增施不同微生物菌剂对棉田土壤养分及微生物群落结构影响
Effect of different microbial agents on soil nutrients and microbial community structure of cotton fields
摘要
Abstract
As a novel type of fertilizer,microbial inoculants can improve soil quality and enhance fertilizer efficiency.To investigate the effects of three microbial inoculants on soil nutrient levels and microbial communities in cotton fields,this study conducted a field plot experiment with four treatments:no inoculant(CK),1.2 kg·hm-2 of Fungi Under Heaven microbial agent(HF),75 kg·hm-2 of Bingtuan Aerospace Zhaofeng microbial agent(HS),and 150 kg·hm-2 of Zhuangke microbial agent(ZK).The changes in soil nutrients and differences in microbial community structure were analyzed.The results showed that applying microbial inoculants enhanced soil fertility,increased soil organic matter(OM),available nitrogen(AN),available phosphorus(AP),and available potassium(AK).The aqueous solution of the same strain was more effective than the powder form.Among the three microbial agents,Zhuangke microbial agent had the best effect on improving soil nutrients,followed by Bingtuan Hangtian Zhaofeng microbial inoculant.The application of microbial inoculants decreased the richness and diversity index of soil bacterial community,but had little effect on the richness and diversity of soil fungal community.Microbial inoculants increased the relative abundance of Bacillaceae but decreased the relative abundance of Chaetomiaceae in the soil.The soil nutrient factors affecting bacterial and fungal community composition were different:for bacteria,the order was total phosphorus(TP)＞AN＞OM＞total nitrogen(TN)＞AK,while for fungi,it was AN＞AP＞TN＞OM＞TP.Soil TN,AN,and OM were common factors affecting the distribution and diversity of soil fungal and bacterial communities.In conclusion,the application of Bacillus-containing microbial inoculants was beneficial to increasing soil organic matter and available nutrient contents,as well as enhancing the relative abundance of Bacillaceae in the soil.These results could provide data supports for the popularization and application of microbial inoculants in cotton fields in northern Xinjiang.关键词
