1989年,我国水果总产量达1990万吨,其中苹果为530万吨(超过了同年美国苹果的总产量440万吨),柑桔438万吨,梨约300万吨。人均水果占有量为15kg。从总产量看,我国水果生产和其它国家相比差距不大,但从单产、果品质量和人均占有量来衡量,则我国与一些先进国家之间还有相当大的一段差距。为了缩短差距,

In 1989, China’s total fruit output reached 19.9 million tons, of which 5.3 million tons were apples (more than the 4.4 million tons of U.S. apples in the same year), 4.38 million tons of citrus and about 3 million tons of pear. Per capita fruit possession of 15kg. Judging from the total output, there is not much difference between our country’s fruit production and other countries. However, there is still a considerable gap between China and some advanced countries in terms of yield, fruit quality and per capita possession. In order to shorten the gap,
