摘要: 通过对雅安地区12个乡镇慈竹生长状况及竹材成分与林地土壤肥力关系的研究,结果表明:雅安地区土壤有机质含量与全氮含量存在极显著相关,土壤pH值与全钾含量存在显著相关;土壤全氮含量与2年生慈竹的壁厚、竿高显著相关,与2年生慈竹竿重极显著相关;土壤有机质含量与2年生慈竹的竿高和1、2年生慈竹的竿重都存在显著相关;土壤全氮含量与有机质含量会显著影响2年生慈竹竹竿灰分的含量,但对木质素含量和综纤维素含量的影响不显著。

Abstract: The growth status, chemical components in stalks of Neosincalamus affinis and their relationship with soil fertility were investigated in 12 towns of Yaan, China.Significant relationships were observed between soil N content and soil organic matter content, and between pH and soil K content.Wall thickness, the biomass of biennial stalk and the height of biennial stalk were significantly correlated with soil N content.Additionally, the height of biennial stalk, and the biomass of 1 to 2 years old stalk were correlated with soil organic matter contents.Although ash content of biennial stalk were significantly correlated with soil total N content and soil organic matter content, little correlation was detected between the lignin content and the total cellulose content.The results could provide important data for the management of regional bamboo plantation.

Key words: Neosincalamus affinis, soil fertility, growth, lignin, total cellulose, ash
