近几年来,各地普遍开展了柑桔密植试验,有的已取得一定的成绩。但是在大面积生产上仍然存在如何获得早产、丰产、稳产以及如何提高劳动生产率和降低生产成本等问题。为了摸索密植栽培的主要技术措施,作者于1977～1984年间在四川邻水县板桥公社果园,兴仁玻璃马峰果园等地进行了密植丰产的调查与试验研究。对于中密度(120～180株/亩)枳砧锦橙山地的计划密植,提出以下几点看法。
In recent years, citrus close planting has been widely carried out in various places and some achievements have been made. However, in large-scale production, there are still some problems such as how to get premature birth, high yield, stable production and how to improve labor productivity and reduce production costs. In order to explore the main technical measures of close planting cultivation, the author conducted a survey and experimental study on close planting and high yield in Banqiao commune orchards, Xingren glass Mafeng orchards in Lishui County, Sichuan Province from 1977 to 1984. For medium density (120 ~ 180 plants / acre) orange angelica Jin orange mountain dense planted, put forward the following views.
