Soil-covering film, the use of a soil-covering film to protect crops against weeds, and a method for the protection of crops against weeds

摘要

The object of the invention is a soil-covering film (10), the essence of which is it contains an air and moisture-permeable sheet, preferably a nonwoven sheet, containing biodegradable and/or compostable fibre (12) and, optionally, binding material (14), where the binding force between the fibres reversibly weakens due to the effect of moisture. The object of the invention is further the use of the soil-covering film (10) according to the invention for providing protection for crops (20) against weeds (30). The object of the invention is also a method for protecting crops (20) against weeds (30), the essence of which is a soil-covering film (10) containing an air and moisture-permeable sheet, preferably a nonwoven sheet containing biodegradable and/or compostable fibres (12) and, optionally, binding material (14) is provided, where the binding force between the fibres reversibly weakens on the effect of moisture, and during the method: - the soil-covering film (10) is laid out on surface of the soil (40); - the seeds (22) of the crop (20) are placed on the soil-covering film (10); - the soil-covering film (10) is kept moist until the seeds (22) located on the surface grow roots (24) and the roots (24) penetrate the soil-covering film (10).
