preparation Embodiment 1

[0039] In a 30-liter reactor, 0.36 kg of polyvinyl alcohol and 0.18 kg of sodium carboxymethylcellulose were heated and stirred in 12 liters of water to prepare an aqueous suspension of the film-forming agent. The resulting film-forming agent aqueous suspension and 6 liters of salt-dissolving growth-promoting bacteria and combination growth-promoting growth-controlling bacteria fermented liquid (about 10 12 cfu / ml) in a reactor with mechanical stirring and mixing to prepare the multifunctional biological seed coating agent of the present invention.

[0040] Next, 25 parts by weight of cotton seeds are mixed with one part by weight of the multifunctional biological seed coating agent of the present invention, and air-dried outdoors to prepare cotton seeds coated with the multifunctional biological seed coating agent.

preparation Embodiment 2

[0042] In a 30-liter reactor, heat and stir 0.36 kilograms of polyvinyl alcohol and 0.18 kilograms of sodium carboxymethylcellulose in 12 liters of water, then add 0.2 liters of 9% Na-bentonite aqueous dispersion, and mechanically stir to prepare the compound Film suspension in water. The resulting film-forming agent aqueous suspension and 6 liters of salt-dissolving growth-promoting bacteria and combination growth-promoting growth-controlling bacteria fermented liquid (about 10 12 cfu / ml) in a reactor with mechanical stirring and mixing to prepare the multifunctional biological seed coating agent of the present invention.

[0043] Next, 30 parts by weight of cotton seeds are mixed with one part by weight of the multifunctional biological seed coating agent of the present invention, and air-dried outdoors to prepare cotton seeds coated with the multifunctional biological seed coating agent.

preparation Embodiment 3

[0045] In a 30-liter reactor, heat and stir 0.36 kilograms of polyvinyl alcohol and 0.18 kilograms of sodium carboxymethylcellulose in 12 liters of water, then add 0.2 liters of 9% Na-bentonite aqueous dispersion, and mechanically stir to prepare the compound Film suspension in water. The resulting film-forming agent aqueous suspension and 6 liters of salt-dissolving growth-promoting bacteria and combination growth-promoting growth-controlling bacteria fermented liquid (about 10 12 cfu / m1) was mechanically stirred and mixed in the reactor, and finally 0.144 kg of sodium lignosulfonate was added to prepare the multifunctional biological seed coating agent of the present invention.

[0046] Next, 30 parts by weight of cotton seeds are mixed with one part by weight of the multifunctional biological seed coating agent of the present invention, and air-dried outdoors to prepare cotton seeds coated with the multifunctional biological seed coating agent.

Abstract

The invention relates to a multifunctional biological seed coating agent and a preparation method thereof. The multifunctional biological seed coating agent comprises auxiliary agents and beneficial microorganism, volume ratio thereof is 1:1-5, and effective bacterium content is not less than or equal to 10<8>cfu/ml. The auxiliary agent comprises one or various auxiliary agents in film former, dispersant, adhesion agent, protectant, nutritient, anti-freeze agent, preservative and colourant. The beneficial microorganism is selected from one or various rhizobium, azotobacter, pseudomonad, bacillus, K pneumoniae, Enterobacter cloacae and Raoulterlla planticola. The preparation method comprises the following steps: dissolving the polyvinyl alcohol and natural substance with water in a reaction kettle, mixing with the water dispersion liquid of the adhesion agent to prepare a film forming agent, and finally mixing and stirring mechanically with the beneficial microorganism fermentation liquor to obtain the finished product. The invention has the advantages of no residue, high efficiency, low toxicity, strong specificity, good film forming effect and convenient application, therefore, the multifunctional biological seed coating agent plays an significant role of preventing and controlling cotton seedling diseases as well as enhancing the cotton seedling growth under salt stress.

Description

technical field [0001] The present invention relates to the development of a multifunctional biological seed coating agent, more specifically, it relates to a kind of biological seed coating agent which contains beneficial microorganisms as active ingredients, plus film-forming agents and other various auxiliary agents, and has been developed to promote plant growth. The seed coating agent relates to a method for preparing the multifunctional biological seed coating agent. Background technique [0002] Most of the seed coating agents at home and abroad use pesticides and fertilizers as raw materials. After chemical treatment, they achieve the purpose of bonding with the seeds. And utilize microorganism as main raw material to add various auxiliary agents to prepare a kind of water-suspension type seed coating agent, through using DIALOG international on-line retrieval, seldom report. Seed coatings generally consist of active and inactive ingredients. The active ingredients...
