| 摘 要： | 水分是华北土石山区植被恢复的主要限制性因子,采取有效措施减少土壤水分蒸发,维持植物根系附近的土壤含水量,提高土壤保墒能力,是该地区植被恢复的关键.采用保水剂和多功能可降解地膜2种保墒材料对土壤含水量进行研究,结果表明,2层土壤含水量均在液体地膜45 m l/穴处理达到最高值,而保水剂对土壤含水量的影响小于液体地膜. |
| 关 键 词： | 土壤含水量 保墒材料 保水剂 液体地膜 华北土石山区 |

| Abstract: | Water is a major restrictive factor for vegetation rehabilitation in mountainous area of North China.How to reduce water vaporescence with effective measures to maintain water content around root system and to improve soil's water retention is the key for vegetation rehabilitation in this particular area.Two materials namely chemical preparation for water content and resolvable ground membrane cover were adopted to study soil's water content.As a result,water content of two soil layers was the highest at 45... |
| Keywords: | soil's water content material for water retention chemical preparation liquid ground cover mountainous area of North China |
