Degradable ecological bag
The invention provides a degradable ecological bag. The degradable ecological bag comprises an upper light-exposed part and a lower light-invisible part, wherein the lower light-invisible part is made of biodegradable geotechnical cloth to realize degradation and facilitate biological activities. The ecological bag is a flat rectangular cuboid formed by sewing three edges of two pieces of geotechnical cloth on the top surface of the upper light-exposed part and the bottom surface of the lower light-invisible part, and the other edge is opened to be filled with a mixture of a matrix and grass seeds. The bottom surface is made of biodegradable geotechnical cloth which can be degraded under the action of water and soil microorganisms. The degradable ecological bag has the anti-scouring and soil-fixing effects of a traditional geotechnical cloth ecological bag in the early growth stage of vegetation, and provides a base condition for plant growth; after the growth of plant roots is completed and plants play the anti-scouring and soil-fixing effects, the external traditional geotechnical cloth is exposed to sunlight and can be degraded, the biodegradable geotechnical cloth at the internal light-invisible part can also be degraded under the action of water and microorganisms in soil, and the degradation rate can reach 70-90% within 120 days. The influence on the environment is reduced, and the ecological effect of slope protection of the ecological grass planting bag is improved.
一种可降解生态袋，包括上部见光部分和下部不见光部分，所述下部不见光部分采用生物降解土工布以实现降解及利于生物活动。所述生态袋由上部见光部分的顶面和下部不见光部分的底面两片土工布沿三边缝合成外形呈扁平状矩形长方体，另一边开口以装填基质与草籽混合料。所述底面采用在水和土壤微生物作用下可降解的生物降解土工布。本发明在植被生长初期具有传统土工布生态袋防冲固土作用，为植物生长提供基底条件；待植物根系生长完成、植物自身发挥防冲固土作用后，外部传统土工布暴露于阳光中可降解、内部不见光处的生物降解土工布受土壤中的水和微生物作用也可降解，120天降解率可达到70～90％。减少了对环境的影响，提升了生态植草袋护坡的生态效果。
