| Abstract: | 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 behind 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,fertilization,economic benefit is up to 17 928 yuan /hm2annually; by taking tending measures of irrigation and fertilization,economic benefit is up to 52 860 yuan /hm2annually. Benefit of Dendrocalamus Giganteus has been greatly improved; the amount of bamboo shoots is little without tending. |
