AgriculturalAnti Grass Cloth, also known as farm weed isolation mat, is a fabric or membrane made of high-strength materials, mainly laid on the soil surface to prevent weed growth, keep the soil moist, and optimize the crop growth environment.
Physical methods (shading, isolation) block the sunlight required for weed seeds to germinate, while allowing air and water to pass through, thereby suppressing weeds while ensuring that crops absorb water and nutrients normally.
Anti Grass Cloth usually consists of the following parts:
Main material layer: Made of polymer materials such as polypropylene (PP) or polyester (PET), giving the weed control cloth good mechanical strength and durability.
Woven or non-woven structure: According to different manufacturing processes, it is divided into woven structure (warp and weft interweaving) and non-woven structure (hot pressing or needle punching).
Ultraviolet stabilizer (UV treatment): Add special stabilizers to improve the anti-ultraviolet performance of weed control cloth and extend its outdoor service life.
Water-permeable and breathable pores: Reasonably control the porosity to allow water to penetrate and air to circulate to prevent soil compaction.
Classification of agricultural weed control fabrics
According to different manufacturing processes and structures, agricultural weed control fabrics are mainly divided into three categories:
Woven Weed Control Fabric
Woven with PP flat wire, presenting a lattice structure;
Features: high tensile strength, uniform air permeability and water permeability, and wear resistance;
Commonly used in orchards, vineyards, vegetable bases and other places where long-term weed control is required.
Non-woven Weed Control Fabric
Made by short fiber hot bonding, needle punching and other processes;
Features: soft to the touch, easy to construct, suitable for temporary or short-term projects;
Commonly used in flower nurseries, horticultural projects, etc.
Choose according to crop type
Different crops have different performance requirements for weed control cloth. When choosing, you should fully consider:
Orchard crops (such as apples, grapes, and citrus)
Choose thick woven weed control cloth with a gram weight of about **100-150g/㎡**;
Requires good water permeability and air permeability to prevent water accumulation at the roots;
Color recommendation: black or black and green, which can prevent weeds without affecting the ventilation of the lower part of the fruit tree.
Vegetables (such as tomatoes, cucumbers, and peppers)
It is recommended to use medium-weight weed control cloth, about 80-120g/㎡;
Ensure good air permeability and facilitate transplanting and punching holes;
The color can be green or black. Green cloth can reduce the ground temperature in hot areas.
Flowers and nursery crops
It is recommended to use highly permeable non-woven weed control cloth;
Requires light and thin, convenient for temporary laying and movement;
The color can be black, which is more effective in suppressing weeds.
Specification selection tips
The selection of specifications for weed control cloth should be based on the specific use area and construction convenience.
Gram weight (g/㎡): Generally, it is selected within the range of 70-150g/㎡. The higher the gram weight, the thicker the weed control cloth and the stronger its durability.
Width: Common widths are 1 meter, 2 meters, 3 meters, 4 meters, or even wider. When choosing, crop row spacing and laying convenience should be considered.
Length: Conventional rolls are 50 meters and 100 meters, which can also be customized to reduce splicing and improve construction efficiency.
Common problems and solutions in the use of agricultural weed control cloth
Damage and tearing of grass-proof cloth
Problem analysis
Pulling too hard or improper tool operation during laying;
Sharp objects (such as stones and tree roots) on the ground cause wear and tear;
External damage such as strong winds, heavy rains, and animal bites;
Using low-quality grass-proof cloth with insufficient tensile strength.
Solution
Clean up the debris on the ground thoroughly before laying to ensure flatness;
Avoid pulling hard during construction, and lay it gently and slowly;
Select high-quality grass-proof cloth with strong tear resistance (≥100g/㎡);
When a small area is damaged, use special grass-proof cloth repair tape to paste;
When a large area is damaged, the local cloth should be replaced in time and the ground nails should be strengthened to fix it.
Weeds grow from the seams and edges of the cloth
Problem analysis
The overlap of the weed-proof cloth is too small, leaving gaps for weeds to grow;
The number of ground nails is insufficient, and the edges are loose;
Weed seeds fall on the surface of the weed-proof cloth and take root.
Solution
When laying, the overlap width should be at least 20cm, and compacted and fixed along the gap;
The density of ground nails is increased, and it is generally recommended to have at least 2-3 ground nails per square meter;
Regularly clean the mud and floating seeds on the surface of the weed-proof cloth to reduce the growth of weeds on the surface;
For serious areas, a small amount of sawdust can be spread or mulch can be laid to enhance the weed suppression effect.
