毛竹笋竹两用林培育技术措施探讨

Approaching the Cultural Technical Measures of Phyllostachys heterocycla Forest Used for Both Bamboo Shoot and Bamboo

按照分类经营的办法,进行毛竹笋竹两用林培育技术措施的试验示范,经过3a时间,平均立竹密度从试验开始时的底竹1602株·hm-2,提高到2865株·hm-2,增加了78 8%,胸径从原来的7 4cm提高到9 7cm,增加了31%,投入产出比为1∶2。

The experimental demonstrations of cultural technical measures of Phyllostachys heterocycla forest used for both bamboo shoot and bamboo were conducted by the way of classification management,through 3 years,the present average living bamboo density increased to 2865 trees per hm2 from 1602 trees per hm2 when the experiment began,and increased by 788%,dbh increased to 97cm from former 74cm,and increased by 31%,the ratio of input to output was 1∶2.
