Orchids-- three essentials of cold orchid cultivation

People have a saying about the cultivation of Han orchid as "narrowly missed death". In fact, as long as we master the essentials, the reproduction rate is not lower than that of Chun and Huilan. I have been down the mountain for more than three years and its seedling emergence rate is more than 50%. Now I would like to introduce some experience in the process of cultivation to Lanyou.

I. planting

Cold orchid grows under the dense broad-leaved forest on steep slopes with little light, shallow roots, covered with a thin layer of humic soil and good water permeability. Therefore, when planting, the purple sand basin with high feet is selected, the bottom of the basin 1/3 is filled with coarse-grained bricks and Styrofoam, and the middle is mixed to basin 1/3 with mushroom mud, coarse sawdust, wind fossils, phytolith, pond cornerstones and soybean-sized bricks. The upper part is mixed with rice-sized wind fossils and bricks and a small amount of humus soil. Planting requires loose, breathable, water-efficient and strong thermal insulation. In particular, attention should be paid to the cultivation of hard plants, sawdust, humus soil and so on, the survival rate, seedling rate and flowering rate are not high.

II. Cultivation

Because the growth environment of cold orchid is different from that of spring and cymbidium, the cultivation method should be slightly different. First, the shade and temperature are similar to those of Mulan. Especially in the hot season with strong light, we should pay more attention to shading and moisturizing. In addition, foliar water should be sprayed in the morning or evening on a sunny day, with a shade of about 80%. In this way, the leaves are shiny and the disease is less; in the high temperature season, I put the cold orchid on the lower layer of the orchid frame, on which there are spring orchids and cymbidium to block the light, and the effect is quite good. Second, anti-wind and anti-freezing. In autumn and winter, avoid strong winds and keep warm on frost days. The third is fertilization. The cold orchid planted according to the above-mentioned plant materials can generally apply less or no fertilizer, and chemical fertilizers with high nitrogen content, such as Huabao 4, B1 and so on, can be sprayed on the leaves from April to June. Chemical fertilizers containing phosphorus and potassium were sprayed from August to October, such as flowering fertilizer, Huabao No. 3, potassium dihydrogen phosphate and so on.

III. Maintenance

Whether the cold orchid can blossom, blossom well, float faint fragrance, maintenance is very important. If the dark flowers, the light should be slightly stronger, the light of the vegetarian heart should be a little shader. Flower arrows begin to grow to before flowering, if you do not pay attention to plant protection, the flower bracts are easy to rot. For this reason, the bud of cold orchid is also easy to be stung by mites, and the color of the pest is similar to that of the bud, which is often not easy to find, and must be prevented and controlled in time, otherwise the flowers will not bloom. Therefore, it can be effectively prevented by spraying insecticides such as Huakang No.1 and permethrin. Cold orchid blooms mostly in late autumn and early winter, and the weather is getting colder and colder. In order to make cold orchid fragrance elegant, the flower exhibition period should bask in the sun more often, even if it is only fragrant at night. Cold orchid fragrance beautiful, colorful, scape high above the shelf, Ye Ting bow, dense, elegant floating, soft with rigid, leaves and flowers are elegant, in China Orchid, its unique charm and will be valued.
