Non-woven fabric container cutting seedling raising method of Fraxinus velutina twigs

Abstract

The invention discloses a non-woven fabric container cutting seedling raising method of Fraxinus velutina twigs. The non-woven container cutting seedling method includes the following steps: (1) preparing cutting media: the cutting media are formed by preparing the following raw materials according to the volume percent: 15-25% of perlite, 5-15% of vermiculite, 65-75% of turfy soil, 2-7% of bagasse and 3-8% of saw dust, and spraying carbendazim solutions on the cutting media for disinfection; (2) preparing rooting agents: dissolving 100-400mg naphthylacetic acid in 40-50mL 95% ethyl alcohol, filling in 20-30mg 2,4-dichlorophenoxyacetic acid, 5-10mg zinc nitrate, 5-10mg nitric acid molybdenum, 5-10mg lanthanum nitrate and 40-50mg boric acid, filling in water until the solutions are at 1,000mL, and evenly mixing the solution; (3) preparing and treating cutting slips; (4) inserting the cutting slips into the cutting media, wherein the cutting depth is 8-9cm; (5) moving the non-woven fabric seedling raising container into a greenhouse, and erecting a shading screen for shading, wherein the shading percentage is 60-70%, the indoor temperature is kept at 26-29 DEG C, and the humidity is kept at 85-90%. The non-woven fabric container cutting seedling raising method of Fraxinus velutina twigs improves the survival rate and ensures to cultivate robust high-quality seedlings.

Description

technical field [0001] The invention relates to a method for growing seedlings by cuttage in a non-woven fabric container of fluffy white wax twigs, and belongs to the technical field of plant asexual reproduction. Background technique [0002] White wax is a general name for plants of the genus Fraxinus in the family Oleceae. There are about 70 species in the world, and about 34 species in my country, of which about 10 species are imported from abroad. There are many kinds of ash trees, with strong adaptability, good material and wide application. Among them, F. velutina grows fast and has a long life. It is a precious broad-leaved material and afforestation tree species with high economic value, and has strong Salt stress resistance is also an important tree species for afforestation in saline-alkali land. [0003] The traditional white wax propagation is mainly based on seed propagation. The seedlings are highly differentiated and cannot maintain the excellent characteri...

Problems solved by technology

In recent years, some progress has been made in the research on cutting propagation of Fraxinus Hulpehens is, Fraxinus griffithii, and F. mandshurica Rupr. in China. The research results are quite different. Propagation by conventional cutting and layering methods has difficulty in rooting and low reproduction coefficient, which cannot meet the demand for a large number of high-quality seedlings in production.

Zhang Jianguo et al. used fluffy white wax-Yuanwa No. 2 as the experimental material to carry out cutting experiments, and the average cutting survival rate reached 87.1%. However, this method does not rely on any technical means and is subject to certain restrictions on the cutting survival rate; Chinese patent application ( CN102742495 B) discloses a kind of sweet cherry dwarfing rootstock twig cutting non-woven container seedling raising method and matrix composition, which can improve the survival rate of twig cutting and seedling quality, but due to the different characteristics of sweet cherry and downy ash tree species, And white wax tomentosa is a tree species that is difficult to propagate by cuttings. At present, seed propagation or grafting is mostly used for propagation. The seedling cultivation period is long and the cost is high, which restricts the popularization and application of fine varieties of white wax towel.
