伦敦新闻社消息:科学家们正着手使衰落了30年的英国甜樱桃种植业起死回生。肯特郡及英国其他地区的传统樱桃园已日益无利可图,主要原因是这些园生长的樱桃树体太大,间距12米以上,在采摘及管理上都很不经济。此外,产量年年波动不定,而且事实证明:防止大量果实落入鸟嘴是办不到的,樱桃雨后落果也带来更大的损失,同时,细菌性癌肿病对樱桃树本身也是一个日益严重的
LONDON: Scientists are working to revive a 30-year-old British sweet cherry plantation. Traditional cherry orchards in Kent and elsewhere in the UK have become increasingly unprofitable, mainly because the cherry trees that grow in these gardens are too large, spaced more than 12 meters apart, to be uneconomical in both picking and management. In addition, the output fluctuates year after year, and it turns out: to prevent a large number of fruit from falling into the beak can not be done, cherry fruit loss also brings greater losses, while bacterial cancer is also a cherry tree itself Increasingly serious
