Abstract
本发明公开一种有利于降低石油烃污染的土壤培养基，该土壤培养基的组分及其重量份为：粘土30-40份，蒙脱石10-15份，有机质50-70份，海藻糖脂2-4份，缓释肥3-5份，团粒剂0.5-0.8份，冷蒿种子2-3份，百脉根种子2-3份。本发明的土壤培养基可以降低石油烃污染对植物生长的影响。
Description
技术领域
本发明涉及一种用于土壤改良的土壤培养基，尤其是一种专门用于石油烃污染的植物生长土壤培养基。
技术背景
石油是由上千种化学性质不同的物质组成的复杂混合物，石油的开采、冶炼、使用和运输过程的污染和遗漏事故，以及含油废水的排放、污水灌溉，各种石油制品的挥发、不完全燃烧物飘落等引起一系列土壤石油污染问题。特别是石油开采过程产生的落地原油，已成为土壤矿物油污染的重要来源。许多研究表明，石油烃类进入动物体内后，对哺乳类动物及人类有致癌、致畸、致突变的作用。土壤的严重污染会导致石油烃的某些成分在粮食中积累，影响粮食的品质，并通过食物链，危害人类健康。
发明内容
本发明的目的在于针对石油烃污染的土壤，提供一种原料来源广泛、成本低廉、可变废为宝的人工土壤培养基。
为实现以上目的，本发明的一种有利于降低石油烃污染的土壤培养基，其组分及其重量份为：粘土30-40份，蒙脱石10-15份，有机质50-70份，海藻糖脂2-4份，缓释肥3-5份，团粒剂0.5-0.8份，冷蒿种子2-3份，百脉根种子2-3份。
所述有机质为动物性脂肪及动物粪便。
所述缓释肥为专用复合肥和过磷酸钙，所述专用复合肥和过磷酸钙体积比为1：1，所述专用复合肥为含有氮、磷、钾养分的肥料，其中氮、磷、钾的重量比为1.5:1:1。
本发明产生的有益效果为，本发明的土壤培养基可以降低石油烃污染对植物生长的影响，具有更强的耐有机污染、耐盐碱、耐瘠薄能力和养分获取能力；培养基呈弱酸性状态，适于栖息各种微生物，能抑制病原菌的繁殖，其中冷蒿及百脉根是具有超量吸收和累积石油烃的能力的植物，使用海藻糖脂能够进一步增强冷蒿对土壤的修复。
