Application of grass-proof cloth in production

The application of grass-proof cloth in production 　　1. Application in greenhouse 　　 Inside the greenhouse, there are three main application methods of agricultural grass-proof cloth: overall ground protection, partial ground protection, and seedbed base. 1. The overall ground protection 　　 adopts the greenhouse floor covering method, which is used for soilless cultivation of vegetables and flowers, and potted crops. Fruit tree grass cloth prevents weeds on the ground. Because the ground cloth can block the direct sunlight on the ground (especially the black ground cloth), and at the same time use the stable structure of the ground cloth itself to prevent weeds from passing through the ground cloth, and then ensure that the ground cloth can restrain the growth of weeds. Good air permeability, fast water seepage, prevent germs, prevent weed growth, and prevent plant roots from tapping out of the ground. The fruit tree weed-proof cloth is woven from black and green plastic flat yarns with anti-ultraviolet functions that are interlaced with canine teeth. It can effectively block the weeds under the weeding cloth from being exposed to sunlight and prevent the weeds from undergoing photosynthesis. To prevent the growth of weeds; the stable structure of the weeding cloth prevents the roots of plants from burrowing out of the ground, protects the roots of plants, and prevents insects and small animals from harming plants. 2. Partial ground protection 　　 is mainly used in conjunction with the seedbed to prevent weeds from producing diseases in the lower part of the seedbed. Laying ground cloth under the seedbed is one of the common usages in greenhouses in my country. This method can also reduce the accumulation of water in the lower part of the seedbed (especially when the seedbed is irrigated as a whole), thereby regulating the humidity in the greenhouse .　　3. The seedbed base layer 　　 ground cloth can also be directly laid on the seedbed bed surface as a support layer of the bed surface, thereby simplifying the supporting structure of the bed surface and achieving the purpose of being suitable for various cultivation containers. 2. Outdoor application. As a material to suppress weeds and keep the ground clean and tidy, it has been widely used in outdoor potted flowers, nurseries, large-scale garden landscaping, grape planting and other fields. The use of grass-proof cloth can save a lot of The construction cost and construction time of the floor, combined with the grassroots treatment method of the ground cloth, can not only maintain the stability of the ground water, soil and the floor, but also solve the problems of drainage and weed control more conveniently.　　 Weeding cloth can also be used to protect the roots of trees. Using ground cloth near the roots of trees can effectively reduce the growth of root weeds, thereby reducing the loss of nutrients and water in the root zone. The ground cloth for this purpose is in block or strip shape, and marking lines are set on the surface as planting incisions. These cuts must be heat-sealed after the trees are planted to ensure the integrity and function of the ground cloth.
