Method for quick cutting rooting of wintersweet

Abstract

The invention discloses a method for quick cutting rooting of wintersweet. The method comprises the following steps: supplementing nutrition of a scion picking garden, paving a cutting bed, preparinga gel rooting agent, treating cutting slips, carrying out cutting and carrying out management after the cutting; wherein a cutting rooting agent is added into a water solution prepared by mixing polyvinyl alcohol with glycerin for obtaining the gel rooting agent, nutrition is supplemented to a wintersweet mother tree, the wintersweet mother tree is cut into cutting slips, then the cutting slips are soaked into the gel rooting agent to coat the surfaces of the cutting slips with a layer of cutting rooting agent film, and then cutting and cutting management are carried out. The method has the beneficial effects that the rooting agent film on the surfaces of the cutting slips has a water retention function, the gel rooting agent film on of overground parts can reduce the water evaporation ofthe cutting slips and prevent the cutting slips from withering and diseases, the gel rooting agent film of the underground parts can absorb water in a cutting matrix to keep a wet state, and meanwhile, a rooting agent is slowly released for stimulating the rooting of the cutting slips and improving the rooting number, the root length and the root thickness of the cutting slips, so that the cuttingsurvival rate is improved.

Description

technical field [0001] The invention relates to the field of plant propagation, in particular to a method for rapid cutting and rooting of wintersweet. technical background [0002] Wintersweet, Wintersweetaceae, deciduous shrub, often clustered, leaves opposite, elliptic-ovate to egg-lanceolate, flowers born in the leaf axils of the second-year branches, flowers first and then leaves, 2-4 cm in diameter; flowers Tepals round, oblong, obovate, elliptic or spatulate, glabrous, filaments longer than or equal to anthers, anthers incurved, glabrous, style 3 times as long as ovary, base hairy, receptacle nearly Lignified, with a retracted mouth, and subulate-lanceolate coat epiphytes, flowering first in late winter. [0003] Wintersweet is native to the central part of my country. It likes sunshine, but it is also slightly shade-tolerant. It is more cold-resistant and drought-tolerant. Wintersweet is not strict on soil quality, but light loam with good drainage is suitable. Wi...

Problems solved by technology

[0005] There are many methods about the cutting technology of wintersweet, the Chinese invention patent of CN 104429508 B as authorized public number in prior art, discloses a kind of cutting propagation method of wintersweet, this inventive method is cutting matrix with peat soil, perlite, with Alcohol and indole acetic acid solution are used as rooting agents to stimulate cuttings to take root, which has the advantages of low cost and easy operation, but the inventive method only uses 2.5‰ indole acetic acid as rooting agent, which does not have antibacterial and antiseptic effects, and indole acetic acid is easy to Decomposition reduces its effectiveness. The rooting agent does not have the function of water retention and slow release. When the young roots have not grown and the concentration of indole acetic acid is very low, the survival rate and rooting rate of the cuttings are not high, so the cutting effect is not good.
