The grass-proof cloth laid in the orchard is a black woven cloth that is both abrasion-resistant and anti-aging, and is woven from UV-resistant polypropylene flat yarn.
Mainly used for ground moisture-proof, drainage, keeping the ground clean, ground marking and guidance.
The advantages of grass cloth are:
1. It has various physiological and ecological effects such as environmental protection, ventilation and water permeability, temperature increase, moisture preservation, no-tillage, fertilizer increase, control and reduction of pests and diseases.
2. Inhibit the growth of weeds, cover with black weed-proof cloth, because the weeds cannot see light after germination, the photosynthesis is inhibited and will die, and the effect is very good.
3. Increase the ground temperature: After covering the grass-proof cloth, the black color can absorb sunlight and block the soil heat from radiating outward, which can increase the ground temperature by 3-4°C.
4. Keep the soil moist: After covering the grass-proof cloth, it can inhibit the evaporation of water, maintain a certain soil humidity, and reduce the number of watering.
5. Improve soil aggregate structure and nutrition: after covering with grass-proof cloth, due to ventilation, soil microorganisms increase, soil is loose, and there is no compaction phenomenon, and at the same time, soil nutrient content can be increased.
6. Conserve fertilizer, use grass-proof cloth to increase fertilizer utilization rate, increase production and income, and reduce pests and diseases.
The main methods of using the weed-proof cloth:
The laying of the grass-proof cloth is very simple, as long as the ground is compacted first (if the grass-proof cloth has better water permeability and air permeability, a coarse sand layer of about 10cm can be laid under the grass-proof cloth), and then the finished grass-proof cloth is pressed according to the requirements. After the laying direction is spread out and flattened, insert the “Ω” type into the ground at a certain distance between the joints. The lap length should not be less than 10 cm (indoor) or 20 cm (outdoor), and then fix it with iron nails to complete the laying. .
What problems should be paid attention to when choosing grass-proof cloth:
Some problems that customers should pay attention to before purchasing grass-proof cloth mainly include fire protection and high temperature resistance of grass-proof cloth. Gardening ground cloth is a plastic product, which is very prone to fire. During the period from late autumn to early spring, due to the dry climate and dry weeds, it is strictly forbidden to set fire to the orchard and its surroundings. In particular, more attention should be paid to orchards covered with grass and grass.
From May to August, due to the high outside temperature, if the ground cloth is laid at this time, the air temperature under the ground cloth will rise sharply in a short period of time at noon. Compared with the laying of ground cloth in winter and spring, the tree body in this period has not undergone the process from low temperature to high temperature. During the adaptation process, the bark will be scalded to varying degrees, and the whole apple tree may even die at a young age. Therefore, it is not recommended to lay grass-proof cloth in high temperature seasons.
