Problems solved by technology

At present, the Camellia oleifera grafting and propagation method mainly adopted in my country is the "Camellia oleifera bud seedling grafting" method successfully researched by the Subtropical Forestry Research Institute of the Chinese Academy of Forestry in the 1970s. The management technology requirements are relatively high, which has certain restrictions on the popularization and promotion of its technology and the vigorous development and application of the grafted and propagated seedlings of Camellia oleifera.

example 1

[0036] Example 1: In the first ten days of November 2006, ordinary Camellia oleifera seeds were used for seed germination, and in January 2007, the anvils were sown. The nutrient soil in the container was made by mixing the following raw materials in mass percentages: 60% soil miscellaneous fertilizer, 30% turf plaster %, decomposed manure 7% and superphosphate 3%. After 4 months of cultivation, the semi-lignified branches of Camellia oleifera clones were used as scions (the whole leaves were left), and were grafted by split grafting in mid-May. After 25 days of grafting, the survival survey was carried out, and the survival rate reached 86.6%. After germination removal, topdressing root fertilizer and foliar fertilization, pest control and other management work, 88.3% of the grafted container seedlings reached the standard of qualified seedlings in March of the second year, and the survival rate of afforestation reached 95.7%.

example 2

[0037] Example 2: Put the nutritious soil made by mixing and retting the following raw materials into each container: 70% soil miscellaneous fertilizer, 20% turf plaster, 7% decomposed bran cake fertilizer and 3% superphosphate. In December 2007, ordinary Camellia oleifera seedlings were sown and cultivated. In July of the same year, 6-month-old ordinary Camellia oleifera seedlings were used as rootstocks, and two fine Camellia oleifera clones, Cenruan 2 and Cenruan 3, were bred by Guangxi Academy of Forestry. The branches are scions (full leaves are left), and are grafted by split grafting. Fifteen days after grafting, plant cytokinin was sprayed on the leaves for 3 times, once every 7 to 10 days, and other management measures were the same as in Example 1. After 20 days of grafting, a survey was carried out, and 83.2% of the grafted plants produced callus tissue, and the grafted interface healed well.

Abstract

The invention relates to a propagation method for using an oil-tea young anvil to graft containerized seedlings. The propagation method comprises the main operating steps of: firstly culturing the young anvil, doing well in arrangement work of seedbeds and containers after selecting nursery lands, and selecting common oil tea seeds in the oil-tea species to carry out seeding and culturing the anvil; then carrying out operation of grafting and propagating again, firstly establishing pergolas, then carrying out grafting, taking seedlings in four to six months as stocks, adopting excellent clonal branches of oil-tea from hemilignification to lignification as scions, carrying out grafting in proper phenological period of the oil tea, moisturizing by an arch cover immediately after being grafted, keeping the moisture in the arch cover to be 80 percent to 90 percent, and doing well in real-time sprout removing, fertilizer water management and prevention of pests. The propagation method has long grafting seasons, simple cultivation method and easy promotion and scale production, has more than 95 percent of forestation survival rate and greatly improves the economic value of development and application of good seeds of the oil tea.

Description

technical field [0001] The invention relates to a propagation method of forest trees, in particular to a propagation method of camellia oleifera seedlings grafted into container seedlings. Background technique [0002] The production of camellia oleifera in my country has long been "deep-rooted" in the way of sexual reproduction (seed propagation), which is the main reason for mixed varieties of camellia oleifera, mixed good and bad, inconvenient management, and low yield. However, with the in-depth development of improved breeding research and the continuous generation of excellent clones, as well as the coordinated research of the majority of scientific and technological workers, the technical difficulties of Camellia oleifera vegetative reproduction have been gradually solved and have been popularized and applied in Camellia oleifera production, which has led to the improvement of Camellia oleifera production. opened the way. Among them, cutting, grafting and tissue cult...
