Effect of Membranes and Inhibitors on Soil Evaporation

, 2003
通过培养试验研究了聚氨酯膜、渗水布膜覆盖物和聚丙烯酸钠 (保水剂 )、聚乙烯醇、聚丙烯酰胺、海藻糖蒸发抑制剂对土壤蒸发的影响。结果表明 :聚氨酯膜、渗水布膜对黑垆土蒸发有极显著影响 ,聚氨酯膜与渗水布膜的抑制作用差异极显著 ;聚氨酯膜对沙土蒸发有显著的抑制作用 ;几种抑制剂对土壤蒸发的抑制作用以保水剂最好 ,其效果随用量的增加而增大 ;沙土中加入海泡石或草炭 ...

Mathematical simulation of soil evaporation from wheat/maize

, 2013
 为了探明小麦/玉米套作条件下棵间土壤蒸发规律及内在机制,该文将Ritchie模型和间套作群体光能传输模型结合起来模拟了小麦/玉米套作田的棵间土壤蒸发,并用2012年和2013年微型蒸渗仪的实测值对该方法进行了验证。结果表明,2 a模拟值和实测值的变化趋势都非常一致。与实测蒸发相比,该文所建模型2012年模拟结果的均方根误差为0.447 mm/d,平均绝对误差为0.331 mm/d,分别比原Ritchie模型降低16.8%和20.8%。在实测数据的88 d,累计实测蒸发量为107.2 mm,

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> ...
