Description

Technical Field

[0001] The invention relates to the technical field of agricultural planting, and in particular to a grass-proof cloth. Background Art

[0002] The large number of weeds growing in the orchard will not only compete with the fruit trees in the orchard for nutrients, affecting the amount of fruit and the fullness of the fruit trees, but also make it difficult to prune and pick the fruit trees. At present, horticultural grass-proof cloth has become a commonly used covering material for orchard weed prevention. It has a good inhibitory effect on weeds under the trees, and can also conserve moisture and increase temperature. In recent years, its application in orchards has increased. However, in actual applications, due to the transparent structure of the grass-proof cloth, it is difficult to prevent weeds from photosynthesizing, and its role in preventing weed growth is limited. The grass-proof cloth has poor air permeability and weak water infiltration capacity, which not only affects the water absorption of the plants, but also affects the root system and soil ecology of the fruit trees due to its long-term laying. Especially in the high temperature of summer, it is easy to produce very high ground temperature, which seriously affects the normal growth and development of the root system and causes damage to the tree.

[0003] To this end, the present invention increases the air permeability and water permeability of the ground cloth by folding and punching the ground cloth, and utilizes the staggered transparent holes to prevent weeds from growing outwards. Summary of the invention

[0004] The purpose of the present invention is to solve the defects in the prior art and to provide a grass-proof cloth.
