以捕捉孢子的方法观察设施番茄灰霉病菌分生孢子扩散的时间和空间动态,结果表明番茄灰霉病菌分生孢子在温棚内扩散是随机的,不同高度孢子捕捉量没有明显差异。番茄灰霉菌分生孢子扩散主要集中在白天,从8:00到20:00,孢子捕捉量占全天总量的88.4%,而8:00以前和20:00以后孢子捕捉量较小,仅占全天总量的11.6%,每日10:00后捕孢量开始迅速增加,而16:00后明显下降以10:00~16:00的捕孢量最多最稳定,1 d中最大捕孢量出现在12:00~14:00时。分生孢子捕捉量与对应田间病情指数呈显著正相关(R =0.8850,P <0.01),因此通过捕捉分生孢子,并监测其扩散动态,预测番茄灰霉病的发生期及防治适期具备可行性。
以捕捉孢子的方法觀察設施番茄灰黴病菌分生孢子擴散的時間和空間動態,結果錶明番茄灰黴病菌分生孢子在溫棚內擴散是隨機的,不同高度孢子捕捉量沒有明顯差異。番茄灰黴菌分生孢子擴散主要集中在白天,從8:00到20:00,孢子捕捉量佔全天總量的88.4%,而8:00以前和20:00以後孢子捕捉量較小,僅佔全天總量的11.6%,每日10:00後捕孢量開始迅速增加,而16:00後明顯下降以10:00~16:00的捕孢量最多最穩定,1 d中最大捕孢量齣現在12:00~14:00時。分生孢子捕捉量與對應田間病情指數呈顯著正相關(R =0.8850,P <0.01),因此通過捕捉分生孢子,併鑑測其擴散動態,預測番茄灰黴病的髮生期及防治適期具備可行性。

To evaluated the dynamics of sporangium diffusion in Tomato Botrytis cinerea and its correlation with disease incidence in greenhouse,observation the dynamic time and space of airborne spores of Tomato Gray Mold by trapped the conidium was assayed.The results showed that the diffusion of Botrytis cinerea on the time and space are randomly Sporangium diffusion occurred mainly during daytime and 88.4% of Botrytis cinerea were trapped during 8:00 to 20:00.The trapped quantity of Botrytis cinerea increased after10:00 and reducedafter 16:00 quickly,and the maximum quantity of conidium Trapped occurred between 12:00 to 14:00. Our results suggest that the trapped quantity of Botrytis cinerea correlated with the Disease index of Gray Mold in the greenhouse during mid to late March to late Aprill (R=0.8850,P <0.01)significantly,and it will be benefit for the predict tomato gray mold and select suitable date for control.
