Preparation method of rooting agent for promoting winter sweet cutting

Abstract

The invention discloses a preparation method of a rooting agent for promoting winter sweet cutting. The method includes the steps of: preparing a ferrous chelating agent, compounding an auxin solution, and preparing a hydrogel rooting agent. According to the invention, the complex formed by an active polypeptide ferrous chelating agent and auxin can prevent auxin from photooxidation decomposition and lose of regulation effect, under appropriate conditions, decomplexation reaction can be carried out on the complex to release auxin and transform the auxin into free type, the free auxin can be transported to an action site to take effect, can prevent incisions from infecting pathogens and rotting, promote nursery stocks to generate calluses in advance, improve photosynthesis of flowers and trees, increase photosynthetic products, enhance water absorption and transportation functions, and reduce transpiration effect, thereby improving the cutting survival rate. The auxin hydrogel rooting agent is evenly applied on winter sweet cuttings, and a layer of thin auxin hydrogel rooting agent film can be formed after drying, thus being conducive to water maintaining and rooting agent release. Therefore, the rooting agent is an efficient winter sweet cutting rooting agent.

Description

technical field [0001] The invention relates to the field of preparation of rooting agents, in particular to a preparation method of an agent for promoting rooting of wintersweet cuttings. technical background [0002] Winter Sweet, also known as golden plum, wintersweet, wintersweet, and yellow plum, is a deciduous shrub of the genus Wintersweet in the family Wintersweet, about 3 meters high, often clustered, single leaves opposite, leaves oval-shaped or egg-shaped. Needle-shaped, apex acuminate, base round or cuneate, 7-15 cm long, entire, surface rough; bisexual flowers, solitary in the axils of annual branches and leaves, pedicel very short, yellow, waxy, fragrant. Wintersweet flowers are the first to bloom before spring, especially tiger-footed plums, which bloom in October of the lunar calendar, so they are called early plums; wintersweet flowers first and then leaves, and the flowers and leaves do not meet each other. Also known as Ganzhimei; the days when the winter...

Problems solved by technology

[0004] At present, there are many methods about the preparation technology of wintersweet cutting rooting agent, prior art such as authorized public number is the Chinese invention patent of CN104429508 B, discloses a kind of cutting propagation method of wintersweet wintersweet, this method uses indole acetic acid alcohol solution as rooting agent , cutting after soaking wintersweet cuttings has the advantage of simple operation, but the rooting agent only contains indole acetic acid as a growth-promoting substance, and its rooting-promoting effect is limited, and indole acetic acid is easy to photodecompose and thus loses its effectiveness. It does not contain antibacterial, anti-inflammatory and antiseptic effects, which makes the cuttings of wintersweet cuttings susceptible to infection and rot, so its application value is limited
