I. Climatic and topographical: nature of the cold, black land medicine. Library
Heilongjiang province, limkou county, is located in a cold-temperature monsoon climate of 44°-45° n, with long winters and short summers contributing to cooling, with an average annual temperature of 1. 5-3°c and extreme temperatures below 40°c. These climatic conditions, while challenging ordinary crops, provide a natural growing environment for cold chinese medicine. The terrain of the county is predominantly mountainous and hilly, with a high altitude of 300-800 metres, with a flat slope of over 60 per cent of the sunward slopes, combined with the deep black layer of corruption (8-12 per cent organic content), creating the advantage of "water drainage, soil fertility and sufficient light"。
With regard to precipitation, annual precipitation of 600-700 mm, concentrated in june-august, combined with natural irrigation systems formed by spring snow melts, meets the demand for chinese medicine and avoids the risk of water accumulation at its roots. Winter data for 2025 show that the average january temperature - 22°c, air humidity - 42% and western winds - 3-4 levels - is a "dry, cold and permeable" climate characteristic that corresponds to the springing needs of species such as ginseng, yellow and yellow。
Ii. 15 master varieties (i) roots: high value added preferred
As the leader of the northeast sanbao, lingun county has established the largest community of people in heilongjiang province. Its core planting area is located in a light slope of 600-800 metres above sea level, using the "under-forest imitation of wildness" model, with planting density within 2,000 acres per acre. Data for the year 2023 show that fresh acre production amounted to 800 kg in five years, with an acre production value of 96,000 yuan at current market prices of 120 yuan/kg. Key technologies include winter coverage of 10 centimetres of decomposed soil temperature and a 50 per cent light-exceeding sunnet in summer. Wong shui
As the first species to be certified as "three ones," the forest is known as " straight, white, pink." the area under cultivation in the county exceeded 30,000 acres and was mechanized and grown with 100 kilograms of seedling. The 2024 harvest data showed that fresh acres produced 1,200 kg, with a drying and drying rate of 3:1 and an acreage value of $18,000 per dry product of $45 per kg. The lianhua town planter li jianjiang described: "the organic content of the soil is increased by 1. 2 percentage points through rotation of purple clouds and green fertilizers, and the soap content is 0. 8 per cent, 40 per cent above the pharmacological standard. "ancesy."
In response to market demand, lingu county has focused on the development of a north acronym variety. The four-year planting cycle consists of 4,000 acre seedlings, and key management components include the pursuit of 200 kg of deer manure organic fat in spring and four artificial weeds in summer. According to the data collected in 2025, 1,500 kg of fresh acre production is valued at $45,000 at the current price of $30/kg. Experiments at county agro-technology centres have shown that membrane cover technologies can be used 15 days in advance to effectively avoid the effects of night cream. (ii) all-grass: short-term, high-efficiency piping
As a pharmacological homogeneity, linguchi county has developed a double-production model of "chip + leaves". Acreage of 0. 5 kg is grown on a lined basis, and four leaves are collected each year. Data for 2024 show that fresh acres produced 2,000 kg (average price of $8/kg), root acres produced 500 kg (average price of $15/kg) and combined acres produced 235,000. The model of "salt-breeded sprouts" promoted by the district drug associations has resulted in a 200 per cent increase in land use. Leaf grass
For the women's health market, 1,200 acres of lush grass growing base were developed in lingu county. The species is highly adaptable and can grow in soil at ph5. 8-7. 5. Mechanized harvesting results in acres producing 600 kg of hay at current prices of $12/kg and an acres at $7200. The county hospital cooperation project showed that its active ingredient, hydrochloric acid water sup base, was 1. 2 per cent above the pharmacological standard of 20 per cent. (iii) vegetables: special economic breakthroughs of five plus
As a national level ii plant protection, linguchi county develops five plus 23,000 acres through wild breeding. Its fruit is rich in thorns, with a purchase price of $80/kg in 2025. Using the 3d model "choose (red pine) + shrub (spring five plus) + grass-roots (dry) " , acre production exceeded $12,000. The county forestry service data show that the outcome period was reduced from five years to three years through indoctrination. Taste
Special emphasis is placed on the development of the north five species, with 800 acres planted using stand-up cultivation. The data from the 2024 harvest show that fresh acres produce 1,000 kg, at a current price of $25/kg and an acres at a value of $25,000. Key technologies include winter twigs wrapped in corn to protect against cold and summer application of selenium fertilizer to improve the quality of fruit. Tests have shown that it contains 0. 8 per cent of the methanol content, meeting export standards. Cost-benefit measures (in standard acres)
Note: 1. The cost of ginseng consists of five years of land transfer costs; 2. The drying rate of the yellow beryllium is required for dry goods; 3. The two-out mode of production is buming and england; 4. The jab 5 plus the cost of field care management。
Iv. Comment v. Conclusion of employment agreements: the industrial survey of the hydra
In the context of the "healthy china" strategy, the pharmaceutical industry in linguchi county is undergoing a transformation from expansion to improvement in quality. Data for 2025 show that the conversion rate of pharmaceutical products has reached 65 per cent in the county as a whole, and 12 deep-processed products, such as soap injection fluids and amphibious sugar capsules, have been developed. Through the "front enterprises + cooperatives + farmers" model, 23,000 farmers were involved in planting, with an increase of $18,000。
In the face of the future, linguchi county is working on three main systems: first, the establishment of a repository of seeded medicines, 2,000 copies of core varieties such as the depositary and the yellow dragon; second, the creation of a regional public brand of the "choose dragon medicine" with a brand value exceeding $5 billion over three years; and third, the construction of a digital traceability platform with full chain control from planting to marketing. As the county director of agriculture and rural affairs said, "we're going to make every potion an ecological business card in the cold, black land, and we're going to fill the country's path of renewal."
