Cultivation techniques substrate cultivation substrate for granite gneiss, the thickness of the stone layer is greater than 20 centimeters, the rock is slightly acidic, pH value between 5.0 and 6.5.

The planting density of group cultivated seedlings is not more than 1000 plants/square meter; the planting density of split plants is not more than 500 plants/square meter. Watering Huoshan Dendrobium planted after the first watering must be watered through, the next day but also re-watering once, so that the bark to eat through the moisture, usually the surface is dry, with a sprayer to spray wet pots, such as the installation of sprinkler irrigation is more convenient, the surface of the planting material can be sprayed when dry. In the hot and dry season, often spray water to the foliage and ground to increase air humidity. If there is too much water, draw water, the plant is easy to rot and die. In case of dry weather, timely irrigation.

Fertilizer

Huoshan Dendrobium fertilization is divided into organic fertilizer and inorganic fertilizer, organic fertilizer as the main base fertilizer, with the foliar fertilizer sprayed during the growth period, organic fertilizer is mainly sericultural dung, sheep dung, cake fertilizer, etc.; inorganic fertilizer has controlled release fertilizer and water solution fertilizer (containing nitrogen, phosphorus and potassium components, etc.). Water solution fertilizer first applied before and after the Qingming, and then sprayed every 10 days until August; controlled-release fertilizer in early April and June, once each, every 10 days after the autumn spray "Zephyr" potassium phosphate, *** spray 3 to 5 times.

Temperature

Dendrobium huoshan temperature at 14 ℃ to start growing; temperature of 20 ℃ to 28 ℃, air humidity in more than 70% of the most suitable for the growth; temperature above 32 ℃, the relative temperature of less than 20%, part of the leaf veins turn yellow, leaf drooping.

Shade

Huoshan Dendrobium is suitable to grow in semi-shade and half-sun place, especially afraid of exposure to the sun, summer and fall need to use two layers of 90% of the shade net shade, the other seasons are using a layer of shade net. Anti-freezing artificial cultivation of Dendrobium huoshan in the jianghuai region in the winter need to be anti-freezing, especially when planted test tube seedlings, in addition to building greenhouses to prevent freezing, but also cover a layer of soil canvas cover the seedling bed, generally in mid-December to cover the next year in late February. Seedlings can not be too wet in winter to prevent freezing and damage to the root system.
