【摘要】 对麻栎幼林开展施肥试验。结果表明:施用微生物有机菌肥与化肥对麻栎树高生长有显著影响,其中施用微生物有机菌肥2 kg·株^-1+尿素2 kg·株^-1对麻栎树高增长效果最好,施肥1年3个月后树高增长量为2.31 m;微生物有机菌肥与化肥施肥量配比对麻栎胸径生长有显著影响,施用微生物有机菌肥1 kg·株^-1+复合肥2 kg·株^-1和微生物有机菌肥2 kg·株^-1+复合肥2 kg·株^-11年3个月后,胸径增长量分别为0.99 cm和0.89 cm,均显著高于施用其它配比肥的。增施复合肥更有利于麻栎的均衡生长,而微生物有机菌肥是缓效性肥料,对改善土壤理化性质和增加土壤活性有益。更多还原

【Abstract】 The fertilization experiments was based on young forest of Quercus acutissima.The results showed that the application of microbial organic bacterial fertilizer and chemical fertilizer had a significant effect on the height growth of Q.acutissima height, the application of microbial organic bacterial fertilizer 2 kg per plant + urea 2 kg per plant had the best effect on the height,which increased by 2.31 m after 1 year and 3 months of fertilization.The ratio of microbial organic bacterial fertilizer and chemical fertilizer has significant effect on the DBH growth of Q.acutissima.The increment of DBH was 0.99 cm and 0.89 cm after(1 year and 3 months) when applying microbial organic fertilizer 1 kg per plant +compound fertilizer 2 kg per plant and microbial organic fertilizer 2 kg per plant+compound fertilizer 2 kg per plant, respectively, which were significantly higher than that of other fertilizers.Adding compound fertilizer is more conducive to the growth of Q.acutissima, while microbial organic bacterial fertilizer is slow-acting fertilizer, which is beneficial to improving soil physical and chemical properties and increasing soil activity.更多还原
