 Non-woven fabrics are the main application areas in agriculture

First, covering materials

Europe in spring and autumn has a complicated climate.Plants in the glass conservatory may die from frost that affects their growth.The traditional solution is to use "floating cap technology".It is to spread the light and transparent covering material directly on the plants to provide effective, inexpensive and temporary climate protection.Prevent frost and allow plants to grow as usual

Non-woven fabric has light transmission.Transparency and permeability to air and water make it an ideal covering material for plants.Use of non woven, it a 25 grams is 8 g/m ', they can make the ground temperature and plant temperature increased 2 a 4 ℃.This protects the crop from spring and autumn frost (porous polyethylene films have been used before).

Compared with polyethylene film (plastic), agricultural non-woven fabric has the following advantages.

1) good permeability to water and chemical treatment agents

2) good anti-infrared radiation, ensure the warm spring period is suitable for ventilation, so as to reduce the risk of "heatstroke" ("heatstroke", is because the temperature is too high so that the shoot leaves are burnt, dead, and ultimately affect the quality and yield of vegetables.)

3) due to the special structure of agricultural non woven, the uniform infiltration of wind is improved.

4) to protect people from parasites such as insects.

Ventilation, thereby reducing the risk of "heatstroke" (" sunstroke "), is due to the temperature is too high and so that the tip leaves are burnt, dead, and ultimately affect the quality and yield of vegetables.

Second, the heat insulation

Non-woven fabrics can be used in glass greenhouses to replace other materials used for heat insulation. They can also be coated with aluminum to enhance their reflectivity. Non-woven fabrics for this purpose have the following advantages.

1) can be folded, small space, to prevent the loss of light in the greenhouse.

2) because of its permeability, can prevent damage to crop growth of the "condensation" effect.

3) due to the special structure of agricultural non woven, the uniform infiltration of wind is improved.

4) to protect people from parasites such as insects.

Three, shading

Non - woven fabric can be used as a light - shading screen for various plants.Non-woven fabrics of different grams and colors can be selected according to the different characteristics of plants.For example, in the United States, usually use black non-woven fabric as a nursery screen;Europe USES green non woven to shade leafy vegetables, while Japan USES gray to shade ginseng.

Finally, terilization and insect control

In northern Europe and the United States, these countries have strict restrictions on the use of vegetable pesticides, so.Non-woven fabric is chemically treated and covered on vegetables, which not only kills insects and disinfects bacteria, but also prevents different predators (animals and birds) and parasites (flies, insects with viruses, etc.) from damaging crops, and also prevents vegetables and the surrounding environment from being polluted by pesticides.

All kinds of farm bags

To protect the fruit from insects when it is ripe, it is of high quality.High value fruit, using the air permeability of non woven fabric, can replace paper to make fruit protective bags.They can also be used for pollination, rooting or other agricultural purposes.

Seed matrix

In the aspect of rice growth and slope greening, non-woven fabric can be used as seed matrix.To be specific, seeds are sown on non-woven fabric materials in advance, and various fertilizers, insecticides and other feed stocks directly provided to seeds or seedlings are added.One of the non - woven as long as the simple flat on the ground.This 

technique not only increases the germination rate of seeds and improves the growth of seedlings, but also simplifies the sowing operation and procedure and reduces the labor intensity.

Seven, irrigation cloth

In the pure nutrient solution culture method, non-woven cloth is used as an extremely thin layer of irrigation cloth to improve the distribution of nutrient solution.Also can use thicker sheet material to make growth matrix, put flowerpot or container on its,  make water gets even and distributive.

Viii. Covering materials

In many cases, plants are grown in containers and the ground must be covered with black non woven cloth to prevent weeds from growing.It has water resistance and permeability, so can discharge any excess water.In the United States, bonsai gardeners take advantage of non woven fabrics.Replace pine bark to make bonsai cover material, in order to ensure the aesthetic characteristics of green space.
