Problems solved by technology
Due to the unstable firmness of this tree species and the difficulty in collecting seeds, it is difficult to provide stable seedlings for afforestation of this tree species, which affects the selection and breeding of excellent provenance resources of this tree species. However, the cutting survival rate is low (usually less than 50%). Therefore, the present invention explores the cutting seedling raising technology of this tree species by improving the sterilization and rooting induction technology, so as to improve the cutting survival rate and build a large area of Viburnum plantation Provide excellent seedlings

Embodiment
[0018] The 5-year-old viburnum with strong growth, uniform internode development and no pests and diseases was selected as the mother tree for picking ears. Cut young shoots from the mother tree that grow vigorously, have uniform internode development, and have just begun to lignify as cuttings. Cut the collected cuttings into cuttings with a length of about 8-10 cm, cut the upper end of the cuttings flat, and cut the lower end obliquely at 45°. It is required to have 2-3 axillary bud points on each cutting, keep 1 / 4 of the leaves on the cuttings, and keep 1 / 3 of the leaf area of each leaf. The cutting time of the cutting scion is August 13, 2015.
[0019] The light substrate produced by Fujian Nanping Senke Company was used as the cutting substrate, and the cutting light substrate was sterilized with 0.1% potassium permanganate for different periods of time before cutting. The sterilized light matrix is packed into a non-woven container bag with a specification of 3.5 c...

The invention relates to a seedling growing technology for increasing the survival rate of zenia insignis cuttings. To improve the survival rate of cuttings is the key technology of large-area popularation of zenia insignis afforestation, by means of an improved cutting substrate sterilization and cutting slip rooting induction technical method, the cutting seedling growing technology of the tree variety is discussed, and high-quality clonal seedlings are provided for creating a large-area man-made forest. By means of the technical scheme, different cutting substrate sterilization and cutting slip rooting induction time durations are set. According to different combination test formulas of fungicide types, fungicide solution concentrations, induction hormone types and induction hormone solution concentrations, zenia insignis substrate sterilization and cutting slip rooting induction are carried out; by arranging a contrast group (CK), namely distilled water, ten combination formulas are obtained in total; it is found that through the T6 treatment of 23-25 hours of substrate sterilization and 38-42 minutes of hormone induction, the survival rate of zenia insignis can be effectively and stably increased. The technology has the advantages that the survival rate of zenia insignis cuttings can be increased and is stable, and high-quality nursery stock can be provided for large-area popularization of zenia insignis afforestation.
Description
technical field [0001] The technical invention belongs to the technical field of plant seedling raising, and in particular relates to a seedling raising technology for improving the survival rate of Viburnum cuttings. technical background [0002] Zenia insignis (Zenia insignis) is a tall deciduous tree of the genus Zenia in the family Hematoxylinaceae. It is a rare tree species that can be excavated and utilized in southern my country, and it is a national second-class rare and endangered plant. This tree species has many excellent characteristics such as straight trunk, rapid growth, strong germination, good natural regeneration, strong resistance, and resistance to barrenness. Ideal for tree species. Due to the unstable firmness of this tree species and the difficulty in collecting seeds, it is difficult to provide stable seedlings for afforestation of this tree species, which affects the selection and breeding of excellent provenance resources of this tree species.
