"Orange tree sandbar is dark, pineapple wine is spring." Since ancient times, people have a soft spot for pine nuts and nuts. The appearance of Wuying Hongsong seeds is dark reddish brown, the skin is smooth, shiny, with large particles and full of seeds. Korean pine nuts are rich in protein, carbohydrates, vitamins A and vitamin E, as well as essential fatty acids, oleic acid, linoleic acid and linolenic acid, as well as pinolinoic acid not found in other plants. It has the effect of prolonging life and strengthening the body. Red pine seed is a wild medicine and fruit with high economic value.

Geographical environment The hometown of Hongsong is located in the north of Yichun City, Heilongjiang Province, and the south slope of Xiaoxing'anling. According to people who used to hunt, pick up mountains and logger in the mountains, they called the temporary shelters and residences away from the crowds as “battalions”. Such as the dumplings camp, the head camp and so on. The Fifth Battalion is a place for hunters and ethnic minorities to hunt and pick up mountains. It is named after five camps along the ditch. The mountains here are densely forested and inaccessible, and the original state of the big forest is still maintained. The Korean pine needle broad-leaved mixed forest constitutes the top plant community in the Xiaoxing'anling primeval forest. Pinus koraiensis is highly phototropic and has high requirements for soil moisture. It should not be used in dry and over-humid soils and in cold weather. It grows best on warm, rainy, relatively high humidity climates and deep, fertile, well-drained acid brown forest soils. Pinus koraiensis semi-positive tree species, shallow roots, often born on well-drained wet soil slopes, saplings resistant to shade, sensitive to atmospheric humidity. The Wuying genus is a mid-temperate continental humid monsoon climate with cool temperatures and abundant rainfall; the forest is dominated by dark brown soil, the soil is fertile, and the organic matter content is high; plus biodiversity and intact biomes constitute the most growth of Korean pine. Good environment. Natural Korean pine forests are mainly distributed in parts of China, Russia, North Korea and Japan. At the beginning of the 20th century, the distribution area of ​​natural Korean pine forests reached 50 million hectares. Among them, China has 30 million hectares, accounting for 60%, and is concentrated in the Xiaoxing'anling (Yichun) mountain and Changbai Mountain. Red pine seed is the seed of wild Korean pine. The cold climate causes the growth of Korean pine to be slow. The wild Korean pine is 80 to 140 years old, which also creates the unique quality of Korean pine seed. The red pine seed has a large harvest in 5 years, and a small harvest in 3 years. 50% of the domestic red pine seed production comes from the Wuying. Red pine is the city tree of Yichun. It is often said that if you haven’t been to the five camps, you have seen the red pines and you have never been to Yichun. The five camps are veritable “hometown of Hongsong”. Cultural background The legend of Korean pine is said to be a couple of lovers living on the banks of the Tangwang River. The name of the man is Dashan and the name of the woman is Lin Mei. One day, Lin Mei went to the mountains to pick mushrooms, strayed into the territory of the monster, and was taken away by the two monsters in the mountains. Dashan heard the news, grabbed the hunting knife and rushed to the mountains, and chased for three days and three nights and did not find Lin Mei. At this time, the mountain was already tired and could not walk, and with the sad mood, almost passed out. At this time, a sika deer came out of the woods in the distance. It came to the front of the mountain and said to him: "Brave people, eat these grasses, I will take you to save the forest girl." Eat the grass, and feel the spirit is a hundred times, full of strength. The sika deer disappeared before the mountain came to a stone forest. Dashan saw that Lin Mei was tied to the stone pillar and immediately ran forward. When she was about to be rescued, the second stranger heard the news and smashed it with Dashan. In the end, the second blame was killed, and the mountain also ran out of the last drop of blood, standing and dying. In the spring of the next year, the place where Dashan died was a tall, blood-red tree with a cluster of azaleas. The love story of Dashan and Linmei touched the mountain god, and all the flowers and trees in the mountain were dressed in festive costumes, blessing the lovers. This is the beautiful golden autumn "Wuhua Mountain" in Xiaoxing'anling. This magical land is the hometown of Hongsong - Yichun. Brand building protects the action of Korean pine - winter to spring. Red pine is the symbol of Yichun. At the beginning of the development of Yichunlin District, the natural Korean pine forest covers an area of ​​about 1.08 million hectares and accumulates about 150 million cubic meters. After long-term excessive harvesting, by 2004, the area of ​​natural Korean