[0014] The beneficial effects of the present application are: the present application obtains a barrier water-retaining bentonite pad through the above design. When in use, the non-woven fabric, bentonite and the bentonite pad body of the non-woven fabric structure have little impact on plant production, and the plant roots can more easily penetrate the bentonite pad body. The bentonite pad body can also be coated with bentonite paste on the non-woven fabric. The surface of the non-woven fabric is relatively rough and has many pores inside. The bentonite paste can penetrate into the inside of the non-woven fabric and stick to the surface of the fabric. If the anti-seepage and water-retaining effect of a single layer of non-woven fabric coated with bentonite paste cannot meet the requirements, multiple layers of non-woven fabric coated with bentonite paste can be laid. In addition, the bentonite pad body can choose to use a degradable bentonite pad. The main body and the carrier cloth material are one or more degradable materials such as cotton cloth, linen cloth, viscose cloth, etc. The cover cloth is degradable viscose fiber non-woven geotextile, linen fiber non-woven fabric, cotton and linen non-woven fabric or other degradable non-woven fabric. Bentonite generally uses sodium-based bentonite. If the anti-seepage requirements are not high, calcium-based bentonite can also be used. The degradable bentonite blanket composed of carrier cloth, bentonite and cover cloth is formed into a whole through a needle-punching process. The degradable bentonite mat body can also be prepared by applying bentonite paste on the degradable carrier cloth, degradable cover cloth and other cloths with relatively rough surfaces. The cloth surface is relatively rough, and a certain amount of bentonite paste can be adhered to the cloth. The thickness of the single-layer linen net coated with bentonite paste is Limited. If the requirements for anti-seepage and water retention effects are high, multiple layers of geotextiles coated with bentonite paste can be stacked together to form a water retention layer. If the soil in the flower pot is not disturbed frequently, it is recommended to use degradable bentonite mats. The degradable bentonite mat body has environmental advantages and can provide nutrients for plant growth. If the laid bentonite mat body is not disturbed, the anti-seepage barrier layer formed by it will not be destroyed, and it can still play a good barrier and water retention role. The upper and lower layers of materials can provide nutrients for plant growth after degradation. The degradable geotextile will degrade after 1-2 years, and the degraded material can also provide nutrients for plant growth. In addition, in order not to affect In order to affect plant growth, the bentonite pad body should be set at the bottom or bottom of the flower pot to store more water without affecting the growth of plant roots. The barrier water-retaining bentonite pad is eco-friendly. Plant roots penetrate the product and the product still has excellent anti-seepage performance. In addition, the bentonite pad body has excellent resistance to dry-wet and freeze-thaw cycles, ensuring the service life of the bentonite pad body in different application environments; the bentonite pad body has excellent water-blocking and water-retaining properties, and water is not easy to penetrate. The bentonite pad body itself has water-retaining capacity and can slowly release water after drought, thereby ensuring that watering in the flower pot can last for a long time.

The degradable bentonite mat body 120 has environmental advantages and can provide nutrients for plant growth. If the laid bentonite mat body 120 is not disturbed, the anti-seepage barrier layer formed by it will not be destroyed, and it can still play a good barrier and water-retaining role. The materials of the upper and lower layers can provide nutrients for plant growth after degradation. The degradable geotextile will degrade after 1-2 years, and the degraded materials can also provide nutrients for plant growth. In addition, in order not to affect plant growth, the bentonite mat body 120 should be set at the lower part or bottom of the flower pot 110 to store more water without affecting the growth of plant roots. The barrier water-retaining bentonite pad has eco-friendly characteristics. Plant roots penetrate the product and the product still has excellent anti-seepage performance. In addition, the bentonite pad body 120 has excellent resistance to dry-wet and freeze-thaw cycles, ensuring the service life of the bentonite pad body 120 in different application environments; the bentonite pad body 120 has excellent water-blocking and water-retaining properties, and water is not easy to penetrate through it. The bentonite pad body 120 itself has water-retaining capacity and can slowly release water after drought, thereby ensuring that watering in the flower pot 110 can last for a long time.
