Abstract:

The relationships between growth status, chemical components in stalks of Neosincalamus affinis and soil fertility in 12 towns of Ya’an were studied in this paper. The results showed that soil total N content was extremely significantly correlated with the contents of soil organic matter, and soil pH value was significantly correlated with the total K content. The wall thickness and the height of biennial stalk were significantly correlated with the content of soil total N while the biomass of biennial stalk were extremely significantly correlated with it. Significant correlations were also found between height of biennial stalk, biomass of 1 to 2 years old stalk and contents of soil organic matter. Both soil total N content and content of soil organic matter were significantly correlated with ash content of biennial stalk, but no significant correlation was found for the lignin content and the total cellulose content. The results may provide important reference for the regional bamboo plantation management.
