环境修复剂对草坪建设的影响

Study on Influence of Environmental Restoration Agent on Lawn Construction

在有氧状态下,采用水溶液聚合法合成高吸水性环境修复剂,吸水倍率为462。试验研究了此环境修复剂在施用量分别为0、50、751、00 g/m24个水平的条件下,对黑麦草生长的影响。通过2个多月的试验研究表明:施用不同量的环境修复剂与空白试验对比,可增高植物株高、增加植株密度、提高出苗率、提前出芽时间、减缓水分蒸发、改良土壤、增强抗旱性。但随着环境修复剂用量的增加,促进作用增加已不是很明显,故在施入时要考虑最佳投入量,75 g/m2是最经济合理的。可见加入适量环境修复剂对快速恢复施工破坏的植被有一定的应用价值。

In this paper, environmental restoration agent with high water absorbability is synthesized by using the water solution copolymerization in oxygen-containing atmosphere. The water absorbency ratio is 462. The effects of environmental restoration agent on ryegrass under the four level conditions of 0 g/m^2, 50 g/m^2, 75 g/m^2, 100 g/m^2 are studied through experiment. Through the experimental study in more than two months, the result shows that contrasted with the blank can promote plant height , the application of different amounts of environmental restoration agent can increase plant height and density, improve germination rate, advance sprouting time, slow down water evaporation, improve soil, and enhance drought resistance. However, the effect is not obvious with the increase of environmental restoration agent dosage. So the quantity of 75 g/m^20 is the most economical and reasonable. It is indicated that adding proper environmental restoration agent has some application value to accelerate vegetation restoration which was destructed by construction.
