Fructus forsythia full-effect foliar protective agent and preparation method thereof

Abstract

The invention discloses a fructus forsythia full-effect foliar protective agent and a preparation method thereof, and is characterized in that water and gelatinized starch are mixed according to the ratio of 10:1-15:1 and the protective agent comprises the following substances in percentage by weight: 1%-20% of chitin, 5%-30% of nano activated charcoal, 1%-10% of sodium carboxymethylcellulose, 1%-15% of potassium fulvate, 1%-3% of rare earth nitrate, 1%-3% of soil improvement water-retaining agent, 0.2%-2% of a biological preservative sodium alginate, 0.2%-0.5% of potassium sorbate, 0.03%-1% of an organic silicon penetrating agent, and the balance being a mixed solution of water and gelatinized starch with the ratio of 1-15:1. The foliar protective agent is suitable for the whole period ofthe growth of the fructus forsythia, and the nutrient supplement is from the mixture of starch, gelatin and a small amount of lecithin, the protective agent can be cast into a film, and the capability of adsorbing dust by the fructus forsythia leaves is increased through air flow, so that the occurrence of haze is prevented; a plurality of nutrient elements are added, the protective agent is suitable for protecting leaves in the whole period of the growth of the fructus forsythia; after rain, the fructus forsythia full-effect foliar protective agent can be sprayed again.

Description

technical field [0001] The invention belongs to the technical field of forsythia cultivation, and in particular relates to a forsythia full-effect leaf protectant and a preparation method thereof. Background technique [0002] There are 5,042.4 tons of pollutants suspended in the air. The composition of the haze is very complex, including hundreds of atmospheric chemical particulate matter. Among them, the most harmful to health are aerosol particles with a diameter of less than 10 microns, such as mineral particles, sea salt, and sulfate. , nitrate, organic aerosol particles, fuel and automobile exhaust, etc., which can directly enter and adhere to the human respiratory tract and alveoli; especially submicron particles will be deposited in the upper and lower respiratory tract and alveoli respectively, causing acute rhinitis and Acute bronchitis and other diseases; for patients with chronic respiratory diseases such as bronchial asthma, chronic bronchitis, obstructive emphy...

[0002] There are 5,042.4 tons of pollutants suspended in the air. The composition of the haze is very complex, including hundreds of atmospheric chemical particulate matter. Among them, the most harmful to health are aerosol particles with a diameter of less than 10 microns, such as mineral particles, sea salt, and sulfate. , nitrate, organic aerosol particles, fuel and automobile exhaust, etc., which can directly enter and adhere to the human respiratory tract and alveoli; especially submicron particles will be deposited in the upper and lower respiratory tract and alveoli respectively, causing acute rhinitis and Acute bronchitis and other diseases; for patients with chronic respiratory diseases such as bronchial asthma, chronic bronchitis, obstructive emphysema and chronic obstructive pulmonary disease, haze weather can cause acute attack or acute exacerbation of the disease; if you stay in this environment for a long time It can also induce lung cancer; forsythia leaves are densely planted, and it is an important green plant for wind, dust, dust and haze reduction. It is also an important greening seedling for urban streets. In the past, we have ignored the absorption and adsorption of forsythia on dust. Has great production value and social significance
