Introduction to Tang Banxia

Tang Banxia is a specialty of Tanghe County, Henan Province, and a national geographical indication product of China.

. The Pinellia ternata grown in Tanghe County is a broad-leaved dry Pinellia ternata. Due to the mild climate and moderate rainfall, wild Pinellia ternata can be found everywhere. The people here have had the traditional habit of digging and processing "medicinal dog eggs" into medicinal herbs for sale since ancient times to subsidize their families. There is a common saying in rural areas of Tanghe: "Eating salt depends on three eggs, eggs, duck eggs, medicine, dog eggs", which shows the traditional position and historical origin of Banxia in the economic life of the masses. Due to its large size, excellent quality, and significant medicinal effects, Pinellia ternata has been praised as "Tang Pinellia ternata" by renowned traditional Chinese medicine practitioners, pharmacists, and merchants throughout history

Tang Banxia is suitable for moist and shady environments below an altitude of 2500 meters, with loose loam or sandy loam being the best, and the soil pH value should be within the range of 6-7; The most essential nutrients are nitrogen, phosphorus, and potassium, with potassium being the most important. When potassium is deficient, the tubers and bulbous buds swell slowly and appear as long columns; Likes humid environments and is not tolerant to drought; Prefers warmth and weak light, but fears strong light. The most suitable temperature for tuber and bead bud expansion is between 18 ℃ and 20 ℃. Usually, seedlings begin to emerge in early March of the lunar calendar when the temperature exceeds 13 ℃, begin to fall in early June when the temperature exceeds 30 ℃, re emerge in July and August when the climate slightly cools down, and fall again in September and October when the temperature drops below 15 ℃; The period from 15 ℃ to 26 ℃ is the fastest for the growth of stems and leaves, as well as the expansion of root tubers in Pinellia ternata. The suitable growth environment can be summarized as follows: shaded soil, moist and fertile soil, moisture content of 20% -30%, pH value of 6-7, with sandy loam and yellow brown soil being the best

Production situation

According to the sales statistics of Pinellia ternata in Nanyang from 1957 to 1983, the highest annual purchase of Pinellia ternata in Nanyang was 100000 kilograms, with an average annual purchase of 61049.5 kilograms and a sales volume of 28688 kilograms. The wild reserves were 632518 kilograms

Tang Banxia resources have suffered serious damage. In 1983, the purchase volume of Pinellia ternata was only 310 kilograms, while the sales volume in the same year was 1030 kilograms, a difference of 720 kilograms. The main reason for this was that the expansion of machine cultivation area destroyed the reproduction of Pinellia ternata buds, greatly reducing their regeneration ability; Secondly, due to intensive cultivation, wild resources have been depleted

Quality and technical requirements

(1) Species name

Pinellia ternata

(II) Cultivation Techniques

1. Growth Environment: Wild or semi wild environment, altitude of 80 to 200 meters, sand ginger black soil and yellow brown loam soil, deep soil layer, fertile soil, pH value of 6.5 to 7.5, soil organic matter content of 0.69% to 1.49%

2. Seed collection: The cultivated seeds of Tang Pinellia ternata must be collected from wild species within the protection range of geographical indication products and good varieties produced by breeding bases, and no other varieties shall be introduced. In June and October, harvest tubers and pearl buds, remove impurities from the soil, and let them dry for later use. Or harvest berry seeds, sun dry and store for later use

3. Seed selection and sowing:

Pearl bud seeds: diameter of 0.3 cm to 1 cm, sowing rate of 20 kg to 35 kg per mu. The spacing between plants is 3 × 15 centimeters, and the sowing depth is 3 centimeters. Two year harvest

Tuber species: diameter of 0.7 cm to 2 cm, sowing rate of 40 kg to 65 kg per mu. The spacing between plants is 3 × 20 centimeters, and the sowing depth is 4 to 5 centimeters. One year harvest

Pearl bud seeds and tuber seeds are soaked before sowing to promote germination. Soak the seeds for 1 hour, remove them and place them on a hot bed (22 ℃ to 24 ℃) with a spacing of 40 cm to 50 cm per square meter. Cover with grass to keep them moist, and sow when the sheaths turn white

Berry seeds: Soak the seeds in warm water at 20 ℃ for 1 hour, place them on a hot bed (15 ℃ to 25 ℃) to promote germination until the seeds are white, and then sow. Sow in sunny beds, with a bed width of 1.35 meters. The row spacing is 15 centimeters, and the sowing rate per mu is 0.5 centimeters. Three years of harvest

(III) Harvesting and Processing

1. Harvesting: The mature harvesting period of Pinellia ternata is in mid to late June and mid to late October. Harvesting method: use a shovel to dig along the planting ridge, with a depth of 10cm. Pick up tubers with a diameter of more than 1 centimeter for processing medicinal materials. Small stems and buds can be detected and stored for planting, or left in the digging ditch to avoid replanting in the next season

2. Processing: Put the harvested tubers into a container, wash away the soil with water, put them in a woven bag, and place them on a stone slab dipped in water and vigorously pushed and rubbed. When more than 90% of the peeled tubers are white, pick out the non peeled tubers, float the peeled residue, and place them on a mat for sun exposure or drying on a heated kang

(IV) Quality Features

1. Sensory Features: The appearance is spherical or semi-circular, with a diameter of 0.8 cm to 2 cm, a white surface, a stem scar pit in the center, and densely covered with fibrous root scar pits around it. The bottom is dull, round, and smooth. The texture is solid, dense, kidney shaped in longitudinal section, pure white, with a pungent powder smell, spicy taste, sticky when chewed, numb tongue and prickly throat. Large, clean skin, white color, firm texture, and sufficient powder

2. Physical and chemical indicators: moisture content ≤ 14%, pesticide residue below the national GAP standard for traditional Chinese medicine
