岑软3号油茶无性系树高、冠幅与产果量关系的研究

摘要

采用显著性分析、偏相关分析及回归分析研究岑软3号油茶无性系树高、冠幅与产果量的关系.结果表明:树高和冠幅显著影响产果量,其中冠幅对单株产果量影响较大;冠幅与树高呈极显著正相关关系;单株产果量随着冠幅及树高的增大而增加,树高达2.5 m后不同树高植株间产果量差异不显著;得出通过树高、冠幅预测单株产果量的回归方程,表明在保证合理树高的条件下,积极培育冠幅可显著提高油茶产果量.%Based on the significance analysis,partial correlation analysis and regression analysis,authors studied the relationship between the tree height,crown width and the yield of C.oleifera Cenruan 3 clone.The results showed that the tree height,crown width significantly affected the yield per plant of C.oleifera,and the crown width showed a greater role;There was a highly significant positive correlation between the tree height and the crown width;The yield per plant of C.oleifera increased with the increase of the crown width and tree height.When the tree height ＞2.5 m,there was no significant difference between the yield of different plants;The regression equation of yield was predicted by the tree height and crown width,it showed that under the condition of reasonable tree height,promoting the crown width can significantly increase the yield of C.oleifera.
