摘要
茂谷柑裂皮病使枳砧或枳橙砧的茂谷柑树势衰退,产量和品质下降,严重时落叶,花小、畸形,落花落果,植株死亡,是目前茂谷柑的主要病害之一。种植无病苗、规范操作,可以避免裂皮病的发生,对于已出现典型性症状的果园,如果发病率在3%左右,原则上把病株清除掉,如果超过10%,但仍有产量,暂时可以通过靠接技术延缓病情的发展,减少经济损失。
Exocortis viroid is one of the disease causes poncirus trifoliate stock ＂Murcott Tangor＂ tree vigor to get weakened, production and fruit quality to sharp cut off. Seriously this disease might make the tree leaves fall, the flower grow smaller and malformed, the fruit and flower drop, at the end the tree wiU go die. By establishing disease-free nursery, standardizing operation can reduce the risk of infection. For the infected poncirus trifoliate stock of ＂Murcott Tangor＂ the disease tree, and if orchard, in order to reduce economic losses, if the incidence is about 3% that can cut off the incidence is over 10% that can use approach production recover temporarily. grafting to make the tree vigor and
