Embodiment 1

[0026] A flavonoid anti-insect and antibacterial humic acid selenium fertilizer has the following raw material components and dosage: sodium humate, natural ginkgo flavonoids and sodium selenite, and the addition ratio in parts by mass is 1:0.15:0.10.

[0027] The preparation process of the flavonoid insect-proof and antibacterial humic acid selenium fertilizer:

[0028] 1) Wash, dry and crush the natural plant Ginkgo biloba, soak in petroleum ether for 12 hours, ultrasonically treat for 30 minutes, vacuum-dry at 40°C after suction filtration, remove pigment and lipid components; press 1g of the treated plant : The solid-liquid ratio of 10ml uses acetone to extract 3h under the ultrasonic wave at 30 ℃, suction filtration obtains the extraction filtrate, controls the adsorption flow rate to be 4 times / h resin column volume with the filtrate of 10 times of column volume and is adsorbed with macroporous adsorption resin, adsorption After complete, wash with 20% absolute ethanol, ...

Embodiment 2

[0034] A flavonoid anti-insect and antibacterial humic acid selenium fertilizer has the following raw material components and dosage: sodium humate, natural baicalin flavonoids and sodium selenate, and the addition ratio in parts by mass is 1:0.25:0.12.

[0035] The preparation process of the flavonoid insect-proof and antibacterial humic acid selenium fertilizer:

[0036] 1) Wash, dry and crush the natural plant Scutellaria baicalensis, soak in petroleum ether for 12 hours, ultrasonically treat for 30 minutes, vacuum-dry at 60°C after suction filtration, remove pigment and lipid components; press 1g of the treated plant : the solid-liquid ratio of 20ml is assisted by ultrasonic extraction of ethanol at 40 ℃ for 2.5h, and the extraction filtrate is obtained by suction filtration, and the adsorption flow rate is controlled to be 4 times / h with the filtrate of 10 times of column volume. After the adsorption is complete, wash with 20% absolute ethanol, then desorb with 90% ethano...

Embodiment 3

[0042] A kind of flavonoid anti-insect and antibacterial humic acid selenium fertilizer, its raw material components and dosage are as follows:

[0043] Potassium humate, natural kudzu root flavonoids and selenomethionine are added in a ratio of 1:0.2:0.15 in parts by mass.

[0044] The preparation process of the flavonoid insect-proof and antibacterial humic acid selenium fertilizer:

[0045] 1) Wash, dry and pulverize the natural plant kudzu root, soak in petroleum ether for 12 hours, ultrasonically treat for 30 minutes, and vacuum-dry at 45°C after suction filtration to remove pigment and lipid components; press 1g of the treated plant : The solid-liquid ratio of 30ml uses n-butanol to extract 2.5h under the ultrasonic wave at 60 ℃, suction filtration obtains the extraction filtrate, and the filtrate control adsorption flow rate is 4 times / h resin column volume with macroporous adsorption resin with the filtrate of 10 times column volume Adsorption, after the adsorption is...

Abstract

The invention discloses flavonoid insect-proof antibacterial humic acid selenium fertilizer and a preparation method thereof, and relates to the field of agricultural fertilizer application. The flavonoid insect-proof antibacterial humic acid selenium fertilizer is prepared from 1 part of humate, 0.01 to 0.4 part of natural plant flavonoid substances and 0.01 to 0.2 part of selenium-containing compounds, the preparation method comprises the following steps: 1) weighing the low-rank coal-based humate, the natural plant flavonoid substance and the selenium-containing compound in proportion, 2) preparing low-rank coal-based humate into a solution with the concentration of 2%-10%, 3) adding natural plant flavonoid substances into the low-rank coal-based humate solution obtained in the step 2),and stirring to obtain a mixed solution of humate and flavonoid substances, and 4) adding a selenium-containing compound into the mixed solution obtained in the step 3), controlling the temperature at 30-60 DEG C, and mixing and stirring to obtain the flavonoid insect-proof antibacterial humic acid selenium fertilizer. The compound fertilizer prepared by the method is environment-friendly and hasthe properties of repairing and improving soil, preventing insects and bacteria and improving crop quality.

Description

technical field [0001] The invention belongs to the application field of agricultural chemical fertilizers, and in particular relates to a flavonoid insect-proof and antibacterial humic acid selenium fertilizer and a preparation method thereof. Background technique [0002] Humic acid exists in a large amount in nature, its structure is relatively complex, and its molecular chain has a variety of active functional groups, which can interact with many inorganic and organic compounds, and can improve the physical and chemical properties of soil and enhance fertilizer efficiency. Flavonoids are a class of natural products that widely exist in plants. They play an important role in plant growth and development, flowering and fruiting, and prevention of bacteria and diseases, and have great medicinal value. Selenium is an essential trace element for the human body. Selenium deficiency will seriously endanger human health. Due to the special role of selenium and the current situat...
