Cultivation techniques of Dendrobium huoshanense;

1, matrix

The cultivation substrate is granite gneiss, the thickness of the stone layer is more than 20 cm, the rock is slightly acidic, and the pH value is between 5.0 and 6.5. The planting density of tissue culture seedlings should not exceed 1000 plants/m2; The planting density of ramets shall not exceed 500 plants /m2.

water

After planting Dendrobium huoshanense, it must be watered thoroughly for the first time and watered again the next day, so that the bark can fully absorb water and the surface is dry at ordinary times. It is more convenient to spray the basin surface with a sprayer, such as installing sprinkler irrigation, so that the surface of planting materials can be sprayed when it is dry. In the hot and dry season, water is often sprayed on leaves and the ground to increase air humidity. If too much water is pumped, plants will rot and die easily. In case of dry weather, timely irrigation.

3. Fertilizer

Dendrobium huoshanense is divided into organic fertilizer and inorganic fertilizer, with organic fertilizer as the main base fertilizer and pruning foliar fertilizer sprayed during the growth period. Organic fertilizers mainly include silkworm excrement, sheep manure and cake fertilizer. Inorganic fertilizers include controlled release fertilizers and water fertilizers (containing nitrogen, phosphorus and potassium, etc.). ). Water solution fertilizer was applied before and after Tomb-Sweeping Day, and then sprayed every 10 day until August. The controlled release fertilizer was applied 1 time in early April and June, and 3% trimer mineral potassium dihydrogen phosphate 1 time was sprayed every 10 day after beginning of autumn, and it was sprayed for 3-5 times.

4. Temperature

Dendrobium huoshanense began to grow at 65438 04℃. The air temperature is 20℃ to 28℃, and the air humidity is above 70%, which is most suitable for growth. When the temperature is above 32℃ and the relative temperature is below 20%, some veins turn yellow and leaves droop.

5. Light and shade method

Dendrobium huoshanense is suitable for growing in semi-cloudy and semi-sunny places, especially afraid of sun exposure. In summer and autumn, two layers of 90% shading net are needed for shading, and one layer of shading net is used in other seasons.

6, antifreeze

Artificial Dendrobium huoshanense planted in Jianghuai area needs anti-freezing in winter, especially the test-tube seedlings planted that year. In addition to building a greenhouse to prevent freezing, a layer of soil canvas should be covered on the seedbed, which is usually covered from mid-June to late February of the following year. In winter, the seedlings should not be too wet to avoid freezing the roots.
