油桐是一种生长快,一般三四年就有收益的经济林木,但产量低。为了尽快地提高产量,我们从一九八五年起对油桐栽培技术的有关问题进行了初步的摸索,现简介如下: 一、造林地坡位的选择疏松、深厚、肥沃、湿润且排水良好的土壤,利于油桐生长。而土壤肥力与水分状况和一定的坡位、坡度等有关系。经调查,同一向阳的山凹地四年生油桐树, Tung is a kind of fast-growing, usually three or four years have the benefits of economic trees, but low yields. In order to increase production as soon as possible, we have made preliminary exploration on the related problems of tung tree cultivation technology since 1985. The brief introduction is as follows: 1. The choice of slope position in afforestation land is loose, deep, fertile, moist and well-drained The soil is conducive to the growth of Tung Oil. Soil fertility and water status and a certain slope, slope and so on. After investigation, the same sunny mountain four years Tung oil tree,
