Embodiment Construction

[0012] The present invention will be further described in detail below in combination with specific embodiments.

[0013] A method for growing seedlings of oleander cuttings, comprising the following steps:

[0014] A. Select cutting objects: use last year's branches in spring, and use fully lignified current year's branches in summer and autumn.

[0015] B. Ear picking and splitting: cut the branches from the mother tree and keep them moist; cut the branches indoors into sections, which are ear sections, leave one section for each section, and split the ear section into 3 pieces with a sharp knife. Contains one bud and moisturizes; each piece is a cutting. When cutting the ear segment, generally the upper cut is closer to the node (bud), while the lower cut should be farther away from the node (bud), so that the cuttings can be inserted into the matrix. At the same time, be careful not to hurt the bud eyes and the retained leaves, and try to avoid peeling of the bark.

Abstract

The invention relates to a method for culturing a cutting seedling of Nerium oleander. The method comprises the following steps of: 1, selecting a cutting object, wherein last-year old branches are selected in spring, and fully-lignified current-layer fresh branches are selected in summer and autumn; 2, taking spikes and splitting the branches, namely cutting off the branches from a mother tree, preserving moisture, cutting the branches into segments indoors to get spike segments, splitting each spike segment into 3 pieces by a sharp knife and preserving moisture, wherein each segment keeps a section and each piece contains a sprout; 3, soaking cuttings split in the step 2 in clear water to wash part of juice and suck moisture, and inserting the cuttings into a nutrition bowl or a culture disc or a seed bed, wherein leaves are exposed out of the surface of a substrate; and 4, performing post insertion management, namely keeping soil moisture, frequently spraying water on the leaves to prevent the cuttings from water loss, controlling the temperature to be below 35 DEG C and shading to prevent strong sunlight. The method has the advantages of fully utilizing cutting materials, improving reproduction coefficient to the largest extent, along with simple and convenient technology and easiness of operation.

Description

(1) Technical field [0001] The invention relates to a method for cultivating oleander seedlings. (2) Background technology [0002] Oleander mosaic is an evergreen shrub with 3 whorls of leaves, and occasionally 4 whorls. It is propagated by cuttings, and 2 to 3 or even more branches are cut as cuttings. The above-mentioned fringing method has a low branch utilization rate and a low propagation coefficient, so it is difficult to carry out a large number of seedling cultivation work in a short period of time for the excellent new colorful leaf tree species of oleander. (3) Contents of the invention [0003] In order to overcome the above-mentioned disadvantages of the existing methods for growing oleander seedlings, the present invention provides a method for raising seedlings by cutting oleander with simple technology, easy operation, full use of cutting materials, and maximizing the propagation coefficient. Its keywords include "oleander", "vegetative propagation" and "s...
