Biocontrol Efficacy on Fusarium Wilt of Banana by the Collaborative of Acid Soil Ameliorant and Biocontrol Materials
摘要
Abstract
Fusarium wilt of banana is a lethality soil-borne disease and it is very important to control the threaten.Biocontrol efficacy on Fusarium wilt of banana was evaluated in this study based on greenhouse condition and physiological and biochemical analyzation,and the biocontrol materials were acid soil ameliorant collaborated with bioorganic fertilizer and actinomycetes agents.The results were listed as follows:treatments of collaborative of acid soil ameliorant and biocontrol materials (ActA and BIOA) showed higher biocontrol efficacy (61.1% and 58.3%) than those of Act (55.6%) and BIO (52.8%),respectively.The soil pH value of ASA,Act,BIO,ActA and BIOA increased to some degree,and significantly higher than that of CK (5.13) (p<0.05) at the end of experiment (56 days after transplanting).Application of biocontrol materials could significantly reduce the population of F.oxysporum in banana rhizosphere soil (p<0.05) and the collaborative of acid soil ameliorant strengthened this effect.Treatments ActA and BIOA could also significantly increase bacteria population,while decrease fungi population.Compared with CK,the stem diameter,length and biomass of banana plant in all treatments increased significantly and the organic matter,organic carbon,total nitrogen,available potassium and electric conductivity also increased.关键词
