摘要：通过杉木幼苗的盆栽试验,采用喷施及土壤施入两种施用方法及9个不同浓度处理,分析施用竹酢液后对土壤化学性质以及杉木苗高和地径生长的影响。结果表明:施用竹酢液后,土壤pH无明显变化;H50和P300两种处理可以明显提高土壤全氮和速效磷含量,降低苗木生长过程中土壤速效钾、碱解氮和有机质等指标含量的衰减程度;促进土壤脲酶、多酚氧化酶和过氧化物酶的活性;对苗高和地径的生长有明显的促进作用。总体看来,适宜浓度的竹酢液对提高杉木人工林土壤肥力,促进杉木生长有利,其应用前景广泛。
Pots experiment was conducted to study the effects of bamboo vinegar on soil chemical properties, height and ground diameter of Cunninghamia lanceolata seedlings. The experiments used 9 different concentrations of bamboo vinegar with 2 application methods of spray application and application to the soil. Results showed that the application of bamboo vinegar did not change the pH of the soil among 9 concentrations, H50 （ soil application, diluted bamboo vinegar 50 times） and P300 （spray leaves, diluted bamboo vinegar 300 times） evidently increased soil total N and available P, decreased the consumptioon of available K, hydrolyzable N, and organic matter on growth of seedlings. Bamboo vinegar promoted the activities of soil ureases, peroxidases and polyphenol oxidases, and increased the height and diameter growth of Cunninghamia lanceolata seedlings significantly. In general, bamboo vinegar with suitable concentration can improve soil fertility in Cunninghamia lanceolata plantation and suitable for tree growth and thus has a promising future.
