| 摘 要： | 本文研究了温湿度对枯草芽胞杆菌B36菌株可湿性粉剂防治番茄灰霉病效果的影响。结果表明：枯草芽胞杆菌B36菌株可湿性粉剂在相对湿度90%时，对番茄灰霉病保护和治疗效果最高，分别达82.9%和61.63%；在相对湿度100%时，对番茄灰霉病保护和治疗效果最差，分别达32.87%和31.63%。当相对湿度为90%，温度在30 ℃∥20 ℃条件下，对番茄灰霉病的保护和治疗效果分别为82.48%和63.01%；温度在25 ℃∥15 ℃条件下，对番茄灰霉病的保护和治疗效果分别为45.06%和23.85%。表明湿度及温度对枯草芽胞杆菌B36菌株可湿性粉剂防治番茄灰霉病的效果具有较大影响。

| Abstract: | The effects of humidity and temperature on Bacillus subtilis B36 WP were studied in the laboratory. The results showed that, at a relative humidity (RH) of 90%, the protection and control efficiency of the preparation of B. subtilis B36 WP was 82.9% and 61.63%, respectively; at RH 100%, 32.84% and 31.63%; at RH 90% and 30 ℃ or 20 ℃, 82.48% and 63.01%. It was shown that humidity and temperature had a greater impact on the efficacy of B. subtilis B36 WP to Botrytis cinerea. |
