Qianshan Evening News (Reporter Wang Xin) A new agricultural plant variety, Qiante Fushou peach, was certified for cold resistance by the National Science and Technology Achievement Review Committee’s Forestry and Fruit Group yesterday, becoming the first in the country that can survive the winter. peach tree varieties. The suitable peach planting area has also moved north from Dalian to Anshan, breaking through the 1 latitude and 22 minutes of the northern line of the nationally designated peach planting climate suitable area. In 1981, when the teacher Chen Fugui was breeding Qianshan peach, he discovered that a mutant peach tree was significantly different from the Qianshan peach. It was a late-maturing variety and had a large fruit with a small core, fragrant fruit flavor, sweet and crisp taste, and soft and juicy flesh. From then on, He began to study this special peach tree intently. Chen Fugui chose two methods of propagation. The first was to use peach pits for pollination and propagation, and found that the fruit was unstable and had relatively large variations. The second was to propagate by grafting, and there was basically no variation in the fruit. The grafting was a complete success. The heaviest single peach grown is 410 grams, and the average weight is 250 grams. In 1998, the Anshan Municipal Science and Technology Bureau initiated research on this project and named it "Shishengwantao". After several years of research, the trademark "Qiante Fushou" was successfully registered in 2001, which means Qianshan's specialty Fushou peach. Chen Fugui also became In 2004, Qiante Fushou peach was recognized as a new agricultural plant variety by the Ministry of Agriculture. During this period, the cold resistance of Qiante Fushou peach was also fully tested. It withstood the severe freeze damage (minus 31°C) that occurred in Liaoning from 2000 to 2001 in 50 years. In July this year, it won the title of "Cold-resistant Shishengwan Peach". Cultivation Technology" invention patent. Since then, the suitable peach planting area has moved from Dalian north to Anshan, breaking through the 1 latitude and 22 minutes of the northern line of the nationally designated peach planting climate suitable area. Qiante Fushou peaches are planted in the same year and bear fruit in the second year. In the fourth year, the yield of each plant can reach about 25 kilograms. About 55 plants can be planted per mu, and the yield per mu can be as high as 1,400 kilograms. The maturity period is early September - around National Day. It is a late-maturing variety. It blooms when Nanguo pear is in full bloom and is just ripe when Nanguo pear is picked. At present, Qiante Fushou peach has been planted in dozens of acres in our city, and many "demonstration sites" have been expanded in other places, including Jinzhou, Huludao, Yingkou, Panjin, Liaoyang, Fushun and Beijing Xiaotangshan Special Vegetable Base As well as some cities in Shandong Province, Inner Mongolia, Jilin Province, Heilongjiang and other provinces and autonomous regions. The disadvantage is that the current output of Qiante Fushou peaches is still relatively low, and only a small part is supplied to the market.