pine forest was only 40,000 hectares, with an accumulation of 6.45 million cubic meters. In order to better protect the resources of Korean pine, protect the ecological environment, and avoid the "hometown of red pine" into the "red pine story", after the municipal government proposed the "three nevers" principle in 2003, the city on August 25, 2004 The government issued the mayor No. 1 order and made a decision to stop logging natural pine forests in Yichun from September 1, 2004. The 2007 International Forum on Forest Ecological Protection (Yichun) and the International Conference on the Protection of Korean Pine were held successively, and the "Conservation of Red Pine Yichun Consensus" was published at the first Northeast Asian Ecology (Yichun) Forum. Yichun City and China Construction Bank jointly issued the first famous city card in China to protect rare trees, Hongsong Longka, and established a public welfare social group - Yichun Protection Red Pine Federation. The claiming of Korean pine is a public welfare social undertaking. It marks people's conscience and responsibility for the ecological environment and reflects goodness and public morality. The claiming of red pine has been recognized and praised by many people of insight and famous people at home and abroad; the claiming of red pine has moved from Yichun to the whole province, to the whole country, to the world. From November 2007 to January 2011, 320,000 red pines were actually claimed, and the total amount of red pine was 32 million yuan. Since the implementation of the Yichun Protection Pines initiative, the resources of the Korean pine forest have recovered to 114,000 hectares and accumulated 11.25 million cubic meters. With the continuous development of Yichun's protection of Korean pine, Yichun Hongsong is well known. As the core protection area of ​​Yichun Hongsong and the largest protection base, the five battalions also became famous. The Wuying Red Pine Seeds became a household name. In recent years, the municipal party committee and the municipal government have also promulgated the “Hongsong Industry Development Plan”. The Hongsong Fruit Forest Base is an important part of the “Seven Belts and One Valley” industry belt, which is the key construction of the city. The Korean pine nuts are the key products of the forest food northern medicine industry. One of the five major industrial chains of “red, blue and black + forest animals + forest medicine”. In recent years, Yichun City has successively introduced Zhongmeng Company and Huiyuan Group to invest heavily in the construction of Hongsong nuts deep processing project. The processing capacity of Korean pine nuts will reach 20,000 tons, and strive to make raw materials of Korean pine nuts before the arrival of a high yield year.

Technical requirements for quality of Wuying Hongsong seeds (1) Regional environmental conditions. Pinus koraiensis is mainly distributed in mountainous hills and grows on black loam with an average altitude of 300 to 400 meters. The five battalions belong to the northern cold temperate continental monsoon climate zone. The climate varies greatly throughout the year, the winter is long, dry and cold; the summer is mild, rainy, early spring low temperature, rainy and snowy, and the autumn cools rapidly, the annual average temperature is about -0.4 °C. The extreme maximum temperature is 36.5 ° C, the extreme minimum temperature is -40.7 ° C; the annual average rainfall is about 644 mm. (2) Harvesting. The best harvesting period of Wuying Hongsong seeds is after mid-September, and the fruit is harvested from Wuying natural red pine forest. (3) Storage and processing. 1. The harvested pine nuts are stored in a low temperature cold storage, and the temperature requirement cannot be greater than 10 °C. 2. After the pine cones are piled up for about 20 days, they are dried (or dried) and then threshed by a special machine. After threshing, the red pine seeds are placed in a drying chamber at 40 ° C to 55 ° C for drying or outdoor drying, and the water content of the red pine seeds is reduced to less than 10% and then sorted. 3. Grading screening: The dried red pine seeds are screened according to the particle size, which can be divided into four grades, the first sieve is more than 11.5 mm, the second sieve is 11.5 mm, the third sieve is 10.5 mm, and the fourth sieve is 9.5 mm. (4) Process flow. Cones → picking → threshing → drying (drying) → grading screening → manual selection → inspection → metering → packaging. (5) Quality characteristics. 1. Sensory index: The shape of the red pine seed is a triangular cone, the edge is obvious, the sharp angle at the top is small, and the sharpness is more obvious than other regions. The particles are larger, the skin is thicker, and the 1000-grain weight is above 400 grams. The seed rate is 75% or more. The fruit is reddish brown and the nuts are milky white. 2. Physical and chemical indicators: pure rate ≥ 90.5; water content ≤ 12; impurity rate ≤ 1.5; imperfect grain ≤ 3.0; protein ≥ 12.0; fat ≥ 70.0.
