What are the points for attention in planting Anoectochilus roxburghii?

1. Scientific selection of land

In artificial cultivation of Anoectochilus roxburghii, the planting site should be located in the shady place beside the stream gully in the woodland with high altitude, which is the key to the success of cultivation, which is required to be above 400m above sea level, near the mixed zone of broad-leaved forest or coniferous broad-leaved forest. It is required that the average temperature in January is 10 degrees Celsius, the average temperature in July is 25 degrees Celsius, the air relative humidity is 70%, the wind is light or calm, the transmittance is about 30%, there are water sources around, and the soil structure is good, preferably neutral or slightly acidic (pH=4.5~6.5) weathered yellow loam.

2. Scientific planting

The planting of Anoectochilus roxburghii should be shallow rather than deep. After planting, it is best to cover clean and dry moss, and the row spacing is 5~10cm*5~10cm. Immediately after planting, the root water should be poured to ensure the survival rate. The higher altitude mountain area should be planted from April to May in spring, which can accelerate the growth and harvest in the same year. The low hills on the flat land should be planted from August to September in autumn, which can avoid the high temperature in summer and the peak period of the spread of diseases and insect pests, and increase the survival rate and yield.

3. Field management

The field management of Anoectochilus roxburghii is directly related to its survival rate, growth and yield. The growth cycle of Anoectochilus roxburghii requires less light and heat, especially the strong direct light around noon, so a shading shed should be set up on the cultivated ground to adjust the light transmittance. Anoectochilus roxburghii needs water, but it is not suitable for stagnant water, so the amount of water should depend on the development of seedlings and the environment in which they grow. After planting Anoectochilus roxburghii, the main types of fertilization should be slow-acting organic fertilizer, such as soybean cake after fermentation diluent, pig manure, cow and horse manure and other farm manure, if you can cooperate with spraying foliar fertilizer is better, usually add a small amount of ferrous sulfate per 100kg fertilizer solution, in order to promote the leaf color thick green and rich luster.

Do not pollute the leaves of Anoectochilus roxburghii when fertilizing. if you inadvertently do so, you should spray clean water immediately. The harmful factors and the occurrence of diseases and insect pests are mostly caused by high temperature, poor ventilation, light and unclean cultivation land. Therefore, efforts should be made to overcome these adverse factors and remove weeds.

4. Harvest

Anoectochilus roxburghii can be harvested 4-5 months after planting, with a plant height of more than 10cm, 6 leaves and a fresh weight of 1-2g. When harvesting, pull up the roots (you can also cut the stem and leave the roots for regeneration), shake off the soil, expose it to the sun or dry it with fire to become dry products.
