摘要
对桉树伐桩进行萌芽控制试验 ,结果表明 :采用 4 1%草甘膦除草剂 10ml/L液喷 30～ 6 0cm高的伐桩萌芽条 ,萌芽条和伐桩死亡率达 95 %以上 ;伐桩萌芽前采用厚度 2C以上的黑色塑料袋覆盖 ,可以控制伐桩萌芽 ,伐桩死亡率达到 82 .7%以上。以上两种方法控制桉树伐桩萌芽效果好 ,操作方便 ,费用低 ,可以在桉树林抚育间伐、低产林分改造和采伐更新换代造林中推广使用。
The sprout control test of Eucalyptus stumps was ca rr ied out in Xijiang Forest Bureau, Zhaoqing city. The results showed that the dea th rate of sprouts and stumps is up to 95% by spraying 10 ml/L of 41% Glyphosat e herbicide on the sprouts with 30～60 cm high.
