Problems solved by technology

[0004] At present, most of the existing orchards, such as vineyards, use bio-control Trichoderma fungal agents for simple whole-garden spraying. Due to the influence of unfavorable factors such as oligotrophic environment in the epiphytic environment on the plant surface, unstable temperature and humidity conditions, and high ultraviolet intensity, it is difficult to Let the bio-control bacteria obtain the environmental conditions that can stabilize the colonization and proliferation, so that when the bio-control bacteria are used, there are problems such as short drug effect period, large amount of use, high frequency of use, and poor effect of improving the ecological status of microorganisms in the orchard.

Embodiment 1

[0023] A method for improving the application effect of trichoderma in orchards, wherein said orchards are specifically vineyards, comprising the following steps:

[0024] (1) Mix the commercially available "Yingcaimeidi" brand green Trichoderma fungus agent with water according to the concentration and dosage in the product instructions, and then add γ-polyglutamic acid (final concentration 300mg / L) and molasses alcoholic fermentation broth (final Baume degree value is 2°Be), obtain suspension after mixing;

[0025] (2) the suspension prepared in step (1) is evenly sprayed on the grape branches, especially the position covered by old skin;

[0026] (3) when the suspension is still not dry, immediately spray chitosan borate solution (the chitosan borate solution is that 1g of chitosan with deacetylation degree 85% is dissolved in 100mL concentration is 5g / L boric acid aqueous solution); make chitosan borate and γ-polyglutamic acid polymerized to form a selective antibacteria...

Embodiment 2

[0028] A method for improving the application effect of trichoderma in orchards, wherein said orchards are specifically vineyards, comprising the following steps:

[0029] (1) Fully mix the commercially available Trichoderma harzianum inoculum agent of Byward Company with clear water according to the concentration and dosage of the commodity instructions, add γ-polyglutamic acid (final concentration 1000mg / L) and sugarcane waste molasses (final Baumé degree value is 0.5°Be).

[0030] (2) Spray the above-mentioned suspension evenly on the grape branches, especially the parts covered by old skins.

[0031] (3) When the above-mentioned suspension was not yet dry, the chitosan borate solution immediately sprayed [1g of chitosan with a deacetylation degree of 80% was dissolved in 100mL concentration of 8g / L boric acid aqueous solution, diluted with water to 2 times the volume] to polymerize chitosan borate and γ-polyglutamic acid to form a selective antibacterial film on the outer...

Embodiment 3

[0033] A method for improving the application effect of trichoderma in orchards, wherein said orchards are specifically vineyards, comprising the following steps:

[0034] (1) Fully mix the Trichoderma longibrachiae agent purchased from the China Agricultural Microorganism Culture Collection Center with water according to the concentration and dosage of the product instructions, add γ-polyglutamic acid (final concentration 500mg / L) and molasses for alcoholic fermentation liquid (the final Baume value is 5°Be).

[0035] (2) Spray the above-mentioned suspension evenly on the grape branches, especially the parts covered by old skins.

[0036] (3) when above-mentioned suspension liquid is not dry yet, spraying concentration immediately is chitosan borate solution [dissolving the chitosan of 1g deacetylation degree more than 75% in the boric acid aqueous solution of 10g / L in 100mL concentration, Prepared by diluting with water to 10 times the volume] to polymerize chitosan borate ...

Abstract

The invention provides a method for improving the application effect of orchard trichoderma, belonging to the technical field of fruit tree maintenance. The invention comprises the following steps: (1) fully mixing the Trichoderma inoculum with clear water, adding γ-polyglutamic acid and sugarcane waste molasses or molasses alcoholic fermentation liquid to obtain a suspension; (2) preparing The obtained suspension is evenly sprayed on the branches of fruit trees; (3) when the suspension is not dry, immediately spray the chitosan borate solution to make the chitosan borate and γ-polyglutamic acid polymerized , to form an antibacterial film on the outer layer. The method of the present invention can improve the ability of bacteria agent to attach and colonize on the epidermis of tree branches, improve the sporulation and antagonistic ability of the bacteria agent, and then improve the ability of the bacteria agent to proliferate in the orchard, and improve the effect of improving the ecological status of microorganisms; The ability of the fungicide to decompose the old bark of the grape vine promotes the shedding of the old bark and reduces the hiding space for diseases and insect pests.

Description

technical field [0001] The invention belongs to the technical field of fruit tree maintenance, and in particular relates to a method for improving the application effect of orchard trichoderma. Background technique [0002] With the development of society, people are increasingly aware that the use of chemical pesticides is at the expense of the ecological environment and human health, while biological control with the purpose of sustainable agricultural development plays an increasingly important role in agricultural production . Biological control is a method of using beneficial organisms or their metabolites to prevent and control harmful organisms. Its advantages are that it is safe for humans and animals, has no residual toxicity, does not pollute the environment and fruits, does not produce resistance to harmful organisms, does not destroy the ecological balance, and is economical and effective. [0003] According to reports, Trichoderma is one of the most commonly us...
