Grafting and seedling-cultivating method for Theaceae plant

Abstract

The invention provides a grafting and seedling-cultivating method for a Theaceae plant. A grafting and seedling-cultivating manner of the grafting and seedling-cultivating method is that seeds of the Theaceae plant are refrigerated; pre-germination is conducted in due time according to the shoot growing condition of a scion supply plant at every time, and the pre-germinated seeds are cultivated into root stocks in a seedling cultivating container; and a root stock 1.2 to 2.0mm in diameter is selected, and the upper end of the root stock is cut off at a distance of 3 to 5cm from the ground, so as to graft the root stock. The method provided by the invention is particularly suitable for the grafting and seedling cultivation of oil camellia and has the advantages that the grafting can be realized for multiple times within one year, so that the seedling cultivation cost is effectively reduced; through selecting and grafting appropriate root stock materials, the grafting survival rate is effectively increased; and through appropriately controlling conditions of pre-germination, seedling cultivation, and the like, the seedling cultivation period is effectively shortened.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for growing seedlings by grafting plants. Background technique [0002] Grafting is one of the artificial vegetative propagation methods of plants, which is to graft the branch or bud of one plant to the stem or root of another plant, so that the two parts that are joined together grow into a complete plant. When grafting, the scion should be closely combined with the cambium of the rootstock to ensure the survival of the scion. The connected branches or buds are called scions, and the grafted plant body is called rootstock or platform wood. [0003] The propagation method of camellia oleifera grafting is to graft the branches of excellent mother trees to the anvil of camellia oleifera seedlings with taproot, and produce callus through the cambium cells at the interface of the anvil and ear incision, so that the joints become a unified new plant. At pre...

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. This method greatly improves the grafting survival rate of Camellia oleifera and However, in the long-term production practice, some factors restrict the popularization and promotion of grafted seedlings and the vigorous development and application of grafted seedlings of Camellia oleifera: 1. The traditional method of grafting seedlings needs to take out the rootstock from the sand bed and put it in the Grafting on the desktop, this method will cause serious damage to the root system, and the root system will take a long time to recover and grow; 2. It is difficult to control the thickness of rootstock seed development in traditional grafting seedlings, which affects the grafting efficiency; 3. Traditional ground planting In the process of seedling raising, the root system of the plant is destroyed, which affects the survival rate of uphill afforestation; 4. The cultivation of rootstock is limited by a certain time, limited to spring, which limits the time for breeding and raising seedlings
