植物纤维毯覆盖对狗牙根等种子发芽的影响
摘 要
生态护坡是依靠植物的根系的拉力以及摩擦力对土壤进行固定,增强土壤的稳定性。不同植物的根系生长特征不同,所以,对边坡防护植物的选择是生态边坡防护工程的重要环节,植物选择的正确与否将直接决定着防护效果的好坏。植物纤维毯主要在植物播种后对边坡进行防护,减缓径流,控制地表侵蚀,改善植物生存的外界条件,从而达到坡面绿化防护的效果。植物纤维毯的防护方案的对比,通过对现场试验区的植物萌发、生长情况调查,综合考虑植物纤维毯成本和护坡效果,以确定一种最合适的植物纤维毯生产规格,应用至实际护坡过程中。

Effects of plant fiber blanket on germination of seeds such as canine root
ABSTRACT
Ecological slope protection relies on the tension and friction of the root system of plants to fix the soil and enhance the stability of the soil. The root growth characteristics of different plants are different, so the selection of slope protection plants is an important part of the ecological slope protection engineering, and whether the plant selection is correct or not will directly determine the protection effect. The plant fiber blanket mainly protects the slope after planting, slows down the runoff, controls the surface erosion, and improves the external conditions of plant survival, so as to achieve the effect of slope greening protection. The comparison of the protection scheme of plant fiber blanket, through the investigation on the germination and growth of plants in the field test area, the cost of plant fiber blanket and the effect of slope protection are comprehensively considered to determine the most suitable production specifications of plant fiber blanket and apply it to the actual slope protection process.
