| 摘 要： | 在17种载体中玉米粉玉米芯粉载体最适宜于 GVP 的生长和产孢。在灭菌土盆栽试验和田间小区试验中,用这种载体制成的菌粉单独或与低量 PCNB(每千克±10mg)联合防治出苗前和出苗后的杉苗立枯病(Rhizoctonia solani)都是有效的,但后者优于前者。GVP 菌粉加到灭菌土壤中2周,它的群体数量增到10~8数量级,以后逐渐下降在10~5～10~6数量级之间波动;而 R.solani 的群体数量却急剧下降并保持在一个很低的水平。

| Abstract: | Among 17 carriers,corn-powder with cob-powder carrier was found the most suitable for growth and sporulation of Gliocladium virens(GVP).In both pot experiment(sterile soil)and field plot trial(natural soil),either the GVP preparation alone or its combination with a low dose(10mg/kg soil) of PCNB was effective in controlling post-and pre-emergence damping-off of Cunninghamia lanceolata seedlings causcd by Rhizoctonia solani,and the latter was superior to the former.Two weeks after the addition of the GVP preparation to sterile soil,population of the GYP increased up to 10~8 and that of R.solani suddenly declined and then the two gradvally doercased respectively. At last,population of the GVP fluctuated from 10~5 to 10~6 and that of R. solani was kept in a very low level. |
