在新平县古城低产林改造复壮示范林及县城南面山钟楼背后示范林内设置样地观测系列复状技术产生的效果,分析相应经济效益。结果表明:对云南甜龙竹低产竹林采取疏伐老秆、伐桩清理、施肥抚育措施,发笋量比对照提高20%以上;采取扒晒、除蔸、施肥等抚育措施,每年可收益17928元/hm2;采取灌水、施肥等抚育措施,每年可收益52860元/hm2,竹林效益得到极大提高;未进行抚育的竹林发笋量很少。

In order to observee improved effect and economic benefit of the low-yield Dendrocalamus Giganteus forest, sample plot is set up in demonstration forest of Xinping county at the south mountain be-hind the clock tower .Results shows that: by taking tending measures such as thinning old stalks , flat stumping , fertilization , bamboo shoots amounts of low-yield Dendrocalamus Giganteus forest is increased by 20%compared with the control;by taking tending measures of drying in the sun , flat stump, fertiliza-tion, economic benefit is up to 17 928 yuan/hm2 annually; by taking tending measures of irrigation and fertilization, economic benefit is up to 52 860 yuan/hm2 annually.Benefit of Dendrocalamus Giganteus has been greatly improved;the amount of bamboo shoots is little without tending .
