Cultivation technology for promoting tuber of traditional Chinese medicine bletilla striata to expand

Abstract

The invention relates to a cultivation technology for promoting a tuber of a traditional Chinese medicine bletilla striata to expand, comprising the following steps of: (1) selecting subacid to neutral sandy loam with a pH value of 4.8-6.9; (2) compartmenting and ridging in south and north directions; (3) adopting planting distances and row spacings which are specified on each compartment as carrier density; (4) enabling a growing point of the seed stem of the bletilla striata to be upward and form an angle of 35-80 degrees with covering soil; (5) sufficiently applying special base fertilizers into a cavity with the depth of 15-20cm to cover soil, and planting the seed stem of the bletilla striata into the cavity and then covering the soil with the thickness of 2-3cm; (6) shading the bletilla striata through intercropping shading crops; and (7) applying special bletilla striata fertilizers as base fertilizers and additional fertilizers. The invention can increase the acre yield of the planted bletilla striata by 250 percent and the output value thereof by 310 percent by adopting the scheme compared with the traditional planting way and has good economic and social benefits.

Description

Technical field [0001] The invention relates to a technique for artificial cultivation and domestication of wild Chinese medicine to increase its economic output, in particular to a cultivation technique for promoting tuber enlargement of the Chinese medicine Bletilla striata. Background technique [0002] The dried tubers of Bletilla striata are traditional Chinese medicinal materials that come from wild resources. With the increase in the amount of medicine used, wild Bletilla striata resources have decreased sharply. In addition, people have over-excavated and slightly robbed the wild Bletilla striata. Bletilla striata is grown from wild to artificial domestication. Using conventional cultivation techniques, Bletilla striata is often grown. The above-ground plants of Bletilla striata grow luxuriantly and grow strongly. However, the tubers that grow underground, which are used as medicine, grow poorly. Tuber enlargement is difficult, which makes artificially planting Bletilla s...

Problems solved by technology

[0002] The dry tubers of Bletilla striata are traditional Chinese medicinal materials, most of which come from wild resources. With the increase of dosage, the resources of wild Bletilla striata have decreased sharply. Bletilla striata is changed from wild to artificially domesticated and cultivated, and conventional cultivation techniques are used to plant Bletilla striata. The aboveground plants of Bletilla striata often grow luxuriantly and grow very strong, but the underground tubers that are used as medicine grow very p
