微咸水与再生水混灌对土壤特性的影响与灌溉效应评估

Shuitu Baochi Xuebao, 2022
为了探讨淡水资源不足地区微咸水的合理利用方式。通过盆栽试验, 以清水灌溉为对照, 研究不同比例微咸水与再生水混合灌溉对水盐、水溶性离子、滴水穿透时间WDPT、有机质以及酶活性的影响, 并利用第二代生物综合响应指数法(IBRv2)对微咸水与再生水混灌效应进行评价。结果表明: (1)与再生水灌溉(T1)相比, 随着混合溶液中微咸水比重的升高, 土壤含水率和含盐量逐渐升高且差异显著(P＜0.05)。(2)与T1处理相比, 随着混合溶液中微咸水比重的升高, 土壤K+、Ca2+含量呈降低趋势, Na+、Cl ...

Synchrotron-radiation computed tomography of the water drop penetration time test on hydrophobic soils

Journal of Rock Mechanics and Geotechnical Engineering
The water drop penetration time (WDPT) test consists of placing water drops on a material's surface in order to evaluate how long it takes to penetrate the pores. It is used to evaluate the hydrophobicity of materials. This study aims at investigating in

Impacts of thinning of a Mediterranean oak forest on soil properties influencing water infiltration

Journal of Hydrology and Hydromechanics, 2017
In Mediterranean ecosystems, special attention needs to be paid to forest–water relationships due to water scarcity. In this context, Adaptive Forest Management (AFM) has the objective to establish how forest resources have to be managed with regards to ...

Influência da concentração de extratos hidrofóbicos na repelência à água em solos arenosos

Pesquisa Florestal Brasileira, 2011
A repelência à água é estudada em vários solos do  mundo, sendo os casos mais extremos encontrados  em solos arenosos. Acredita-se que a repelência à  água seja causada pelo recobrimento das partículas do  solo por compostos hidrofóbicos derivados da ...
