提高油茶苗木分枝能力技术研究

Study on the Technology for Improving Bifurcation Ratio of Camellia oleifera Seedlings

本文开展提高油茶苗木分枝能力技术研究,对2年生油茶嫁接苗生长期控高短截矮化修剪处理后,油茶苗木可萌蘖大量分枝,同一品系分枝率差异显著,有的品系对控高处理技术反应不敏感。春梢控高短截后萌蘖分枝能力最强,不同品系间对控高技术的反应具有较大差异。油茶苗木分枝能力与苗木密度和各品系自身分蘖能力有密切关系。

In order to obtain higher bifurcation ratio of Camellia oleifera seedlings, short pruning technique was applied, and the result showed that this technique increased significantly the branch number of the seedlings, with different degrees of effect for different clones; pruning of the spring shoots had the best result; branching capacity was closely related to the density of seedlings and the filleting capacity of the specific clone.
