摘要:
以莠去津降解菌和硅藻土为试材制备修复菌剂,通过对菌体存活率的测定,研究菌剂对贮藏时间、温度和紫外线的耐受能力。同时采用盆栽试验方法,测定菌剂对莠去津的去除效果,并比较菌剂施用前后黄瓜根部丙二醛(MDA)、过氧化物酶(POD)、多酚氧化酶(PPO)、超氧化物歧化酶(SOD)等氧化应激指标的变化。结果表明,菌剂在室温条件下存放28 d后,菌体存活率仍高达83%,对高温和紫外线照射也表现出较强的抗性。盆栽试验中,菌剂施用28 d后,莠去津的去除率最高,接近80%。氧化应激指标变化表明,菌剂能够减少黄瓜根部MDA积累,提高POD、PPO和SOD活性。不难看出,以硅藻土为载体的修复菌剂性状良好,不仅能够高效去除土壤中的莠去津残留,还能减轻莠去津对敏感作物的伤害作用。
