Recently, a message came out from the Hickory Research Institute of Zhejiang Forestry College: After many years of research, the researchers of this institute finally managed to overcome the difficulties, successfully cloned the gene for flowering of hickory, and basically grasped the flowering mechanism of hickory. At present, almost all the hickory trees are pure wild, in the wild state of hickory, both need ventilation, moisturizing soil, but also afraid of water, currently only concentrated in the southeast of Anhui and western Zhejiang Tianmu Mountain 100 meters to 1200 meters above sea level Department. In general, it takes about 10 years for the hickory to reach the fruit from the seedlings, and most hickory trees are more than ten meters high. Picking is very difficult. In addition, there are many pests and diseases in hickory, and the yield is unstable and the quality is difficult to guarantee. The annual output of pecans in the country is less than 12,000 tons, making the price of pecans on the market high. The price per kilogram is as high as 80 yuan. In order to solve the problems such as improved varieties of pecans, dwarf trees, shortened childhood period and efficient cultivation, the Zhejiang Provincial Natural Science Fund Committee specially set up a research project. Zhejiang Forestry College is responsible for carrying out research on the genetic basis and optimization control of pecan quality, yield, and yield. Since 2003, Zhejiang Forestry University has established the Hickory Research Center, and has established 570 mu grafted seedling test base, 155 mu germplasm resource collection nursery, 86 mu seedling breeding base, and 100,000 Hickory grafted seedlings. Provincial science and technology innovation service center and a national scientific and technological achievement transformation center. Research experts have focused on the key issues that have severely hampered the development of the hickory industry. After three years of technical research, they have tackled the problems of grafting, dwarfing, seedling cultivation, and other issues of hickory, which have resulted in a large-scale planting and improved quality of hickory. may. At the same time, the Institute successfully cloned Hickory Homologous Flower Genes and completed and mastered the flowering mechanism of Hickory. The mastery of this technology will enable Hickory's fruiting time to advance from 8 to 10 years to 6 years, and it can also improve the yield and quality of Hickory by controlling the flowering genes, and prevent and control related pests and diseases. The significance.
