Problems solved by technology

The thin film formed by Bordeaux mixture is a layer of insoluble inorganic salt particle film that accumulates irregularly and adheres to the plant surface. The particle activity is small and the film formation rate is low. The film has a single function, is not waterproof, light-proof, difficult to decompose, affects the photosynthesis of plants, and is not conducive to plant growth

Embodiment 1

[0025] First, add 350Kg of water into a 500L reactor, and add 50Kg of hydroxypropyl methylcellulose under stirring to dissolve completely. Then add 300Kg of water into the 1000L reactor, heat it to 70°C, add 30Kg of gelatin under stirring, after it is completely dissolved, add 10Kg of sodium dodecylsulfonate and 100Kg of sodium humate, and add the above 400Kg after cooling Hydroxypropyl methylcellulose aqueous solution, 80Kg polyvinyl acetate emulsion, 20Kg nanometer white carbon black and 60Kg polyoxyethylene lauryl ether, stir 1h, obtain dark brown homogeneous suspension, material pH value 7.6, viscosity (coat-4 cup, 25°C) for 94 seconds, and the product is packaged.

Embodiment 2

[0027] First, add 300Kg of water into a 500L reactor, and add 30Kg of hydroxypropyl methylcellulose under stirring to dissolve completely. Then add 350Kg of water into the 1000L reactor, heat to 80°C, add 20Kg of gelatin under stirring, and after it is completely dissolved, add 10Kg of sodium octylsulfonate and 120Kg of ammonium humate, and then add the above 330Kg of hydroxypropyl Aqueous methyl cellulose solution, 110Kg polyvinyl acetate emulsion, 10Kg nanometer white carbon black and 50Kg polyoxyethylene lauryl ether, stir 1.5h, obtain the uniform suspension of dark brown, material pH value 6.8, viscosity (coat-4 cups , 25°C) for 76 seconds, and the product is packaged.

Embodiment 3

[0029] In order to understand the preventive effect of the film agent of the present invention on apple tree rot, and to provide a scientific basis for popularization and application in the future, the film agent of the present invention was used in 2006 to smear and rot the 13-year-old red Fuji orchard in Zhang Haifang, Beixin Village, Beixin Township, Linyi County. Lesion test, and compared with related chemicals, water as control, the test results are shown in the table below:

[0030] Table 1 plant protective film agent of the present invention prevents and treats fruit tree rot field test summary

[0031]

[0032] As can be seen from Table 1, the plant protective film agent of the present invention has a control effect of 94.15% on apple tree rot, which is obviously higher than other agents. After smearing the film agent of the present invention, the callus grows obviously, and the lesion heals quickly without any adverse effect on the growth and development of the tre...

Abstract

The invention discloses a plant protection pellicle, comprising 8-12 percent of polyvingl acetate emulsion,8-12 percent of humate, 3-5 percent of hydroxypropyl methylcellulose, 0.5-1 percent of alkyl sulphonates, 4-6 percent of Polyoxyethylene lauryl alcohol, 1.5-3 percent of gelatine glue, 1-2 percent of nano silica hydrated and 60-70 percent of water, and the compositions are added into water and mixed evenly to achieve black-brown suspension liquid. The plant protection pellicle has the functions of drug action, fertilizing, bagging and slow release. After dilution by water and spraying, a monomolecular film invisible to eyes is formed on the surface of the plant, thereby, the fruit tree is coated with 'clothes' immediately for thermal insulation, frost protection and drought resistance, restraining the transpiration of the moisture in the tree body, preventing the secondary infection of disease germs and improving the quality of agricultural products.

Description

technical field [0001] The invention belongs to the technical field of plant protection, and in particular relates to a plant protective film agent for spraying on the surface of plants to protect plants and improve plant growth quality. Background technique [0002] With the adjustment of the rural industrial structure, the fruit and vegetable planting area has been able to grow exponentially. Although the spraying of pesticides has solved the problem of infestation by diseases and insect pests to a certain extent, it has brought about the problem of excessive pesticide residues and serious environmental pollution. In recent years, fruit bagging technology has been widely promoted as a measure to solve the harm caused by excessive use of pesticides. Though this technology can reach the purpose of producing pollution-free fruit, there are still many defectives. [0003] The application of film in plant protection is mainly to use the inorganic salt film formed by Bordeaux ...
