Abstract

The invention discloses a hormone hydrogel rooting film, which is prepared by the steps of: swelling polyvinyl alcohol at normal temperature for 30min, and heating for completely dissolving polyvinyl alcohol to obtain a transparent liquid; cooling, adjusting the pH value of the solution with concentrated hydrochloric acid, adding glycerol and reacting to prepare a hydrogel liquid; and adding hormone to the hydrogel liquid and stirring. When in use, the hormone hydrogel rooting film is spread on the surface of a hard branch cutting shoot, so that a gel film is formed on the surface of the hard branch cutting shoot above the ground so as to achieve the purpose of reducing the moisture of the cutting shoot from dissipation, and a gel film is formed on the surface of the hard branch cutting shoot under the ground so as to keep a moisture state in soil and play a role of slowly releasing hormone to stimulate the rooting of the cutting shoot, thus the rooting critical stage of the hard branch cutting shoot is prolonged and the rooting survival rate of the hard branch cutting shoot is improved. The technical scheme disclosed by the invention is simple and convenient, high in raising seedling survival rate and significant in economic and social benefits, and saves seedling-raising investment by more than 10%.

Description

The hormone hydrogel film of taking root

Technical field

The present invention relates to trees hardwood cutting and seedling raising field, especially relate to the hormone hydrogel film of taking root.

Background technology

Cuttage is one of vegetative common method of trees, and it is low to have a production cost, and reproduction speed is fast, and the branch source is abundant, can keep advantages such as maternal merit.Some seeds such as land for growing field crops hardwood cutting and seedling raisings such as American-European poplar, willow that are prone to take root have been a conventional ripening technology.But seeds that some are difficult to take root such as ginkgo, elm, Chinese white poplar, jujube tree etc. are adopted the technical barrier of hard stem cutting fringe direct cuttage and seedling culture under field condition, are never solved preferably.Owing to lack ready-made root initial body in the difficult seeds branch of taking root; Needing to insert fringe base portion callus forms; Part dissolves the root initial body within it again; The root initial body is further grown and could be formed adventive root, and often in very long rooting process, slotting fringe is impatient at moisture and waning of nutrition and is caused death.In order to improve the difficulty hard stem cutting fringe of the seeds root survival of taking root, prior art adopts root-promoting hormone, nutriment, emerge in worm water usually, insert fringe processing method such as stores away in winter, and improves the cuttage rooting hormonal readiness, reduces to insert fringe and suppress to take root content of material; Employing urges methods such as root, plastic mulching, little shed, greenhouse, humidification shelter from heat or light to prolong the cuttage rooting critical period.Though improved the cuttage rooting survival rate, there are shortcomings such as many, the difficult grasps of technical step, instability, cost height in the above technical measures of integrated use, and production effect is unsatisfactory.

Summary of the invention

The object of the invention is to provide a kind of hormone hydrogel that improves cuttage rooting survival rate film of taking root.

For realizing above-mentioned purpose, the present invention can take following technical proposals:

The hormone hydrogel of the present invention film of taking root, according to following proportioning raw materials and step preparation:

The weight portion proportioning of a, raw material:

Water: 800-1200; Polyvinyl alcohol: 60-90; Concentration is 2.5% glycerine: 30-45; Hormone: 0.08-0.2;

Described hormone is by indolebutyric acid sylvite, methyl sodium salt, diethyl aminoethyl hexanoate (chemical name: diethylamino ethanol caproate) according to the weight portion ratio mixed preparing of 10:50:3;

B, preparation process:

The first step, Jiang Shui place in the container, add the polyvinyl alcohol swelling and after 30 minutes container are placed in the water-bath, heat to 80-90 ℃, make polyvinyl alcohol be dissolved to transparency liquid fully; Be cooled to 60 ℃ then, with concentrated hydrochloric acid regulator solution pH value to 1-2;

Second step, in first step gained solution, to add concentration be 2.5% glycerine reaction 50-70 minute, is cooled to 30-40 ℃, makes gel aqueous fluid;

The 3rd step, in the second step gained gel aqueous fluid, add hormone and stir and promptly get.

The invention has the advantages that from water conservation, short root aspect and take measures, make gel aqueous fluid with polyvinyl alcohol and glycerine reaction, is that carrier adds said root-promoting hormone with the gel aqueous fluid.During use; It is coated in hard stem cutting fringe surface, promptly forms thin film after the hydrogel drying, like this on hard stem cutting fringe surface; Be in above hard stem cutting fringe surface, ground and form glued membrane to reach the slotting fringe moisture loss purpose of minimizing; And the formed glued membrane in hard stem cutting fringe surface that is in below ground is moisture state in soil, plays the hormonal stimulation cuttage rooting effect that slowly releases, thus reach prolong hard stem cutting fringe take root critical period, improve the purpose of hard stem cutting fringe root survival.Test shows; The hormone hydrogel of the present invention film of taking root is coated in the ginkgo spring and adopts and insert the fringe surface; Take open country cuttage and seedling culture root survival to reach 94.2%, quite store away in winter and insert fringe and soak ABT root-inducing powder 100mg/kg solution 4 hours open countrys, plastic mulching cuttage and seedling culture cuttage rooting survival rates and improved 50.0%, 14.2%.The gold leaf elm is adopted the spring of the present invention to adopt to insert fringe open country cuttage and seedling culture cuttage rooting survival rate and reaches 90.0%, quite stores away in winter to insert fringe and soak ABT root-inducing powder 100mg/kg solution 4 hours open countrys, plastic mulching cuttage and seedling culture cuttage rooting survival rates and improved 68.9%, 46.7%.Technical scheme of the present invention is easy, and survival rate of seedling is high, and practicing thrift grows seedlings drops into more than 10%, and economical, societal benefits are remarkable.
