边坡厚层基材喷播复绿新基材研究

Study on the New Base Materials for Spray Seeding and Greening of the Thick Base Materials of Slope

目前边坡喷播复绿工程基材的主要基质多采用东北泥炭土,而过度开采泥炭土必然导致东北的生态环境遭到破坏。基于此,研制了一种可替代东北泥炭土的高陡边坡复绿厚层新基材(绿色有机)。从试验基地选取、场地划分、农家肥选定发酵,到基材配比、搅拌喷射、每天养护、定期数据收集整理,最后从发芽率、覆盖率、基质理化性能、经济、意义进行比较分析,结果表明,这种新的基质能够替代东北泥炭土的使用,并在后续同类项目进行了应用,效果显著,为同类行业提供了重要参考。

At present, the Northeast peat soil is mostly used as the main base material of the slope spray seeding and greening project base materials, and excessive exploitation of peat soil will inevitably lead to the destruction of the ecological environment in Northeast China. Based on this, greening thick new base materials for high steep slope(green organic) was developed to replace the peat soil in Northeast China. From the selection of the experimental base, the division of the site, the selection and fermentation of farmyard manure, to the proportion of base materials, stirring and spraying, daily maintenance, regular data collection and sorting, and finally comparative analysis from germination rate, coverage rate, physical and chemical properties of the base material, economy and significance. The results show that this new base material can replace the use of peat oil in Northeast China, and it has been applied in the following similar projects, and the effect is remarkable, which provides important reference for similar industries.
