攸县油茶生物学特性及矮化密植早实丰产的研究

对从湖南引种至浙江的攸县油茶生物学特性进行了系统观察,同时对与果实产量有关的主要性状进行相关分析,并就各种不同造林密度进行了试验,得出冠高(x_1)、冠幅(x_2)与单株产量(y)的回归方程:y=0.048 x_1-4.537;y=0.034 x_2-2.24。结果表明,攸县油茶的最适造林密度为每亩500～950株(即7500～14 250株/ha),以此密度造林可达到早实高产之目的。

Studies on Biological Characteristics and High-Yielding with Dwarfing and Close Planting Systems in Camellia yuhsienensis

In this report a series of biological characteristics in C. yuh-sienensis which was introduced into Zhejiang Province from Hunan Province, was systematically observed. The relationships between fruit yield and major economic characteristics analysed. Various planting densities were tested. Some linear regression equations were established as follows: y= 0.048 x1-4.537; y = 0.034 x2~2.240(y: kg, Fruit yield of individual tree; x1: cm, Crown depth; x2: cm, Crown diameter). According to the different management types, it is suggested that the best planting density for C. yuhsienensis should be 7500~14250 trees/ha to achieve high-yielding.
