对单体大棚、联体大棚番茄的生育期及灰霉病发生情况进行系统调查,对联体大棚同期种植番茄叶、花、果上灰霉病病情进行系统调查,并同步进行大棚温、湿度自动记载。结果表明,大棚番茄定植早的灰霉病发生早、发生重,病害发生盛期为花、果期。花、果期温度低于20℃、湿度高于85%时有利病害发生;结果还表明,番茄灰霉病病叶与病花、果的发生无密切相关,而病花与病果的发生具显著正相关性。
Systematic investigation was carried out on the growth period and the occurrence of gray mold in the greenhouse and the greenhouse of the greenhouse. The disease status of tomato leaves, flowers and fruit on the same greenhouse was systematically investigated. The temperature and humidity of the greenhouse Record. The results showed that the gray mold occurred earlier and heavier in tomato shedding in greenhouse. The peak period of disease was flower and fruit. Flowers and fruit temperature below 20 ℃, humidity is higher than 85% favorable disease occurs; the results also show that tomato gray mold disease and diseased flowers, fruit occurrence is not closely related to the occurrence of diseased flowers and disease with Significant positive correlation.
