我省温州蜜柑的栽植密度,六十年代前一般亩栽30—40株,七十年代红壤丘陵山地大力发展了柑桔生产,密度普遍增加到每亩60株以上,并注意早结丰产的问题。为了研究其栽培技术,1973年我们在本所红壤丘陵山地开展了密植、早结、丰产试验,以期达到3年结果、5年丰产并持续丰产的目的。 The planting density of Satsuma mandarin in our province was 30-40 mu in the first half of the 1960s. In the seventies, the production of citrus was greatly promoted in the hilly red soil region. The density generally increased to more than 60 plants per acre and attention was paid to the problem of high yield early . In order to study its cultivation techniques, we conducted a close planting, early knot and high yield experiment in the hilly red soil region in 1973 in order to achieve the result of 3 years, 5 years of high yield and continued high yield.
