids are prone to cause dryness, and other tissues will affect metabolism due to excessive water loss, resulting in poor plant growth, resulting in leaf blight and even death. If the basin soil is too wet, then its poor ventilation will easily lead to rot and poor growth of the plant, and the flowers will lose their scent.
Fourth, increase the temperature. The winter horticultural orchids, magnolias and chrysanthemums are often attacked by frost and cold winds. The temperature is too low, and the aromatic honeydew will close on its own, stopping the aromatic odor. In order to keep the potted orchids growing robustly and safely overwinter, in the cold season, doors and windows should be closed, and the indoor temperature should be maintained at about 10° C. during the day and at least not less than 5° C. during the night to meet the temperature required by the aroma.
