对不同处理的番茄接种青枯病病菌研究表明 :植株发病情况与是否进行整枝有关 ,整枝所形成的伤口能感染青枯病病菌 ,但发病仍以根系病菌侵染为主 ;青枯病潜伏期的植株产量有整枝高于无整枝 ,发病期却以无整枝的产量高于有整枝 ;菌克星防治青枯病效果优于枯腐宁。生产上无出现青枯病时 ,应提倡整枝 ,而发生青枯病时则不应当整枝 ,或整枝后马上用药防治 The results showed that the incidence of the disease was related to whether the pruning was carried out. The wounds formed by the pruning could infect the bacterial wilt, but the infection was still mainly caused by the root germs. The incubation period of the bacterial wilt The yield of plants with pruning was higher than that without pruning, but the yield of pruning was higher than that with pruning during the disease period. When there is no bacterial wilt disease in production, pruning should be promoted, and when there is a bacterial wilt, the pruning should not be carried out or immediately after pruning
