一、前言 .七十年代末,浙江省江山县从外地调入大批温州蜜柑苗以发展柑桔生产。至今,大多数5～6年生的柑桔,开花很少或不开花,即使开花,座果率也很低。其原因系大多数砧木为非枳砧,主要为香橙(Citrus junos)中的蟹橙和酸橙(Citrus aurantium)中的构头橙。与枳壳砧温州蜜柑相比,表现生长势强健,枝条直立,投产迟。
First, the foreword The late seventies, Zhejiang Jiangshan County transferred from the field a large number of Wenzhou Satsuma to develop citrus production. To date, most citrus fruits, aged from 5 to 6 years, have little or no flowering and even low flowering rates. The reason for this is that most rootstocks are not Trifolium oranges, mainly crab oranges and citrus aurantium in Citrus junos. And Citrus aurantium orange mandarin compared to the performance of strong growth potential, upright branches, put into operation late.
