Planting technique of Dendrobium candidum

Selection and preparation of soil: Dendrobium purpureum is suitable to grow in the environment of light, temperature and humidity balance, the temperature in winter should not be lower than 0℃, and the soil should be tilled and disinfected. Plant division propagation: mainly plant division propagation, can be planted around February 4 in early spring, select high-quality disease-free stem seeds, cut off old stems, dressed with farm manure and put into planting holes. Later management: ensure soil moisture, water with small drop irrigation or sprinkler irrigation, timely topdressing, and do a good job in disease prevention and control.

1. Land selection and preparation

1. When selecting planting plots, it should be decided according to the conditions required for the growth of Dendrobium purpureum. Dendrobium purpureum likes to grow in an environment with balanced light, temperature and humidity, and the temperature in winter should not be lower than 0℃ during this period.

2. Of course, the planting environment can also be artificially regulated, as long as it is ensured that Dendrobium purpureum is in a suitable growth environment. When planting, tall trees such as pear trees are needed around to shade Dendrobium purpureum, and then the soil is tilled and disinfected, which is conducive to reducing the bacteria in the soil, thus reducing the incidence of Dendrobium purpureum.

II. Plant division propagation

1. The propagation method of Dendrobium purpureum is generally based on division propagation, and the time can be selected to be planted around February 4 in early spring, because the rain in spring is sufficient, which is conducive to promoting the growth and development of Dendrobium purpureum, and its planting survival rate will be relatively high.

2. Then select high-quality, disease-free stem seeds of Dendrobium purpureum, cut off the old stems, plant them with new stems, ensure that the stem seeds are robust before propagation, and disinfect them, and then put them into planting holes after dressing them with farm manure.

III. Post-management

1. Management should be done well after successful planting. The late management of Dendrobium purpureum is very critical. Improper management will cause abnormal growth of Dendrobium purpureum. During the whole growth process of Dendrobium purpureum, the soil should be kept moist, but the air humidity should not be too high.

2. When watering, small drop irrigation can be used, or sprinkler irrigation can be used, and topdressing shall be carried out according to soil fertility and growth of Dendrobium purpureum to ensure sufficient nutrition during growth period. In the later stage, pruning shall be carried out properly according to the growth of tree shape and branches, which is conducive to improving permeability in the field and promoting healthy growth of Dendrobium purpureum.

IV. Prevention and control of diseases

Dendrobium purpureum has the possibility of disease in all growth stages, and there are many kinds of diseases, which will also cause different degrees of harm to Dendrobium purpureum. Therefore, during the growth period of Dendrobium purpureum, field management should be strengthened, sick and disabled bodies should be removed in time, and field disinfection should be carried out regularly, which is conducive to reducing the number of field germs, reducing the incidence rate and preventing unnecessary losses.
