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。
The corncob corncob vector was the most suitable for GVP growth and sporulation in 17 vectors. In sterilized pot experiments and field plots, bacterial powder made from this carrier was used alone or in combination with low amounts of PCNB (± 10 mg / kg) to control pre- and post-emergence Rhizoctonia solani Are valid, but the latter is better than the former. GVP powder added to sterilized soil for 2 weeks, its population increased to 10 to 8 orders of magnitude, then gradually decreased between 10 ~ 5 ~ 10 ~ 6 fluctuations in the order of magnitude; and R. solani population declined sharply and Maintain at a very low level.
