竹子长两米高了,郁郁葱葱,是挺好看的。邻居找我谈了回话,要我杀灭竹子。说怕竹根长他家房底下去,破坏地基。说会长到后院去,一发不可收拾。我说考虑考虑。我这小块地离他房子约两米,中间隔着我的半高的砖墙。本来想砖墙也有地基的,应当过不去。他那边就是砖铺地。长到后院去,我觉得不大可能的,后院隔了一米多高挡土砖墙,竹子还能跑过去?
既然人家提出来了,还就得有所动作。我先挖了挖,截了60厘米竹根出来。长的挺浅的,在土下只十来厘米深。
网上搜了搜怎么防止跑根,http://www.abc.net.au/gardening/stories/s2557620.htm
看来还是要在种的地方埋一圈阻隔竹根生长的材料(ROOT BARRIER)。要么就每隔半年挖一回,切断长出去的根并刨出来。
How to manage running bamboo:
• You can put down a root barrier, but black plastic isn’t effective. Use specifically made root barrier from a hardware store. To install the root barrier, you first dig a trough around the bamboo planting. The depth you have to go to will be dependent on the size of the bamboo when it’s mature. If your bamboo is one and a half metres or less, then you could probably go down about sixty centimetres. But if you’ve got one of the giant bamboos, something up to even thirty metres, you would have to go down to 1200 centimetres. Put the barrier in the hole and backfill.
• As an alternative to a root barrier, you can, once or twice a year, depending on the vigour of the bamboo, dig down to the rhizomes the whole way around the clump, cut them off and pull them out.
After that your bamboo should stay in order for at least six months.
Stephen explains his preference for severing the rhizomes of his running bamboo, "While root barriers are a great idea, and vital if close to a boundary fence, it’s easy to get lulled into a false sense of security because the rhizomes may still go under, or even over the guard if you’re not vigilant. Mine stay fairly shallow because my well prepared soil is quite shallow and sits on a heavy clay base. In sandy soils, they will go substantially deeper, and so must you." |
