摘要
通过对油茶优良无性系进行不同程度的修剪试验发现,修剪对油茶产量均有不同程度的促进作用．树体开张茂密的树形经中度修剪,产果量的增长幅度为107．2%;树体直立茂密的树形经重度修剪,增产达99．4%．油茶树体修剪,对油茶成林果实主要经济性状也产生一定的影响,中度和重度修剪可以适当提高鲜果出籽率并使油茶果实增大．结合增产情况,对于树体开张茂密的树形,中度修剪有利,而对直立茂密的树形则以重度修剪较有利．
Tree pruning techniques have been applied on the superior clones in C. oleifera L. , and have positive effects in some extent on the fruiting yield. The fruiting yield of tree with open shape can be raised 107. 2% by Medium pruning, while it of tree with upright shape can be raised 99. 4% by heavy pruning. Tree pruning also has effects on the main economic characteristic of fruit, and medium and heavy pruning can enhance the seed ratio and the volume of fresh fruit.
