摘要
本文运用典型相关分析的原理及方法,研究了油茶产量结构因素、叶部因素、树体形态因素、土壤肥力因素等4组因素与油茶产量的相互关系。分析结果表明,这4组因素都与产量有显著相关。依据林分产量——密度数量关系,确定了最适栽培密度,并提出了丰产林分的若干营养生长指标。
The correlation of the yield by oil camellia (Camellia oleifera) with the influencing factors of output structure, leaf density, tree form and soil fertility is studied with type correlation analysis. The results indicate that the bearing of fruits is closely linked with each of the four affecting elements. A further study of the interaction of density on stand productivity has enabled the optimal spacing to be singled out, on which various vegetative growth indices for a high outturn are proposed.
