油茶丰产培育试验研究

Experimental Study on High Yield Cultivation of Camellia oleifera Abel.

摘要:

摘要：通过对不同产量类型的油茶林分树冠及根系结构的比较分析，研究油茶丰产林分具有的生物学特性。结果表明：丰产油茶林分与低产林相比，树高和冠幅的变幅大，树冠绿叶层厚，根系分布深。所以在经营管理时，可通过修剪使树冠呈球形以增加营养空间，多留内膛枝增加绿叶层厚度，深翻和深施肥把根系引向下层，促进油茶丰产。

Abstract:

Abstracts:the crown and root structure are comparative analyzed of different yield and type of Camellia oleifera Abel.stand which had biological characteristics. The results showed that Comparison of high yield and low yield of its stand, tree height and crown width changed larger, green leaf layer of crown was thick, root distribution was deep. so in the management, we can be pruned to make crown spherical in order to increase the nutrition space, keeping more internal branches to increase the green leaf thickness, deep plowing and deep fertilization, and promote the its yield.
