Ｅｆｆｅｃｔ　ｏｆ　Ｂｉｏｃｈａｒ　Ａｐｐｌｉｃａｔｉｏｎ　ｏｎ

, 2013
为确定生物炭作为土壤改良剂对半干旱地区土壤持水性能的影响,以中国科学院固原生态试验站为研究基地,通过添加不同种类(锯末、槐树皮)、不同比例(1%,3%,5%,以干土质量计)生物炭的小区定位试验,研究生物炭添加6个月后表层土壤容重、田间持水量及持水性能的变化。结果表明:施入生物炭可以有效地改善土壤容重,提高土壤田间持水量和土壤的导水性能。其中槐树皮生物炭的作用效果优于锯末生物炭,且土壤的持水性能与生物炭掺量呈正相关关系。 更多还原Ａｂｓｔｒａｃｔ：Ａ　ｆｉｅｌｄ　ｅｘｐｅｒｉｍｅｎｔ　ｂａｓｅｄ　ｏｎ ...

Effects of PAA on Soil Preserving Water and Evaporation

, 2009
采用土柱法研究了不同PAA施入量对3种黄土高原主要土壤类型(黄绵土、黑垆土和塿土)的持水性能、土壤饱和导水率和土壤蒸发量的影响,以进一步阐明PAA的保水和蒸发作用。结果表明,施入PAA提高了土壤的持水性能。在未加入PAA之前黑垆土的持水性能最低,塿土的最高,黄绵土的次之;加入PAA后,黑垆土的持水能力显著增加,几乎为对照的2倍,塿土和黄绵土也都比对照高。土壤的供水能力随PAA用量的增加而增强,不同土壤类型之间表现为:塿土>黑垆土>黄绵土。未加入PAA时,3种土壤饱和导水率大小为:塿土> ...

Change of soil organic matter and water holding ability during vegetation succession in Ziwuling region

, 2003
研究表明,自然植被正向演替对土壤剖面有机质积累有显著促进作用,表现为:由弃耕地、草地、灌木、乔灌群聚到乔木的植被演替过程中,0～25cm土层有机质含量逐步增加,且演替初期的增加速度较快,而后增加速度相对变缓.植被演替过程中土壤有机质含量变化的主要原因在于植物凋落物归还量的变化.在同一时间测定的土壤剖面水分含量以及0～5cm土层田间持水量、容重、总孔度等与土壤持水性能相关的指标都与有机质含量呈极显著或显著相关,表明随剖面有机质的积累 ...

Study on Water-Holding Capacity of the Top Soil of a Steppe Reserve in the Yunwu Mountains, Guyuan, Ningxia Hui Autonomous Region

, 2006
应用离心机法测定土壤水分特征,研究黄土高原典型草原带退耕地植被恢复演替过程中土壤持水性能的变化特点及趋势。结果表明:土壤含水量与土壤水吸力之间符合幂函数θ=aSb,参数a的变化随着植被的演替呈增加趋势;由于植被的影响,在同一吸力范围内的土壤含水量不同,植被为顶级长芒草(Stipabungeana)群落时,土壤在各吸力段的含水量最高,坡耕地最低;其它群落土壤含水量随着水吸力的增加变化趋于一致;退耕地植被在演替过程中通过提高土壤有机质含量改善结构,降低容重并增加毛管孔隙度 ...
