Pingou hazelnut, whose scientific name is Corylus heterophylla Fisch X Corylus avellana L., is commonly known as hybrid hazelnut, hazelnut hazel, hazelnut hazelnut. It is a research group led by Prof. Liang Weijian of the Liaoning Institute of Economic Forestry and successfully cultivated after 20 years of breeding research. The source is the interspecific hybrid produced by C. avellana Fisch. as the parent and C. avellana L. as the male parent. ,strain.

The “New Variety Breeding Research on Hazelnuts” identified five new varieties in 1999 (more than 10 fine breeds and strains were introduced since 2002), and the experts' evaluations were internationally advanced and won the second prize for scientific and technological progress of the Liaoning Provincial Government. This innovative result is the first time in the world that a new cold-resistant, large-fruit hazelnut variety has been selected, and the cultivation area of ​​the large fruit hazelnut has been extended northward by 10 latitudes (36N-46N). Over the past few millennia, the production of hazelnuts in China has been wild, and now, the breeding success of hybrid varieties of Hazelnuts in Pingou is successful, and the production of hazelnuts in China has been transformed from wild to horticultural cultivation.

Pingou Hazelnut New Variety Characteristics

(1) The nuts are large, the single fruit weight is 2.0~3.5g, which is 2~3 times of that of the wild hazelnuts; the kernel rate is as high as 40~50% (the wild flat hazelnut kernel rate is about 30%), and the nut flavor and nutrient ingredients are superior Imported European hazelnuts. (2) Early results and high yields. Results of 2-3 year old saplings. 40 to 60 kg per mu for 4 to 5 years, 120 to 150 kg for 6 to 7 years, and 150 to 200 for 8 to 10 years. kg. (3) cold resistance, strong adaptability. Pingou hazelnut tree can tolerate -30 °C ~ -35 °C low temperature in winter, adapt to a variety of soil growth and solid, soil PH5.5 ~ 8, in China's widely cultivated areas, 32N-46N, that is, north of the Yangtze River to Jiamusi in Heilongjiang Can be cultivated. (4) Less pests and diseases, management and labor saving, low cultivation costs, and high economic benefits.

National cultivation status

By the end of 2009, the country had cultivated about 40,000 mu, of which 31,000 were in Liaoning. The total annual production is about 30 tons, most of which are in Liaoning.

Eighteen provinces and cities north of the Yangtze River in China (Liaoning, Heilongjiang, Jilin, Hebei, Beijing, Tianjin, Inner Mongolia, Shandong, Henan, Shanxi, Shaanxi, Ningxia, Gansu, Xinjiang, Jiangsu, Anhui, Zhejiang, and Yunnan) have been introduced, of which Heilongjiang , Jilin, Xinjiang, Beijing introduced more.

Wide prospects for cultivation

Pingou Hazelnut is rich in nutrients, not only a delicious dried fruit, but also a raw material for food processing. It can be used to make hazelnut chocolate, candy, cakes, ice cream and other foods. The economic benefits of cultivation of Hazelnuts from Europe are high. According to the preliminary test, the average annual net income per mu in cultivated flat hazelnuts is between 2400 and 4,000 yuan. Hazelnuts have a wide market, and in addition to a large amount of domestic demand, the international, Italy, the Netherlands, and Southeast Asian countries all have great demand and have a broad cultivation prospect.

Royal Jelly is also called Bee Milk. The fresh royal jelly is slightly ropy milk paste  substance; it is the excretive mixture of nutrition gland and maxilla gland of the head of little worker bee. The worker bees use this to feed the 1-3 days` worker bee larva and drone larva, 1-5.5 days` queen bee larva and queen bee in the oviposition period. The royal jelly is the biologic product containing very complicated active elements which contains almost all the nutrition elements required by the growth of the human body.
