胶质芽孢杆菌对黑麦草根际微生物数量的影响
Effects of Bacillus mucilaginosus agents on the quantity of microorganism in ryegrass rhizosphere
摘要
Abstract
This experiment was aimed to investigate the effect of 5 strains of Bacillus mucilaginosus, isola-ted from rhizospheres of Zea mays （K02）, Poa pratensis （K05）, Elyrnus dahuricus （K09）, Lolium perenne （K11） and Agrostis palustris （K12） resipectively, on the quantity of microorganism in ryegrass （L. perenne） rhizosphere by using a dilution coating flat method. The result showed that after fertilizing with the agents, the quantities of bacteria and actinomycetes of three different sampling periods in ryegrass rhizosphere were significantly higher than those in control. The fungi quantity of three different sampling periods in ryegrass rhizosphere tended to decrease compared with control. It indicated that the effect of B. rnucilaginosus agents on fungus quantity was negative, but they were beneficial to increase the quanti- ties of bacteria and actinomycetes in ryegrass rhizosphere.关键词
