摘要:

随着设施种植业的迅速发展,畜禽粪污有机肥在设施种植中得到广泛应用,畜禽粪污是设施种植土壤中抗生素的主要来源之一。土壤中的抗生素可被农作物吸收,并通过食物链传递,最终威胁人类健康。以设施蔬菜种植大县河北省永清县施用猪粪有机肥的日光温室为研究对象,研究畜禽粪污有机肥抗生素残留对日光温室土壤抗生素生态风险和生物多样性的影响。通过测定猪粪、日光温室土壤中抗生素的种类及含量,采用风险商值法评价各种抗生素的生态风险;采用宏基因组方法测定微生物群落特征,探究抗生素残留对土壤微生物多样性的影响。结果表明:(1)猪粪和日光温室土壤样品中共检出7种典型兽用抗生素分别为磺胺二甲基嘧啶(SM2)、诺氟沙星(NOR)、环丙沙星(CIP)、恩诺沙星(ENR)、四环素(TC)、土霉素(OTC)、金霉素(CTC)。(2)猪粪中恩诺沙星和金霉素的浓度最大,风险商值(RQ)分别为28.26和1.23,均大于1.0,都存在生态高风险。施用猪粪日光温室土壤中恩诺沙星、土霉素和金霉素的浓度最大,RQ值均在0.1~1.0之间,均存在中等生态风险。(3)施用猪粪有机肥对于日光温室土壤中微生物群落结构具有一定影响,改变了微生物优势菌群的丰度排名,施用猪粪的土壤中相对丰度排名第四的优势菌门由奇古菌门变为绿弯菌门。研究显示,施用猪粪引起可产生抗生素的类诺卡氏菌属(Nocardioides)相对丰度增加,达到空白对照的2倍以上。

Abstract:

In recent years, the facility planting industry has developed rapidly. Organic fertilizers derived from livestock and poultry manure have become widely used in facility planting. Animal manure is one of the primary sources of antibiotics in the soil of facility planting. These antibiotics can be absorbed by crops and transmitted through the food chain, ultimately posing a threat to human health. The study focused on the impact of antibiotic residues in pig manure organic fertilizer on the ecological risk and biodiversity of soil antibiotics in a solar greenhouse in Yongqing County, Hebei Province, a major vegetable planting county. By measuring the types and contents of antibiotics in pig manure and greenhouse soil, the ecological risk of various antibiotics was evaluated using the risk quotient method; the characteristics of the microbial community were determined using metagenomic methods, and the impact of antibiotic residues on soil microbial diversity was explored. The results showed that: (1) seven typical veterinary antibiotics were detected in pig manure and greenhouse soil samples, namely sulfamethoxazole (SM2), norfloxacin(NOR), Ciprofloxacin(CIP), Enrofloxacin(ENR), Tetracycline(TC), Oxytetracycline(OTC) and Chloramphenicol(CTC). (2) The concentrations of enrofloxacin and aureomycin in pig manure were the highest, with RQ values of 28.26 and 1.23, both greater than 1.0, indicating a high ecological risk. The highest concentrations of enrofloxacin, oxytetracycline and chlortetracycline were observed in the soil of the greenhouse where pig manure was used, with RQ values ranged from 0.1 to 1.0, indicating moderate ecological risks. (3) The application of pig manure organic fertilizer had a certain impact on the microbial community structure in greenhouse soil, changing the abundance ranking of dominant microbial communities. Specially, the fourth dominant bacterial phylum in the soil treated with pig manure had changed from Archaea to Chloroflexi. Research had shown that applying pig manure led to an increase in the relative abundance of Nocardioides, bacteria capable of producing antibiotics, which reached more than twice that of the control group.
