The invention discloses a planting method of
selenium-enriched
anoectochilus roxburghii hayata. The method includes the steps that
straw,
saw dust, tea cakes and sheep dung in
selenium-enriched areas are collected, separately smashed and then mixed, water is sprayed in an evenly mixing process, and obtained mixture is stacked into a stack; 10-15 days after stack
retting, the stack is turned over for the first time, and
moisture is supplemented;
moisture is preserved, and stacking is conducted again; then,
every five days, the stack is turned over,
moisture is supplemented and the stacking is conducted again;
fermentation is conducted till substrate turns to black brown, when the temperature falls to a near ambient temperature,
humus soil (with natural orchid
mycorrhizal fungi) collected in a growth place of wild
anoectochilus roxburghii hayata is added and evenly stirred in the substrate, and planting substrate is obtained;
greenhouse cultivation or under-forest imitative wild planting is conducted on tissue culturing seedlings of the
anoectochilus roxburghii hayata by the adoption of draught-fan water-curtain equipment; clear water is sprayed according to the
humidity of the substrate, and ventilation and
light penetration are ensured; biological prevention and control on
plant diseases and
insect pests are conducted; harvest is carried out. The obtained
anoectochilus roxburghii hayata has relatively good agronomic trait indexes, the biological yield is improved, and the content of flavone, the content of active
polysaccharide and the content of
selenium are significantly increased. The materials of the substrate turn waste into wealth, the
pollution is reduced, and the cost is greatly reduced.
