Shuitu Baochi Xuebao, 2007 选取陕北延安地区原油和黄绵土，设计了完全混合和表面施油两种处理方式，通过盆栽试验，研究了不同浓度石油污染处理对植物生长和土壤呼吸的影响。结果表明，玉米和紫花苜蓿在完全混合的油污土壤上萌发良好，但生长受阻，而表面喷洒处理的石油污染严重影响紫花苜蓿的萌发和生长；土壤呼吸作用对石油污染十分敏感，完全混合处理土壤呼吸与石油污染比例成正相关关系，污染越重，土壤呼吸强度越大，所有污染处理1周后土壤呼吸强度出现抑制而迅速回落，并在波动中逐渐趋于稳定，但仍然显著高于对照组，表明黄土中存在对石油耐受的土著微生物群落。

Shuitu Baochi Xuebao, 2003 对紫花苜蓿品种西香和会宁不同刈次和不同深度土壤含水量测定结果表明,在不同刈次,引进种土壤含水量明显小于当地种;不同深度土壤含水量引进种西香明显小于当地品种会宁,且多数表现为高—低—高"V"字型变化。但在60～80cm,80～100cm土层,土壤含水量变化有所波动。这种规律性变化与引进种根系强大、有较强的生长势与生长量以及外界降水有关。引进种能吸收深层土壤的水分,且有较强的增产潜力和抗旱能力。
