Description
Technical Field
The invention belongs to the technical field of rhododendron propagation, and particularly relates to a cutting propagation method of rhododendron in a high-temperature region in summer.
Background
At present, the current horticultural azalea cultivars in China are generally accepted to be divided into four strains of spring azalea, summer azalea, east azalea and west azalea according to the classification mode based on flowering phase and source (Changchang 2008).
East-ocean Rhododendron (short for east-azalea) refers to the variety of Rhododendron stonewort (Rhododendron obtusium) from Japan and its numerous filial generations, and east-azalea plants are short and short, mostly have transverse branches, and are thin and soft. The leaves are light green, the surface is glossy, the shape is oval, smaller, thinner and less hairy. The flower buds grow on the tops of branches, 1-3 small flowers exist in the common flower buds, 5 flowers can be obtained when the flower buds are more abundant, the flower amount is large, the flowers are more bright and brocade when the flower buds grow, and only the flowers can see no leaves, so that the gorgeous color effect can be formed. East azalea is an important garden plant, a high-quality bonsai manufacturing material and a favorite night flower. The east cuckoo has dense flowers in the flowering phase, larger flower amount than spring cuckoo and higher ornamental value than spring cuckoo, has stronger stress resistance and disease resistance compared with western cuckoo with higher ornamental value, and belongs to a strain with stronger resistance in a plurality of strains of cuckoo. Meanwhile, the rhododendron has strong adaptability, is easier to survive by introduction and domestication in different regions and climatic environments, keeps high ornamental value, is an excellent strain with high ornamental value, strong resistance, strong adaptability and easy management and culture among a plurality of rhododendrons, and has good application prospect and garden application value.
The propagation of horticultural azalea species is currently mainly by cutting propagation. Other propagation methods such as seed propagation have the problems of difficult germination, slow growth and difficult survival of seedlings; the grafting propagation method has the advantages of large workload, low survival rate and high operation technical requirement; the tissue culture propagation cost is high, and the survival rate of woody plants is low. Therefore, the cutting propagation has the characteristics of low cost, simple and convenient operation and large propagation amount, and is the most common propagation method for rhododendron production and propagation.
However, the research on the propagation technology of east cuckoo in China is still blank. Branches of east rhododendron are weak and are difficult to perform cutting propagation compared with other lines, the conventional cutting method adopts the annual semi-lignified branches for cutting, and the early summer from the middle of 5 months to the upper of 6 months is generally required when the annual new branches are lignified. The main areas of the east cuckoo, such as Ningbo, Jinhua and Jiashan, are areas with low temperature in summer, but for high-temperature areas in summer (the temperature exceeds 35 ℃ in 10 years and exceeds 200 days), such as Wuhan, the temperature can be suddenly increased in the first 6 th of month, the cutting spike is easy to die, and the cutting survival rate is extremely low. Aiming at the current situations that seed propagation of the domestic rhododendron anthopogonoides is difficult to germinate, the tissue culture propagation cost is high, the grafting propagation workload is large, and the excellent variety rapid propagation is not suitable, how to effectively improve the propagation survival rate of the rhododendron anthopogonoides, shorten the seedling period and reduce the production cost becomes a problem to be solved urgently in the industrialized development of the rhododendron anthopogonoides.
