Problems solved by technology

But its defect is that it is not very cold-resistant, and it can only be grown in Guangdong, Guangxi, Hainan, Fujian, Hunan, southern Jiangxi, Yunnan, Guizhou, and southwestern Sichuan between 19-26 degrees north latitude and 105-120 degrees east diameter. The area with relatively low temperature between 26-30 degrees north latitude is seldom planted, and this area has more rain all year round, and the land is fertile, neutral and slightly acidic, which is especially suitable for the growth of eucalyptus. If eucalyptus can be introduced to this place , will make a significant contribution to the development of the local economy and the improvement of people's living standards Type the technical field description paragraph here

specific Embodiment approach

[0019] [Specific embodiments] The present invention is further described by the above examples:

[0020] The inventor used 500 mu of barren hills in Lixian County, Hunan Province to try to plant "Xiang Eucalyptus No. 1". After three years of planting and management, it has grown into a large piece of Eucalyptus forest with an average tree height and diameter at breast height of 13m and 12cm respectively. The growth is lush and the growth is gratifying. The method is as follows:

[0021] 1. Determining Eucalyptus species: Determining Dunn’s Eucalyptus as the best tree species,

[0022] 2. Breeding process of cold-resistant "Xiang Eucalyptus No. 1":

[0023] 1. Preparation and sterilization of culture medium: Take out various mother liquors from the prepared mother liquor, then add sugar, carrageenan and water to stir evenly, adjust the pH value, divide the culture medium into culture bottles, and put them in the pressure steam Sterilize in the sterilizer. When the pressure in...

Abstract

The invention discloses a method for breeding a cold-resistant eucalypt Xiang eucalypt No.1 variety suitable for the north latitude 26 to 30 degrees. The method comprises the following steps of: determining Eucalyptus dunnii as a eucalypt variety, sterilizing a culture medium, sterilizing and disinfecting before inoculation, inoculating, subculturing, performing rooting culture, performing seedling culture, and culturing young seedling and sapling, wherein the inoculation is performed by the following steps of: (1) scissoring robust semi-lignified sprout branches, preserving heat with clean gauzes or sealing with clean gauzes for moisturizing, and bringing back to a room at a sunny noon or afternoon; (2) cutting away all leaves, leaving a small number of leaf stalks, soaking in 0.1 percent mercuric chloride solution for 3 to 12 minutes section by section according to the lignification degree of the branches, and washing with sterile water for 4 to 5 times; and (3) cutting stalk sections with sprouts, wherein the stalk sections are 1 to 2 centimeters and the branches of the upper branch sections of lateral buds are about 0.5 centimeters, inoculating on a culture medium of a 3 / 4ms+0.5 milligram / L IBA+0.3milligram / L NAA culture bottle, controlling the temperature to be 22 to 27 DEG C and illumination intensity to be 2,000 lx, and inducing the lateral buds to germinate.

Description

technical field [0001] The invention relates to a breeding method for eucalyptus varieties, in particular to a breeding method for the cold-resistant eucalyptus Xiangeucalyptus No. 1 variety suitable for 26-30 degrees north latitude. Background technique [0002] Eucalyptus is an evergreen broad-leaved fast-growing tree of the family Myrtaceae, native to Australia, Indonesia and the Philippines, and is one of the three famous fast-growing tree species in the world. It grows into a forest in one year, matures in three years, and is harvested in five years. It grows rapidly, and its wood is hard and delicate, so it has great commodity value. It is not only the best raw material for making furniture and artificial boards, but also pulp in the paper industry. But its defect is that it is not very cold-resistant, and it can only be grown in Guangdong, Guangxi, Hainan, Fujian, Hunan, southern Jiangxi, Yunnan, Guizhou, and southwestern Sichuan between 19-26 degrees north latitude a...
