[目的]探究长期应用稻鳖共生系统对稻田土壤养分含量、土壤细菌群落结构及其多样性的影响,为阐释稻鳖共生模式对稻田土壤微生物多样性的影响机制提供科学依据.[方法]以2年稻鳖共生田(RT2)、5年稻鳖共生田(RT5)和8年稻鳖共生田(RT8)为研究对象,采集各处理0～10 cm土层土壤样品,测定土壤养分含量,利用Illumina MiSeq高通量测序技术探究土壤细菌群落结构,对比分析不同应用年限稻鳖共生田的土壤养分含量及土壤细菌群落多样性差异.[结果]长期应用稻鳖共生系统明显提高稻田土壤的全氮、全磷、碱解氮和速效磷含量及土壤pH,5年稻鳖共生田的全磷和速效磷含量显著高于2年稻鳖共生田(PRT8处理>RT2处理.各样...

【Objective】To explore the effects of rice-turtle co-cultureon soil fertility,soil bacterial community structure and diversity,and to provide a scientific basis for explaining the mechanism of rice-turtle co-culture on soil microbial diversity in paddy fields.【Method】Soil samples from paddy fields of 2-year rice-turtle co-culture field(RT2)and 5-year rice-turtle co-culture field(RT5)and 8-year rice-turtle co-culture field(RT8)were collected from 0-10 cm soil layer of each treatment to determine the soil nutrient content. Illumina MiSeq high-...
