我省柑桔的栽植密度,和国内外各地一样,近卅年来也是不断从稀向密发展。自五十年代到六十年代初,闽侯地区多为实生树,每亩种植3株左右;闽南一带多为高压和嫁接树,每亩种植40～50株。从六十年代后期到七十年代以后,全省各地栽植密度普遍提高,大部分每亩达60株以上。从现有栽植密度的柑桔生长情况来看,亩种50～70株左右的柑园,一般种后第四年开始正式投产,在种后8～9年进入高产期的同时,树冠就已密蔽封行,此后产量即随树势的衰退而不断下降,丰产期短,早期和后期都不能获得高产,所以这样的栽植密度是不够理想的。
The planting density of citrus in our province is the same as that of other places both at home and abroad. From the 1950s to the early 1960s, mostly in Minhou area, there were mostly live trees, with about 3 plants per mu. In the area of Minnan, there were mostly high-pressure and grafted trees with 40-50 plants per mu. From the late 1960s to the seventies, planting density throughout the province generally increased, most of more than 60 per acre. From the existing planting density of citrus growth point of view, acres of about 50 to 70 orchards, generally the fourth year after the official start of production, 8 to 9 years after planting into the high yield at the same time, the crown has Since then, the yield is reduced with the decline of the tree vigor. The high yield can not be obtained in the early and late stages, so the planting density is not ideal.
