利用海涂(滩)建立大型柑桔生产基地是我国发展柑桔的一个新的方向。近十余年来发展很快。在浙江省仅台州地区的温岭、黄岩、临海、三门四个县的统计,海涂新建柑桔基地面积已达三万五千亩以上,种的主要是枳砧温州蜜柑。种后几年,桔树相继发生黄化现象,影响树势、产量和果实品质。试验自1973年开始分阶段进行,对柑桔黄化的起因、条件、征状、为害性和解决途径作了一些探索(参阅《台州柑桔资料选编》,1977年)。试验证明,这种类型的黄化现象是缺索引起的营养生理病。
The use of the TURCO (beach) to establish a large-scale citrus production base in China is the development of a new direction of citrus. Nearly 10 years of rapid development. According to the statistics of Wenling, Huangyan, Linhai and Sanmen Counties in Taizhou, Zhejiang Province alone, the newly-built citrus base area in Tiantu has reached more than 35,000 mu. The main species is the orange mandarin of Hovenia dulcis Thunb. A few years later, orange trees have occurred yellow phenomenon, affecting the tree vigor, yield and fruit quality. The test has been carried out in stages since 1973, and some explorations have been made on the causes, conditions, symptoms, harmfulness and solutions of orange yellowing (See Selected citrus fruits in Taizhou, 1977). Tests show that this type of yellowing is caused by a lack of nutrition and physiology disease.
