A kind of rooting culture and seedling raising method of Thorn elm tissue culture seedling

Abstract

The invention discloses a method for rooting culture and seedling raising of Ulmus chinensis tissue culture seedlings, comprising the following steps: 1) selecting rooting materials; 2) rooting culture in a bottle; 3) hardening seedlings in a bottle; 4) tending seedlings in a nutrient pot, Ulmus chinensis seedlings were obtained; the method solved the problem of low seedling emergence rate of Ulmus chinensis by traditional sowing, cutting and grafting propagation, and the tissue cultured seedlings of Ulmus chinensis cultivated had more fibrous roots, strong root system vitality, dark green leaves and faster growth. It is fast, and can be directly planted without the washing process of general tissue culture seedlings, which saves labor costs and is more suitable for industrial scale production. The rooting rate of the cultivated tissue culture seedlings can reach more than 95.3%, and the survival rate can reach more than 96.9%. ; The present invention is applicable to the seedling raising of elm thorn tissue culture seedlings.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and relates to a method for rooting and seedling cultivation, in particular to a method for rooting cultivation and seedling cultivation of elm erythematosus tissue culture seedlings. Background technique [0002] Ulmus is a small deciduous tree of the family Ulmaceae, with a height of up to 10 meters, or in the shape of a shrub; it often grows in secondary forests on slopes below 2,000 meters above sea level; it is resistant to barrenness, drought, low temperature, and sandstorms, and is suitable for growth on various soils. It has strong adaptability, strong tillering ability, and slow growth rate. It can grow in areas with poor site conditions such as barren hills, barren slopes, and sandy land. Its role can be used firstly as a greening tree species for sand prevention and control, playing the role of windbreak and sand fixation, water and soil conservation, and water conservation; secondly, ...

AI Technical Summary

Problems solved by technology

However, seed propagation is prone to trait variation, which is not conducive to maintaining the excellent traits of the female parent; and the traditional asexual reproduction method, the female parent material cannot be obtained in large quantities, so the reproduction coefficient is low, the seedlings are slow, and a large number of seedlings cannot be provided, which limits its application.

[0004] At present, there are few research reports on Ulmus chinensis, only a small amount of research on traditional seedling cultivation, afforestation, biological characteristics, active substances, etc. There are almost no relevant reports on the research on tissue culture and rooting of Ulmus chinensis
