First, the application in the greenhouse
  
In the greenhouse, there are mainly three ways to apply the gardening cloth: the whole ground protection, the partial ground protection and the seedbed base.
  
1. overall ground protection
  
The ground full spread of the greenhouse was applied to the soil free cultivation of vegetables and flowers and the pot planting of crops. The ground cloth was laid directly on the ground surface of the greenhouse, and no other ground was needed. The placement of crops can be accurately operated according to the marking lines on the ground cloth. Sometimes, the planter lays a layer of fine sand about 20 millimeters on the surface of the cloth for the purpose of protecting the cloth or increasing the water content of the cloth surface (as shown in Figure 1).
  
2. local ground protection
  
This usage is mainly combined with seedbed to prevent weeds from producing weeds in the lower part of the seedbed. Laying ground cloth in the lower part of the seedbed is one of the most common uses in China's greenhouses, which can also reduce the water accumulation in the lower part of the seedbed (especially under the overall irrigation of the seedbed), so as to regulate the humidity in the greenhouse.
  
3. bed base
  
The ground cloth can also be laid directly on the bed surface of the bed, as the support layer of the bed surface, thus simplifying the support structure of the bed surface and reaching the purpose of suitable for various cultivation containers (such as Figure 2).
  
Two, outdoor application
  
As a kind of material to inhibit weeds and keep the ground clean, the ground cloth has been widely used in the fields of outdoor potted flowers, nursery, large garden beautifying, grape planting and so on. It has become a part of a high standard cultivation model in the United States and Europe. After the use of ground cloth, a large number of ground floor construction costs and construction time can be saved. The base treatment method of the ground cloth can not only maintain the stability of the ground water and soil and floor, but also solve the problems of drainage and weed suppression more conveniently.
  
The ground cloth can also be used to protect the roots of trees. The use of ground cloth near the root of the tree can effectively reduce the growth of root weeds, thus reducing the loss of root nutrition and water. The ground cloth of this kind of use is a lump or strip, with different marking lines on the surface, such as "10 font", "T", "I" as a planting incision. These cutouts should be treated by heat treatment after tree planting, so as to ensure the integrity and function of the cloth.
  
When the tree is transplanting, the root of the tree can be wrapped with ground cloth to reduce the growth of the root weeds, to prevent the ineffective growth of the roots of the trees, to ensure the permeability and permeability of the roots of the trees, and to protect the roots of the trees from the external injury during the process of transportation and temporary storage.
  
Three. Use of attention
  
The lap of 1. material
  
As the ground cloth has a certain width limit, in order to ensure the continuity of the ground cloth in the process of use, there should be a certain lap in the width direction in the laying of the ground cloth. The length of the lap should not be less than 10 centimeters (indoors) or 20 centimeters (outdoor). Indoor lapping can be placed naturally, while outdoor lapping should adopt some additional fixed measures.
  
Construction of 2. laying cushion
  
In order to achieve good permeability, good ventilation, smooth surface and certain surface strength, the laying base of the floor cloth should be treated. Generally, the bottom of the ground cloth should be laid about 10 centimeters of coarse sand layer. Because the coarse sand has the characteristics of solid aggregate structure, large pore and small deformation under external force, it is very suitable for the surface cushion of the ground cloth. The lower part of coarse sand should be treated according to the local soil condition. Generally, if the soil is stronger and the permeability is better, the coarse sand layer can be laid directly on the surface, otherwise the gravel layer or pebble layer of 10 to 15 centimeters should be laid in the lower part of the coarse sand to ensure the water permeability and the strength of the surface of the ground cloth, which is beneficial to the crops.
