Application of grass-proof cloth in agriculture

Weed-proof cloth is a kind of plastic woven cloth woven from UV-resistant polypropylene flat yarns that is resistant to friction and aging. It is also called "weed control cloth" and "weed control cloth" in production. It is mainly used on the ground Weed prevention, drainage, keeping the ground clean, ground marking and guidance, etc. Weed-proof cloth mulching measures have been applied to many fruit trees such as dragon fruit, blueberries, oranges, grapes, etc. The mulching can inhibit the growth of weeds in the orchard, maintain soil moisture, and reduce labor costs.

The following three aspects should be grasped when choosing grass cloth:

Width: The width of the material is related to the laying method and quantity. In order to reduce the time loss and material loss caused by cutting, the standard width of ground cloth should be used as much as possible for plane combination. The current common width is 0.5 to 6 meters. The length can be selected according to the actual situation. The length between 100 meters and 1000 meters is normal.

Color; the ground is available in black, white, and green colors. Black and green are mostly used outdoors, while white is mainly used in greenhouses. Its function is to increase the light level in the greenhouse to promote photosynthesis of plants. At the same time, Because the white ground cloth reflects light on the ground, it can also reduce the heat accumulation on the ground of the greenhouse and lower the ground temperature. At the same time, by reflecting light, it can prevent the survival of unhappy insects behind the fruit tree leaves in the greenhouse and reduce crop diseases. Therefore, white ground cloth is often used in greenhouse cultivation where light requirements are relatively high.

Life span: Since the main function of the weed-proof cloth is ground protection and weed suppression, its service life should have certain requirements, otherwise, the damage of the material will directly affect the drainage, weed suppression and other functions, from the production investment and benefit From the point of view, the material's cost performance (life/price) should be greater than 2, and the service life of general floor coverings can reach more than 3-5 years.

The grass-proof cloth not only saves labor and effort, but also the laying operation is quite simple. When laying, just follow the planting row of the fruit tree, cover the weed-proof cloth on the nutrient belt of the fruit tree (the vertical projection of the canopy), spread it evenly, and finally fix it with plastic ground nails to prevent wind blowing.

1. The characteristics of grass-proof cloth:

1. High strength: Due to the use of PP and PE plastic flat yarns, it can maintain sufficient strength and elongation in dry and wet conditions.

2. Corrosion resistance: long-term corrosion resistance in soil and water with different pH.

3. Good air and water permeability: There are gaps between the flat yarns, so it has good air permeability and water permeability.

4. Good anti-microbial performance: no damage to microorganisms and insects.

5. Convenient construction: Because the material is light and soft, it is convenient to transport, lay and construct.

6. High breaking strength: up to 20KN/m or more, good creep resistance and corrosion resistance.

7. Anti-purple and anti-oxidant: add imported UV and anti-oxidant, it has good anti-purple and anti-oxidation.

2. The function and use of the weed-proof cloth:

1. Prevent weeds on the ground. Because the ground cloth can prevent the direct sunlight on the ground (especially the black ground cloth), and at the same time, the strong structure of the ground cloth itself prevents weeds from passing through the ground cloth, thus ensuring the inhibitory effect of the ground cloth on the growth of weeds.

2. Timely drain the ground water and keep the ground clean. The drainage performance of the ground cloth guarantees the rapid drainage of ground surface water, and the pebble layer and middle sand layer under the ground cloth can effectively inhibit the infiltration of soil particles, thus ensuring the cleanliness of the ground cloth surface.

3. It is beneficial to the growth of plant roots and prevents root rot. This effect is also derived from the woven laying structure of the ground cloth, which can ensure that no water is generated at the roots of the crops, and the air at the roots has a certain fluidity, thereby preventing root rot.

4. Prevent the extra growth of the roots of potted flowers and improve the quality of potted flowers. When producing potted flowers on the ground cloth, the ground cloth can prevent the roots of the crops in the pot from passing through the bottom of the pot and digging into the ground, thereby ensuring the quality of the potted flowers.

5. Conducive to cultivation management: most of the grounds are woven with one-way or two-way marking lines. When placing flower pots or arranging cultivation substrates in the greenhouse or outdoors, you can accurately arrange them according to these marking lines.

With the country's vigorous development of environmental protection work in recent years, and various measures taken, the weeding of agricultural orchards is also facing a new revolution. It is necessary to replace herbicides with new products, and weed-control cloths have emerged. Anti-weed cloth is also called "weed control cloth", "weed control cloth", "grass cloth", "insulation cloth", "moisturizing cloth", "garden ground cloth" and so on. It is made of environmentally friendly polypropylene and self-developed polymer functional materials. It is physically weeded and can be used properly to achieve zero pollution. In addition, the grass-proof cloth is a new type of agricultural grass-weeding cloth that is breathable, water-permeable, moisture-proof and cold-proof, protects moisture and promotes absorption, and effectively prevents the growth of weeds. It has been used by many fruit tree planting bases to cultivate fruit seedlings in greenhouses and outdoor fruit trees for weed control.
