中文摘要	甘肃黄土高原干旱半干旱区裸露边坡年均降水量少、气候干燥、蒸发强烈,导致边坡绿化植物存在出苗难和成活率低等诸多问题。本研究以干旱半干旱区裸露边坡为研究对象,通过L9(34)正交试验,研究生物肥、保水剂、草炭土、土壤、秸秆、速效肥6种喷播绿化基质在不同用量和比例组合下的理化性质,及其对边坡水分蒸发量、植被盖度、地上植物量的影响,以期筛选出适宜的喷播绿化基质配方。结果表明,草炭土∶ 土壤∶ 秸秆比例为40∶ 45∶ 15,嗜盐碱微生物菌肥500 g·m~(-2)、保水剂1 g·m~(- 2)、速效肥25 g·m~(-2)可有效减小水分蒸发量,提高植被盖度和地上植物量,对黄土高原裸露边坡植物生长最为有利。
英文摘要	Arid and semi-arid region of uncovering slope in Loess Plateau had less annual precipitation with dry climate and intense evaporation in Gansu Province which leads to many problems of uncovering slope greening plants including germination difficult and lower survival rates. The present study compared the physicochemical properties of 6 different spraying and sowing substrate including biological fertilizer,super absorbent polymer,peatmoss,soil,straw and fast released fertilizer with different dosage and proportion and their effects on slope water evaporation,vegetation coverage and biomass in uncovering slope of loess plateau to screening green substrate suitable for these areas. The results showed that the substrate with peatmoss,soil and straw in a ratio of 40∶ 45∶ 15 and addition with 500 g·m~(-2) saline microbial fertilizer, 1 g·m~(-2) absorbent polymer and 25 g·m~(-2) fast released fertilizer can effectively reduce water evaporation,increase the vegetation coverage and aboveground biomass which was the most benifical for the growth of plants of Loess Plateau uncovering slope.
