室外调查结果表明,华南地区的桉树菌根虽然较贫乏,但仍发现有9种外生菌根真菌。在平均气温20℃以上,相对湿度80%以上及有相当降雨量的条件下,菌根菌子实体可大量产生;不同立地条件对外生菌根的分布有密切关系。使用5种不同的接种方法对桉树幼苗进行接种,均有较好的接种效果,其中,VA 菌根土接种,孢子菌剂接种,罐栽菌木接种及 Mycobeads 接种均有较好的效果,而且方法简单,使用方便。一年生桉树接种苗比对照株高生长平均增加14.3%;胸径平均增加13.67%;处理区一年生幼树蓄积比对照区每公顷增加5.12m~3,增加39.9%,投入与产出比为1∶15。
According to the outdoor investigation, eucalyptus mycorrhizae in southern China was found to be emaciated, but nine ectomycorrhizal fungi were still found. Under the conditions of average temperature above 20 ℃, relative humidity above 80% and considerable rainfall, mycorrhizal fruiting bodies can be produced in large quantities; different site conditions are closely related to the distribution of ectomycorrhiza. Five different inoculation methods were used to inoculate Eucalyptus seedlings, which showed good inoculation effect. Among them, VA mycorrhizal inoculation, spore inoculation, inoculation inoculation and Mycobeads inoculation all had good effects, and The method is simple and easy to use. Annual growth rate of eucalyptus inoculated seedlings increased by 14.3% compared with that of the control; the average diameter at breast height increased by 13.67%; the annual seedling accumulation in treatment area increased 5.12m ~ 3, increased by 39.9% 15.
