Method for raising liquidambar styraciflua seedlings by virtue of grafting

Abstract

The invention provides a method for raising liquidambar styraciflua seedlings by virtue of grafting and relates to the technical field of red maple seedling raising. The method is characterized by comprising the following steps: (1) tree stock and scion selection, namely selecting an acer mono seedling which grows strongly as a tree stock and an annual red maple branch as a scion; (2) grafting time and method, namely cutting the red maple branch to 8-9cm during the period from the last third of March to the first third and middle third of April, dipping a molten paraffin solution to form a thin paraffin layer on the surface of the branch; (3) approach grafting, namely putting the acer mono which is planted in a pot in the first year and serves as the tree stock beside a red maple mother plant, selecting a red maple branch with thickness similar to that of the tree stock, cutting grafting parts of the tree stock and the scion to parts which are 2.5-3.5cm below cambium layers, prying out barks, then aligning and adhering two cambium layers at the cut surfaces of the tree stock and the scion together; (4) management after grafting. The method is relatively simple in operation, short in seedling raising period, strong and tidy in seedlings and free from weak seedlings and can be used for greatly improving the production efficiency and the economic benefits.

Description

technical field [0001] The invention relates to the technical field of red maple seedling cultivation, and relates to a method for grafting American red maple seedlings. Background technique [0002] Red maple is a variant of chicken claw, with many varieties, and it is a very beautiful foliage plant. Its leaf shape is beautiful, palm-shaped 5-7 cracks, long-lasting red, neat branch order, clear layers, light and unrestrained tree posture, so it is widely cultivated. Red maple likes sunlight, is afraid of the scorching sun and the sun, likes warm and humid climate, is more cold-tolerant, slightly drought-tolerant; not waterlogging, suitable for fertile, loose and well-drained soil. [0003] American red maple, Aceraceae, also known as Canadian red maple, is native to the east coast of the United States and is a large deciduous tree. It grows fast, with an adult tree height of 12-18 meters and a crown width of 12 meters, which can adapt to the growth of various soil types. ...

AI Technical Summary

Problems solved by technology

Most of the existing seedling raising methods of American red maple adopt the method of sowing or cutting seedlings. This method takes a long time to raise seedlings, and it takes several years to cultivate the whole big seedlings. Therefore, it is not conducive to the rapid release of seedlings on the market. It will lead to a reduction in its economic benefits, and the method of sowing seedlings tends to grow more weak seedlings, and it is difficult to keep the whole seedlings strong and tidy
