  • Five different fertilizer treatments were applied to investigate their effects on soil nutrients,soil enzyme activities,soil microbial populations and growth of Dendrocalamus sinicus seedlings. The fertilizer recipes were as follows:inorganic fertilizer 1 (A:N-P-K ratio of 22:8:15 and total effective nutrient content ≥ 45%);inorganic fertilizer 2 (B:N-P-K ratio of 16:16:16 and total effective nutrient content ≥ 48%);organic fertilizer (C:fermented pigeon manure);green manure (D:Vicia villosacv.varglabrescens);and no fertilization control:CK. The results showed that soil nutrients,soil enzyme activities,soil microbial populations and plant biomass under all fertilizer treatments were higher than those in control group,with data in C being the highest among all treatments. Soil nutrients were positively correlated with fungi,nitrogen-fixing bacteria and above-ground biomass,and negatively correlated with bacteria and actinomycetes. The above-ground biomass of bamboo seedlings demonstrated positive correlations with soil nutrients,catalase,acid phosphatase,urease,fungi and nitrogen-fixing bacteria,and negative correlations with bacteria and actinomycetes. The correlations between branch fresh weight and hydrolysable nitrogen and fungi were highly significant (P<0.01),and the correlations between branch fresh weight and total nitrogen,total phosphorus,available phosphorus and nitrogen-fixing bacteria were significant (P<0.05). The correlation between culm fresh weight and acid phosphatase was significant. In general,the soil quality was ranked as C>D>B>A>CK,and treatment C had the largest positive impact on soil quality while the effect of treatment A was weakest.
