Example

[0036] Example 1: In early November 2006, common camellia seeds were used for seed germination, and the breeding anvil was sown in January 2007. The nutrient soil in the container was mixed with the following mass percentages of raw materials: soil miscellaneous fertilizer 60%, turf plaster 30% %, mature manure 7% and superphosphate 3%. After the young stocks were cultivated for 4 months, the semi-lignified branches of the excellent clones of Camellia oleifera were used as the scion (leave all leaves). The grafting was carried out by splitting in mid-May. The survival rate was investigated 25 days after the grafting. The survival rate reached 86.6%. After removing sprouts, topdressing root fertilizer, foliar fertilization, pest control and other management work, 88.3% of grafted container seedlings reached the standard of qualified seedlings in March of the following year, and the afforestation survival rate reached 95.7%.

Example

[0037] Example 2: Put the nutrient soil made by mixing and retting the following mass percentages of raw materials into each container: 70% soil miscellaneous fertilizer, 20% turf stucco, 7% decomposed bran cake fertilizer and 3% superphosphate. In December 2007, the seedlings were sown and cultivated with ordinary oil-tea camellia seeds. In July of the same year, the 6-month-old ordinary oil-tea camellia seedlings were used as rootstocks. Two superior clones of Cenruan 2 and Cenruan 3 selected by Guangxi Academy of Forestry were used. The branches are scions (leave all leaves) and are grafted by splitting. Foliar spraying of plant cytokinin was started 15 days after grafting, once every 7 to 10 days, and other management measures were the same as in Example 1. An investigation was conducted 20 days after grafting, and 83.2% of the grafted plants produced callus, 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...
