摘　　要：本文通过对箬竹林施用不同竹加工剩余物和竹炭比例的混合肥料,研究其对箬竹林地土壤养分、微生物酶和竹叶的影响。结果表明:施用竹加工剩余物和竹炭混合物显著提高了箬竹林地土壤有机质、全氮、有效磷、有效钾和有效硅含量,显著降低了酸性磷酸酶含量,显著提高了蔗糖酶含量,显著增加了箬竹叶长和叶宽(P<0.05)。处理7较CK分别增加叶长和叶宽28.57%和80.00%,说明70%竹加工剩余物与30%竹炭混合物共同作用于箬竹林土壤能有效保留和提高土壤养分含量,改善土壤性状,满足箬竹对土壤养分需求,有效提高箬竹生产力。The mixed fertilizers with different proportions of bamboo processing residues and bamboo charcoal were applied to Indocalamus hunanensis forest to study the effects of mixed fertilizers on soil nutrients,microbial enzymes and bamboo leaves of Indocalamus hunanensis forest.The results showed that the application of bamboo residues and bamboo charcoal mixture significantly increased the soil organic matter,total nitrogen,available phosphorus,available potassium and available silicon.Moreover,the mixture also significantly decreased acid phosphatase,significantly increased the content of invertase,the leaf length and width of Indocalamus hunanensis(P<0.05).Compared with CK treatment,the leaf length and leaf width were increased by 28.57%and 80.00%in treatment 7,respectively.The results indicate that the combined action of 70%bamboo processing residues and 30%bamboo charcoal mixture can effectively retain and increase the soil nutrient content of Indocalamus hunanensis forest.The mixture could improve the soil properties,meet the demand of Indocalamus hunanensis for soil nutrients and effectively improve the Indocalamus hunanensis production.
