四川柑桔产量冠于全国,1986年达65万吨。据1985年不完全统计柑桔栽植株数达2亿株,约150余万亩,结果树约占总株30％,投产树亩产不过1000斤,其中78％属于中低产树,若将这批中低产树复壮,提高着果率,则四川柑桔可很快成倍翻番。真武实验场五月红甜橙弱树低产,近十年产量变幅呈 Sichuan citrus production crown in the country, up to 650,000 tons in 1986. According to incomplete statistics in 1985, the number of citrus plants reached 200 million and about 150 million mu. The result tree accounted for about 30% of the total plant. The output of mu trees was only 1,000 mu, of which 78% belonged to middle-low yield trees. Middle-low yield trees rejuvenation, improve the fruit rate, the Sichuan citrus can be doubled quickly. Maywu experimental field May red sweet orange trees low yield, yield showed nearly ten years
