A transparent high-molecule thin film used for physical isolation of plant diseases and pests without pesticides

Abstract

The invention provides a transparent high-molecule thin film used for physical isolation of plant diseases and pests without pesticides. The thin film is a transparent plastic thin film and is 0.03-1.00mm thick. The transparent high-molecule thin film used for physical isolation of plant diseases and pests without pesticides is provided with holes with a diameter of 1mm-30mm and the density of the holes in the thin film is 1,000-200,000 / m<2>. The transparent high-molecule thin film used for physical isolation of plant diseases and pests without pesticides can effectively prevent plant diseases and pests and, without using pesticides, enables plants to grow completely in a state of being free of plant diseases and pests, and is a simple and convenient pesticide-free planting tool. The transparent high-molecule thin film used for physical isolation of plant diseases and pests without pesticides can be used repeatedly and is an auxiliary farming tool convenient to operate and low in cost.

Description

technical field [0001] The invention relates to a transparent polymer film without pesticides for physically isolating diseases and insect pests, in particular to a transparent polymer film for preventing and controlling plant diseases and insect pests without using pesticides. Background technique [0002] In the present stage of agricultural development, in order to maintain high yields and sell beautifully, agricultural crops are often sprayed with pesticides to prevent pests and birds, but the disadvantages of the pesticides used are: 1. Harmful to the sprayers themselves Injury; 2. Cause pesticide residues on plants, which will endanger human health after human consumption; 3. Spraying pesticides will pollute the environment and air; 4. The use of pesticides will cause damage to soil damage. Therefore, organic crops have become the focus of modern agricultural development. [0003] However, in the development of organic agriculture, there are still problems in the fiel...

AI Technical Summary

Problems solved by technology

[0002] In the present stage of agricultural development, in order to maintain high yields and sell beautifully, agricultural crops are often sprayed with pesticides to prevent pests and birds, but the disadvantages of the pesticides used are: 1. Harmful to the sprayers themselves Injury; 2. Cause pesticide residues on plants, which will endanger human health after human consumption; 3. Spraying pesticides will pollute the environment and air; 4. The use of pesticides will cause damage to soil damage

[0003] However, in the development of organic agriculture, there are still problems in the field of biological control, such as: the use of adjusted pepper water, vinegar water or acid water can prevent and control pests, but the types of pests that can be controlled are limited. It is not comprehensive enough to completely and effectively prevent the invasion of pests and diseases; while using black gauze or white gauze to prevent pests and diseases, due to the high cost of the gauze and the poor light transmittance of the gauze, it is often difficult to use gauze for pest control. Resulting in reduced crop yields, and these gauzes cannot be reused because of their insufficient mechanical strength and are easily damaged by external forces (such as: wind or animals)

[0004] Furthermore, greenhouses (large-scale greenhouses, including ventilation equipment) are also built to prevent and control pests and birds, but the construction and maintenance costs of greenhouses are too high for ordinary small farmers to afford. Low and effective countermeasures against pests and diseases
