Ningqiang’s Wild-Simulated Gastrodia elata Herb Planting Bases

Located in the Qinba Mountain ecological corridor, Ningqiang County of Hanzhong City, Shaanxi Province, relies on abundant forest resources and superior mountain microclimate to build large-scale wild simulated herb planting bases dominated by black Gastrodia elata. Breaking the mode of open-field intensive cultivation, Ningqiang simulates the wild growth environment of wild gastrodia under natural forests, realizes pollution-free ecological cultivation of medicinal materials, combines forest protection with Chinese herbal medicine planting, and forms a sustainable forest-medicine integration development model. It has become a typical demonstration area for wild simulated planting of authentic gastrodia elata in northwest China.

Unique Forest Ecology, Natural Foundation for Wild Simulated Planting

Ningqiang boasts a forest coverage rate close to 80%, with vast oak, poplar and miscellaneous broad-leaved forests across mountain areas. The mountain forest forms natural shading, stable humidity, scattered scattered light and thick humus layer rich in organic matter and beneficial microorganisms, which completely reproduces the primitive living environment of wild gastrodia elata in deep mountains.

The area belongs to the transition zone of subtropical and temperate climates, with mild temperature, dispersed rainfall and proper ventilation under the forest. There is no need for manual sunshade, watering and frequent fertilization during gastrodia growth. Relying on fallen leaves, rotten branches and natural soil fertility in the forest, gastrodia tubers grow slowly and compactly, accumulate abundant gastrodin and active medicinal components, and the medicinal quality is close to wild gastrodia. Such superior ecological conditions make Ningqiang naturally suitable for building high-quality wild simulated herb planting bases.

Core Mode of Wild Simulated Under-Forest Gastrodia Cultivation

All wild simulated herb planting bases in Ningqiang follow the principle of “adapting to nature, minimal intervention, forest conservation first”, and formulate unified technical specifications matched with wild simulation standards:

1. Site selection under natural forests Select hillside broad-leaved forest land with shade rate kept at 70%–85%, loose humus soil and good drainage, avoid felling large trees, only properly trim redundant branches to adjust light transmittance, protect the original forest ecosystem intact, and realize coexistence of trees and medicinal herbs.
2. Natural strain matching cultivation Deploy domesticated high-quality gastrodia seeds and Armillaria mellea strains adapted to local forest soil, bury fungus sticks and seeds in shallow soil layers under the forest. No chemical fertilizers, chemical pesticides, herbicides are applied in the whole growth cycle; natural forest insects, soil microorganisms form ecological balance to prevent diseases and insect pests, realizing pure green planting.
3. Wild growth cycle management Consistent with the growth rhythm of wild gastrodia, extend the growth cycle appropriately. Workers only carry out regular drainage inspection, weeding and simple protection work in the base, reduce human disturbance to the greatest extent, let gastrodia absorb natural nutrients in the forest environment naturally, guarantee the medicinal property and taste of Ningqiang black gastrodia.
4. Rotational fallow planting mechanism After harvesting gastrodia in one forest plot, implement 2–3 years of fallow protection, restore soil fertility under the forest, prevent continuous cropping degradation, avoid excessive development damaging forest vegetation, solve the ecological hidden danger of traditional gastrodia planting consuming a large amount of wood, and achieve the circular development of protecting forests while planting medicinal herbs.

Standard Construction & Quality Certification of Wild Simulated Planting Bases

Ningqiang incorporates all under-forest wild simulated gastrodia parks into standardized management of medicinal herb bases, docking GAP medicinal material management system, and obtains multiple authoritative certifications to endorse the quality of wild-simulated gastrodia:

1. All core wild simulated herb planting demonstration zones are included in the provincial GAP Chinese medicinal herb base management system, implement whole-process record keeping of site selection, sowing, daily management and harvesting, and build a medicinal material traceability system.
2. Ningqiang Gastrodia elata owns national geographical indication trademark certification and ecological origin product certification. Test data shows that the gastrodin content of gastrodia produced by wild simulated under-forest planting is significantly higher than that of greenhouse potted gastrodia, meeting the medicinal raw material standards of pharmaceutical enterprises.
3. Several wild simulated planting plots have passed organic agricultural product certification, and their gastrodia products are supplied to pharmaceutical factories, health product enterprises and high-end medicinal material markets at home and abroad as high-quality wild-grade medicinal materials.

Industrial Scale & Ecological and Economic Benefits

At present, the area of under-forest wild simulated gastrodia planting in Ningqiang County has reached more than 38,000 mu, accounting for over 60% of the county’s total gastrodia planting area, distributed in mountain villages of all towns. Relying on wild simulated herb planting bases, the local industry adopts the operation model of “cooperative + forest land farmers + base”, uniformly providing improved seeds and technical guidance for mountain farmers, and recycling fresh gastrodia uniformly after maturity.

Ecological benefits

Wild simulated planting does not destroy forest vegetation, effectively makes use of idle under-forest space, increases ground coverage of forest land, reduces mountain soil erosion, realizes the dual goal of protecting forest ecology and developing medicinal herb economy.

Economic benefits

Under-forest wild gastrodia has higher market pricing power due to excellent quality. The wild simulated gastrodia industry drives more than 20,000 mountain households to engage in forest-medicine planting, greatly increasing the income of villagers living in forest areas. Meanwhile, the base also drives supporting industries such as strain cultivation, primary processing of gastrodia and medicinal material logistics, becoming an important characteristic industry for local mountain rural revitalization.

Development Prospect of Wild Simulated Herb Planting Base

In the next stage, Ningqiang will continue to expand the scale of standardized wild simulated gastrodia planting bases, build intelligent monitoring points in forest medicinal fields to monitor temperature, humidity and soil conditions under forests in real time, optimize wild simulated cultivation technologies, and launch standardized wild-simulated gastrodia specialty series.

Taking wild simulated under-forest planting as the core characteristic, Ningqiang will further highlight the ecological advantages of authentic gastrodia origin, take the wild simulated herb planting base as a carrier, polish the brand of Qinba daodi gastrodia, and set a replicable popularization model for the green development of under-forest Chinese medicinal herbs nationwide.
