The cultivation of Zhongjiang white pheasant originated from the Qing Emperor Qianlong period and was first published in the 1812 AD of Zhongjiang County (Jiaqing Edition). In the second year of Qing Xuantong, the output of medicinal materials in the county was 25,504 years old. In 1912, the annual production of dried glutinous rice was more than 100 tons. In 1926, 1000 acres of white carp were planted, with a total output of nearly 200 tons, which was exported to foreign countries. In 1933, 1133 acres were planted. The total output is more than 400 tons, the output is 250kg per mu, and the export is more than 150 tons. In 1949, 247 acres were planted, with a total output of 52.75 tons and a yield of 214kg per mu. In the summer of 1956, three experts from the Soviet Union, the Democratic Germany, and the Bulgarian plant visited the village of Zhongqing, and examined the production of white peony. In 1959, the original Shiqian Commune established the Baiji Production Team, also known as the “White Pelican Farm”. In 1977, 1472 mu was planted. It produces 804.8 tons and yields 547kg per mu.

Zhongjiang white carp quality technical requirements First, the original plant Paeonia Lactiflora Pall. 2. Site conditions: The average temperature is 400°C to 900m, the annual average temperature is about 16°C, the annual precipitation is about 880mm, the annual sunshine hours are about 1200 hours, and the annual frost-free period is ≥290 days. The soil is dominated by sandy loam and the thickness of cultivated layer is ≥ 30 cm, organic matter content ≥ 1.4%, pH 7.0 to 8.0. Third, cultivation techniques Breeding method: When harvesting the root of peony in autumn, choose the thick hoe (no red bud head) without pests and diseases, no mold, no hollow, no shrinkage as the propagation material, according to the size, number and natural growth shape of the bud. Cut into pieces, each piece needs to have 2 to 3 thick bud heads, and about 3 cm left under the axillary buds. 2. 3. Fertilizer and water management: In the year of planting, apply organic fertilizer per 667m2 (mu) of more than 1000kg, and apply more than 1500kg of manure per year. 4.

Select the sunny day, first cut off the stems and leaves, dig all the roots, pick the net and shake off the soil, cut the roots from the hoe, then cut the lateral roots on the thick roots, smooth the convex surface, cut the head The tail is divided into three files according to the big, medium and small. It is piled up indoors for 2 to 3 days, and it is turned up twice a day to promote evaporation of water from the roots, and the texture becomes soft and easy to process. 2. Processing: (1) Cooked clams: 1 Boiled clams: According to the thickness of the clams, they are boiled in boiling water to boil them. The amount of water is suitable for submerging the roots. 2 Peeling: Quickly remove the cooked roots from the pot and immediately immerse them in cold water to make them unevenly heated inside and outside, which is convenient for peeling. 3 Carefully scrape the outer cork of the root of the root with a bamboo knife and dig the wormhole. Disable the iron cutter to scrape the skin, otherwise the root will be discolored and then aired. 4 Drying: The cooked roots are transported in time to the drying field, and the skin is spread thinly. The first exposure is 1 to 2 hours, and the thickness of the roots is gradually expelled to make the skin shrink slowly, and the water content is ≤13%. (2) Oyster: The processing of raw white peony is mainly natural drying. In the process of drying and drying in the process of drying, in order to prevent moldy roots, you can use the simmer to bake the roots for 1 to 2 hours every day. V. Quality characteristics 1.
