摘要:

以细颗粒(直径<1 mm,T)和粗颗粒(直径1~3 mm,C)马占相思树皮为材料,利用市售酵素菌(J)、有机肥发酵菌(Y)、金宝贝(B)3种菌剂进行发酵,研究其发酵后树皮的理化性质及对‘扬州圆’白萝卜生长的影响,旨在为马占相思树皮资源化利用提供科学依据。结果表明,添加菌剂腐熟的马占相思树皮能促进测试萝卜的生长,树皮有效磷与速效钾含量均以CJ最高,分别为57.60、775.50 mg/kg,且显著高于其他处理。酵素菌处理的树皮上生长的‘扬州圆’白萝卜株鲜重和株干重最高,其次为金宝贝、有机肥发酵菌,且其‘扬州圆’白萝卜全磷与全钾含量均最高,分别为3.95、45.20 g/kg。3种菌剂中以酵素菌处理的马占相思树皮腐熟效果最佳,适宜作为基质使用。

Abstract:

Three kinds of commercial microbial inoculants including enzyme bacteria (J), organic fermenting bacteria (Y), gymboree (B) were employed to ferment fine-grained (diameter <1 mm, T) and coarse-grained (diameter 1-3 mm, C) Acacia mangium bark to prepare substrates, and the physicochemical properties and the influence on the growth of white radish ‘Yangzhouyuan’ were investigated, in order to provide a scientific basis for utilization of the bark of A. mangium . The results showed that the bark supplemented with the bacterial agent could promote the growth of radish. The content of available phosphorus and available potassium in the substrate was the highest, which was 57.60 and 775.50 mg/kg, respectively, and significantly higher than that of other treatments. Whole plant fresh and dry weight of white radish ‘Yangzhouyuan’ grown on the substrate treated with enzyme bacteria was the highest, followed by gymboree and organic fermenting bacteria. The content of total phosphorus and potassium in the white radish ‘Yangzhouyuan’ was the highest, which was 3.95 and 45.20 g/kg correspondingly. The results suggest that the bark of A. mangium treated with enzyme bacteria had the best effect, and was suitable to be used as a substrate.
