摘　　要：对不同类型的天然油茶低产林以不同截干高度和不同截枝修剪方式,对老龄油茶树进行更新改造试验。结果表明:油茶树体截干和截枝更新对油茶产量均有提升作用,其中截干高度为50~70 cm的效果最好。针对树体开张、冠幅较大的油茶树型适于采用1/3主枝截枝的修剪方式;对于直立茂密、冠幅较小的油茶树,以全部主枝截枝的方式,更利于开花结实,提高产量。Different types of natural camellia camellia were tested with different cutting height and different pruning methods.The results showed that both the trunk removal and branch removal and regeneration improved the yield of camellia oleifera,with a best interception height of 50-70cm.For camellia trees with tree opening and large crown,1/3 of the main branches are cut off,it is more conducive to blossom and strengthen and increase the yield.
