通过分类经营,毛竹材用林、两用林和笋用林的竹材和竹笋产量都得到较大提高,从示范基地看,到2012年,材用林竹材和竹笋产量分别达到28 755kg/hm2和3 750kg/hm2,比2008年增长71.2%和13.6%;两用林竹材和竹笋产量分别达到17 265kg/hm2和5 775kg/hm2,比2008年增长65.6%和45.8%,而2010年增长更多;笋用林的竹笋产量,2010年和2012年分别为30 570kg/hm2和23 190kg/hm2,比2008年增长62.9%和23.6%。通过分类经营,可充分发挥不同立地条件的增产潜力,增加竹材和竹笋产量,提高经济收益。因此,在立地条件较好的毛竹林,可通过笋用林经营技术,以提高竹林的经济收益。在立地条件中等的毛竹林,可适当发展两用林,特别在毛竹竹材价格下降的情况下,通过提高竹笋产量,特别是冬笋的产量,可极大提高毛竹林的经济效益。
Through the classified management, bamboo timber and bamboo shoot production of bamboo forest, dual-use forest and bamboo shoot forest have been greatly improved. From the demonstration base, by 2012, the output of timber forest bamboo and bamboo shoot reached 28 755kg / hm2 and 3 750kg / hm2, an increase of 71.2% and 13.6% compared with that of 2008. Bamboo and bamboo shoots yield reached 17 265kg / hm2 and 5 775kg / hm2, respectively, up 65.6% and 45.8% over 2008, but more in 2010 The bamboo shoot production of bamboo shoots was 30 570 kg / hm2 and 23 190 kg / hm2 respectively in 2010 and 2012, an increase of 62.9% and 23.6% over 2008 respectively. Through the classified management, we can give full play to the production potential of different site conditions, increase the output of bamboo and bamboo shoots and increase the economic returns. Therefore, in a well-site Moso bamboo forest, bamboo trees can be used to operate technologies to increase the economic benefits of bamboo forests. Moso-bamboo forests with moderate site conditions can be used for the development of dual-purpose forests. Especially when the price of bamboo bamboo is declining, the economic benefits of Moso bamboo forests can be greatly enhanced by increasing the yield of bamboo shoots, especially that of winter bamboo shoots.
