苦竹林分结构对鲜笋产量的影响分析

The Influence Analysis of Bamboo Stand Structure on the Bamboo Shoot Yield of Pleioblastus macutatus

  • 摘要: 苦竹是川南地区优良的笋用竹种。本研究比较了不同年龄结构、胸径结构,以及林分密度3个因子下苦竹的产笋能力差异。结果表明:年龄结构、林分平均胸径、立竹度对苦竹鲜笋产量均有显著的影响,而胸径整齐度对苦竹鲜笋产量影响不显著。其中1年生+2年生+3年生竹龄主导型的竹林产笋能力最好,鲜笋产量达4 770 kg·hm-2,发笋数达13 900个·hm-2;平均胸径6 cm的竹林鲜笋产量最高,达到4 580 hm2;立竹度10 000~12 000株·hm-2的竹林产笋能力最好,鲜笋产量达4 700 hm2,发笋数达1 550 hm2。结合各因子来看,以1、2、3年生竹竹龄主导型+中大的林分平均胸径(4~6 cm)+中等立竹度(10 000~12 000株·hm-2)的苦竹林鲜笋产量最高,是比较理想的苦竹林分结构。

     

    Abstract: Pleioblastus maculatus is one of the most excellent shoot-used bamboos in south Sichuan. 3 stand factors(age structure, DBH structure and bamboo density) were chosen to analyze the influence on bamboo shoots. The results showed that there were significant influence between 3 stand factors and bamboo shoots, and no significant influence were found between DBH uniformity and bamboo shoots. One year, two years and three years old dominant stands were found to be the better age structure with a highest shoot yield (4 770 kg·hm-2) and shooting number(13 900 hm2); 6cm DBH stand was found to be the better DBH structure with a highest shoot yield(4 550 hm2); 10 000~12 000 hm2 were found to be the better stand density with a highest shoot yield(4 700 kg·hm-2) and shooting number(15 500 numbers·hm-2).In conclusion, the ideal stand structure was found to be composed of dominant age of 1 year+2 year+3 year, DBH of 4~6cm, and medium stand density(10 000~12 000 numbers·hm-2).
