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

Embodiment 1

[0059] as image 3 The shown simple greenhouse 30 carries out the field planting test, wherein the material of the non-pesticide physical isolation disease and insect pest transparent polymer film 1 used in the simple greenhouse 30 is PE (polyethylene), and the thickness of the film is 0.1mm, and there are punctures on it. Aperture 4mm, density 40,000 / m 2 (hole distance 5mm), hole diameter 2mm, density 40,000 / m 2 (hole distance 5mm) and hole diameter 1mm, density 20,000 / m 2 (hole distance 5mm). The selected plant is Chinese cabbage, which is planted in a common field planting method. It takes about 30 to 40 days to harvest from the seed to the adult plant, and it is divided into a control group and an experimental group, wherein the control group That is, no pesticides were used and the simple greenhouse was not used for biological control; the experimental group was no pesticides used but the simple greenhouse 3 was used for biological control.

Embodiment 2

[0064] same as image 3 The shown simple greenhouse 30 is used for field plant planting tests, but when the planting test is carried out, an isolation film for preventing and controlling soil diseases and insect pests is laid on the soil surface of the simple greenhouse 30, wherein the material of the isolation film is also PE (polyethylene), and The thickness of the isolation membrane is 0.1mm, and holes with diameters of 1mm, 2mm, 3mm and 5mm are pierced on it, the hole distance is 7.5mm, and the hole density is 24,000 / m 2 ; The isolation film as shown in Figure 4 and Figure 4b shown, where Figure 4a The hole diameter of the hole 41 in the isolation film 40 is 1 mm, the hole diameter of the hole 42 is 2 mm, the hole diameter of the hole 43 is 3 mm, and the hole diameter of the hole 44 is 5 mm; Figure 4b The hole diameter of the hole 41 in the isolation film 40' is 1mm, the hole diameter of the hole 42 is 2mm, and the hole diameter of the hole 43 is 3mm.

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...
