Nerium oleander seedling raising method by single-joint cuttage

Abstract

The invention discloses a Nerium oleander seedling raising method by single-joint cuttage, which uses cuttage with Nerium oleander shoots and includes: firstly, cutting a shoot from a mother shoot, cutting the shoot into segments to obtain cuttings, reserving one to three leaves, keeping moist and carrying outdoors; secondly soaking the cuttings in water for 5-10 minutes, inserting the cuttings into a nutrition pot, a tray or a seedbed, and fully exposing the leaves from the surface of substrate; and thirdly, spraying water to the leaves to keep moisture, allowing the leaves to exposed to light, controlling the temperature, and reserving a joint on each cutting segment; wherein when two leaves are left in the first step, the cutting is soaked in the water for 8 minutes. The method has the advantages that cuttage time is free and less affected by seasons, materials are convenient to obtain, the high propagating coefficient is two to three times of that of the conventional methods, the number of seedlings raised by the method is one to two times of that of seedlings raised by the conventional methods, and the method is simple and convenient and easy in operation.

Description

technical field [0001] The invention relates to a method for raising seedlings of plants, in particular to a method for raising seedlings by cuttings. Background technique [0002] Most of the propagation techniques of mosaic oleander use the cutting method, and when the mosaic oleander is cut, many plant nurses practice: for example: Yue Shunxin and others use 2~ 3 nodes, Shen Shengchu et al. used 3 nodes for the fringe of the plant, Jiang Jianding et al. took 4 to 5 nodes; the above-mentioned people have many defects in the process of raising seedlings, mainly reflected in: when picking ears , because the number of nodes is too large, the utilization rate of branches is low, and the reproduction coefficient is not high enough. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to aim at the deficiencies of the prior art, and provide a novel method for raising seedlings by single-node cuttings of oleander. [0004] In order ...

Problems solved by technology

[0002] Most of the propagation techniques of oleander are cuttage method, and when cutting oleander, the practice of many plant seedlings is: for example: Yue Shunxin and others use 2~ 3 nodes, Shen Shengchu used 3 nodes for the spikes of plants, and Jiang Jianding et al. used 4 to 5 nodes; the above-mentioned people have many defects in the process of raising seedlings, which are mainly reflected in: when picking ears , due to the excessive number of nodes, the utilization rate of branches is low, and the reproduction coefficient is not high enough; it is difficult to carry out a large number of seedling raising work in a short period of time for the method of Phyllostachys japonica
