日光温室白菜棵间土壤蒸发变化规律试验研究

open access: yesShuitu Baochi Xuebao, 2008
土壤蒸发在农田水量平衡和能量平衡计算中占有重要地位。本文采用微型蒸渗仪测定温室白菜的棵间土壤蒸发,对白菜棵间土壤蒸发的变化规律及其与太阳辐射、气温和相对湿度等主要气象因子的关系进行了试验研究和分析。研究结果表明:温室白菜棵间土壤蒸发随着白菜生育期的推移有减小的趋势,棵间土壤蒸发量占全生育期总耗水量的39.57%~42.03%,棵间土壤蒸发与太阳辐射、气温和相对湿度等主要气象因子均呈现良好的指数关系,本研究对合理制定温室白菜的灌溉制度具有重要的参考价值。

喀斯特森林近地表层覆盖对碳酸盐岩红土蒸发过程的影响

open access: yesShuitu Baochi Xuebao, 2020
蒸发是西南喀斯特地区薄层土壤水分损失的主要途径,浅层土壤水分的存蓄对喀斯特地区农业生产和生态恢复至关重要。以西南喀斯特森林碳酸盐岩红土为研究对象,基于室内蒸渗试验设置4个苔藓生物量(0,0.32,0.64,0.95 kg/m2)和3个松针生物量(0,0.32,0.64 kg/m2)共12种处理,分析森林近地表层覆盖对碳酸盐岩红土蒸发过程及表层温度时空分布的影响规律,并对比3种蒸发模型(Black、Rose、空气动力学蒸发模型)在喀斯特森林碳酸盐岩红土的适用性。结果表明 ...
