Spring is here, and grasses emerge from the soil, bringing a vibrant scene to people. However, the growth of grass has also brought troubles to people, affecting the absorption of nutrients by various crops, thereby affecting the yield, and the income of fruit farmers has not reached expectations. In order to solve the troubles of fruit growers, Sugrand has developed and produced a ground cover to control weed, which achieves the effects of good air permeability, fast water seepage, preventing weeds from growing, and preventing roots from drilling out of the ground.
First, let's briefly introduce the weed mat It includes a number of black plastic woven fabrics woven vertically and horizontally to prevent sunlight from shining through the ground cover to the weeds below, preventing the weeds from photosynthesis and preventing weeds. The role of growth, while being able to resist ultraviolet rays and mildew, has certain strength and abrasion resistance, which can prevent plant roots from burrowing out of the ground, beautify the environment, improve labor efficiency and economic benefits, prevent environmental pollution, and reduce agricultural use , It can also prevent the invasion and growth of insects and small animals.
1. The characteristics of weed mat
High strength. Due to the use of plastic flat wire, it can maintain sufficient strength and elongation in wet and dry conditions.
Corrosion resistance, long-term corrosion resistance in soil and water with different pH.
Good water permeability, there are gaps between the flat yarns, so it has good water permeability.
Good antimicrobial properties, no damage to microorganisms and insects.
The construction is convenient. Because the material is light and soft, it is convenient to transport, lay and construct.
High breaking strength, up to 20KN/m or more, good creep resistance and corrosion resistance.
2. The cost-saving advantage of weed mat
Some fruit growers think that the weeds are much longer, just spray more pesticides, but spraying pesticides is not only harmful to the crops, but also harmful to the human body. The cost of labor and pesticides is also high, but the use of ground cover can save one investment. The various costs of about 3 years also protect the environment and the fruit farmers themselves.
3. Precautions for the use of weed mat
Since the ground cover has a certain width limit, in order to ensure the continuity of the ground cloth in use, there must be a certain overlap in the width direction during the laying of the ground cloth, and the overlap length should not be less than 10 cm (indoor) or 20 cm (outdoor). For indoor laps, they can be placed naturally, while for outdoor laps, some additional fixing measures are better.
Construction of laying cushion
A. In order to make the ground cover achieve good water permeability, good air permeability, a smooth surface and a certain surface strength, the laying base of the ground cloth should be treated. Under normal circumstances, a coarse sand layer of about 10 cm should be laid on the lower part of the ground cloth. Because the coarse sand has the characteristics of strong aggregate structure, large pores, and small deformation under the action of external force, it is very suitable as the surface cushion of the ground cloth. For the lower part of coarse sand, the treatment method should be determined according to the local soil conditions. Under normal circumstances, if the soil is firmer and has good water permeability, a coarse sand layer can be laid directly on the surface. Otherwise, a 10 to 15 cm gravel or pebble layer should be laid under the coarse sand to ensure the permeable effect of the ground cloth base layer. And the strength of the surface of the grass-proof cloth, which is conducive to the placement of crops and the walking of workers.
B. The greenhouse floor is fully paved, and it is applied to the soilless cultivation of vegetables and flowers, crop potting, etc. The greenhouse floor is directly laid with ground cloth, and no additional ground is required. The crop placement can be accurately operated according to the marking line on the ground cloth. Sometimes, in order to protect the ground cloth or increase the amount of water attached to the ground cloth surface, the grower also lays a layer of about 20 mm of fine sand on the ground cover mat surface.
4. Application of Weed Mat
The weed mat can be used in vegetable greenhouses and planting flowers to prevent the growth of weeds. It does not use harmful pesticides such as herbicides to truly produce green food. At the same time, the product can be recycled to achieve the purpose of waste reduction and environmental protection.
