一、果园的规模与生产效率 美国柑桔栽培集中于四个州。我们访问的加利福尼亚州和佛罗里达州,柑桔栽培面积和产量占全国的百分之九十左右,其集中情况可见一斑。以佛罗里达州与我国相比,该州柑桔面积不及我国(台湾省未计在内)的十分之九,而年产量超过我国的十倍。在佛罗里达州中部的一个称为克莱蒙镇,耸立着一个供游览用的柑桔塔,二十二层,近七十米高。登高眺望,四方皆桔,借助望远镜也望不到柑桔园的边缘,据统计周围二千平方英里,柑桔树达一千七百万株。如此集中、成片的果园规模实属罕见。 First, the size and efficiency of orchards Citrus cultivation in the United States concentrated in four states. The areas and yields of citrus cultivation in the states of California and Florida we visit are about ninety per cent of the country, as evidenced by their concentration. In Florida, compared with my country, the area of ​​citrus in the state is less than nine-tenths of that of our country (not counting Taiwan Province), while the annual output of citrus is more than ten times that of our country. In Clermont, a town in central Florida, stands a citrus tower for sightseeing, twenty-two stories, nearly seventy meters high. Looked up, all four are orange, with the help of telescopes also can not see the edge of citrus orchards, according to statistics around 2,000 square miles, citrus trees up to 17 million. So concentrated, into a piece of orchard size is rare.
