衡山为湘南主要柑桔产区,全县甜橙(Citrus sinensis Osbeck.)栽培面积有8,000余亩,每年产量达5万担,对於支援国家社会主义工业建设起了一定的作用。但自1930年,由广东购运苗木时,将溃疡病(Pseudomouas citri Hasse.)带至南岳後,随即传播到该县八区,现全区受害面积已有1,700亩,其中7个乡普遍发生严重的病害。至1953年,在距离病区100华里的草市、梅洲、木陵等乡也发现病势不等的零散病树4,700株,病区已经扩大。柑桔因受病害的侵袭,果实的商品价值降低,据衡山县人民政府的统计,1953年全县甜橙病果因受差价的损失,即达10万元,而植株感病後,落叶落果的损失,尚无法估计。
Hengshan Mountain is the main citrus producing area in southern Hunan. Citrus sinensis Osbeck cultivated area has more than 8,000 mu and annual output reaches 50,000 tons. It has played a certain role in supporting the national socialist industrial construction. However, when purchasing and transporting seedlings from Guangdong in 1930, Pseudomouas citri Hasse. Was brought to Nanyue and then spread to eight districts of the county. Now 1,700 mu of land is affected in the entire district, of which seven townships are commonplace Serious disease. By 1953, there were 4,700 scattered diseased trees with varying degrees of disease found in Caoxi, Meizhou and Muling, which are 100-kilometer away from the ward. The ward has been expanded. Citrus due to the invasion of disease, the value of the fruit of the goods lower, according to Hengshan County People’s Government statistics, the county in 1953 due to the difference between the loss of sweet orange fruit, that is up to 100,000 yuan, and plant disease, deciduous Loss, can not be estimated.
