摘要
在福建省邵武市对椽竹、孝顺竹、坭竹等几种造纸用丛生竹进行秆节育苗试验表明，用平埋方法育苗显著优于斜埋和直插，竹蔸平埋效果更佳；不同竹种秆节育苗成活率存在明显差异；不同年龄的秆节育苗成活率在不同竹种间表现不同；不同育苗时间（３月或５月）的成活率差异不显著。竹秆不同粗细、不同部位、单节段或双节段育苗对比试验，结果以细秆（胸径２．５ｃｍ）、上部节段、双节段育苗成活率较粗秆（胸径４．６ｃｍ）、下部节段、单节段的为高。椽竹秆节径用不同激素处理后，处理间成苗率差异显著，以２，４－Ｄ２０ｍｇ／ｋｇ处理５ｈ和硼酸２０ｍｇ／ｋｇ处理２４ｈ的效果最佳。
The seedling culture test with node of such sympodial bamboo species for pulping as Bambusa textilis var. fasca Macclure, B. multiplex (Loun) Racuschel ex Schut f.and B.gibba Macclure suggested that within burying methods the flat burying is better than the slant or vertical ones with the best effect of flat burying of bamboo stump. There is significant difference between different bamboo species in seedling culture survival rates with bamboo node,that survival rates differ in node age, and there is no significant difference between different seedling growing seasons(March or May).The seedling culture test with different thickness,position,single or double internode suggested that survival rates with thinner culm( 2.5 cm in diameter),higher position and double internode are better than those with thicker culm(4.6 cm in diameter),lower position and single internode.The survival rates differ between hormone treatments with the best effects of 2,4 D( 20 mg/kg,5 h) or boric acid(20 mg/kg).
