根内根孢囊霉和多菌灵对鼓粒期大豆生物量及根际土壤细菌总数的影响OA

As global soybean demand continues to rise,soybean yield has garnered increasing attention.Root rot,a typical soil-borne disease,poses a huge threat to stable and sustainable soybean production.Arbuscular Mycorrhizal Fungi(AMF)can reduce the incidence of soybean root rot,thereby enhancing yield.To explore effective methods for increasing soybean yield and promoting sustainable development,this study utilizes Kandou 3(original variety)soybean as experimental material.Field trials are conducted to investigate the effects of Rhizophagus intraradices and carbendazim on soybean biomass and total rhizosphere soil bacterial count during the pod-filling stage under rotational cropping and alternative cropping systems.The results show that compared to rotational cropping,alternate cropping reduces primary plant biomass and total bacterial count in soybeans.Under both rotational and alternate cropping systems,the Rhizophagus intraradices-inoculated treatment group exhibits greater plant height,stem diameter,root length,and above-ground fresh weight than other treatment groups.This study aims to overcome obstacles in soybean alternate cropping,enhance yield and production efficiency,and provide a novel approach for sustainable cultivation and green disease control strategies.
