厚层客土喷播基质中不同有机质添加物对护坡植物早期生长的影响

Effects of Different Organic Matter Additives on Early Growth of Slope-Protecting Plants in Spray Seeding Substrate

针对目前大量开挖草炭土用于厚层客土喷播绿化工程,导致严重破坏草炭富集区的植被,造成大量新裸露地的现状.本研究将3种不同的农业废弃物组合:Ⅱ、生玉米秸秆+生活垃圾堆肥,Ⅲ、生玉米秸秆+尿素堆肥,Ⅳ、生玉米秸秆来替代草炭土应用于厚层客土喷播绿化工程中,与草炭土(Ⅰ)的绿化防护进行对比试验,对其理化性质及植物初期生长状况进行对比分析.结果表明,对照样方混合基质各项指标均满足植物正常生长所需的条件,植物早期生长状况良好,能达到有效代替草炭土的效果,具有较高的可行性.

In view of the present situation that the vegetation of peat-rich region are destroyed and massive new bare area are produced by excavating a large number of organic peat as soil additives used for bare slope ecological restoration, three different agricultural waste combinations straw ＆ garbage cornposting, straw ＆ carbamide, raw straw composting are selected to replace peat used in spray seeding projects. Comparison test on the effect of slope protection and analysis its of physical nature, chemical nature and the early growth conditions of plant, were conducted. The result indicated that the main index of the planting substrate can meet the growth condition of vegetation ; the early growth of the plant was in good condition; the combinations can achieve the protection effect.
