Abstract
The present invention relates to a plant foliage protecting agent for eliminating damage by soft body pests, which has the components and the contents by weight percentage of 0.5 to 50 % of rosin, 1 to 40 % of sodium carbonate, 1 to 50 % of copper sulfate and water as the rest. The present invention has a preparation method: heating and boiling the water in a stainless steel container, adding the sodium carbonate according to a mixture ratio, adding a certain amount of rosin according to a mixture ratio after complete dissolution, fully stirring with a glass rod, filtering by nylon yarn after complete dissolution to remove residues, immediately adding a certain amount of copper sulfate according to a mixture ratio, simultaneously stirring with a glass rod quickly for a complete reaction, pouring into a sand mill to sand completely after cooling, adding corresponding auxiliary agents, and preparing a suspending emulsion after sanding for a certain period. The present invention has the advantages of control efficiency to soft body pests, no adverse reaction to crops, no three-waste problem in production process, safe use to crops and no phytotoxicity to crops in a larger concentration range.
Description
Technical Field
The invention relates to the field of plant leaf surface protective agents for preventing mollusks from being harmed, and mainly relates to a preparation method of the plant leaf surface protective agent for preventing mollusks from being harmed.
Background
From the analysis of search materials, no mollusk protective agent for preventing and controlling leaf snails, slugs and the like is reported at home and abroad at present. Due to the adjustment of the rural industrial structure, the area of the barren grass land is continuously increased, and the damage degree of the crop leaf surfaces by mollusks such as snails, slugs and the like is obviously improved. Farmers commonly use toxic pesticides to carry out foliage spraying; the leaf surface is cleaned by a broom for organizing labor force, so that the leaf surface of the crop is damaged. Using the Mida granules with luring ability can only ensure ground mollusks, but has no obvious effect on leaf mollusks.
Disclosure of Invention
The invention aims to provide a preparation method of a plant leaf surface protective agent for avoiding mollusk harm, which is safe and reliable to use for crops.
The invention adopts the technical scheme for solving the technical problem. The preparation method of the plant foliage protectant for preventing mollusk from being harmful comprises the following components in percentage by weight: rosin: 0.5% -50%; sodium carbonate: 1% -40%; copper sulfate: 1% -50%; the rest is: water; heating water in a stainless steel container to boil, adding sodium carbonate according to the above ratio, dissolving completely, adding a certain amount of rosin according to the ratio, stirring completely with a glass rod, and filtering with nylon yarn to remove residue after dissolving completely; then, a certain amount of copper sulfate is added immediately according to the proportion, and a glass rod is used for rapid stirring to ensure that the reaction is complete; cooling, grinding in sand mill, adding assistant, and grinding to obtain the final product.
The technical scheme adopted by the invention for solving the technical problem can be further perfected. The components and contents of the protective agent are preferably (weight percentage): rosin: 0.5% -35%; sodium carbonate: 1% -30%; copper sulfate: 1% -35%; the rest is: and (3) water. The components and contents of the protective agent are preferably (weight percentage): rosin: 0.5% -25%; sodium carbonate: 1% -15%; copper sulfate: 1% -25%; the rest is: and (3) water.
The invention has the beneficial effects that: is synthesized by heating plant solid-rosin, inorganic substance sodium carbonate and copper sulfate, and has no by-product. The generated inorganic salt sodium sulfate has control effect on mollusks (snails, slugs and the like), has no adverse reaction on crops, and has no three-waste problem in the production process. Is safe for crops and does not cause phytotoxicity to crops in a larger concentration range. The product of the invention is prepared by using a plant and inorganic salt composition, namely rosin ester copper, wherein the copper is free copper and is dissolved in water (atomic absorption spectrum analysis is carried out on the product of the invention by two different analysis methods of water solubility and nitric acid digestion, so that the copper ion content is not different), so that the product of the invention has no residue on crops and is a good helper for green agricultural products. The invention is a biological low-toxicity protective agent synthesized by plants and inorganic matters, and has abundant raw materials and convenient sources. No pollutant is formed in the synthesis process. After the product of the invention is used, the toxic protective agent is greatly saved, the imported protective agent is reduced, and favorable conditions are created for pollution-free agriculture.
Detailed Description
The present invention will be further described with reference to the following examples.
Example 1: the preparation method of the plant foliage protectant for preventing mollusk from being harmful comprises the following components in percentage by weight: rosin: 200 g of sodium carbonate, 200 g of copper sulfate and 3000 g of water; firstly, heating water in a stainless steel container to boil, adding sodium carbonate according to a ratio, adding a certain amount of rosin according to the ratio after fully dissolving, fully stirring by using a glass rod, and filtering by using nylon yarn after fully dissolving to remove residues; then, a certain amount of copper sulfate is added immediately according to the proportion, and a glass rod is used for rapid stirring to ensure that the reaction is complete; cooling, grinding in sand mill, adding assistant, and grinding to obtain the final product.
The synthesis reaction formula is as follows:
(1)、
(2)、
example 2: the difference from the embodiment 1 is that the preparation method of the plant leaf surface protective agent for avoiding mollusk harm comprises the following components by weight percent: rosin: 300 g, 300 g of sodium carbonate, 300 g of copper sulfate and 3000 g of water.
Example 3: the difference from the embodiment 1 is that the preparation method of the plant leaf surface protective agent for avoiding mollusk harm comprises the following components by weight percent: rosin: 400 g, 300 g of sodium carbonate, 400 g of copper sulfate and 3000 g of water.
Claims (3)
