菌根菌与益生菌组合对桉树苗木生长的影响
Effect of mycorrhizal fungi combined with probiotics bacteria on the growth of eucalyptus seedlings
摘要
Abstract
[Objective]The effects of mycorrhizal fungi and probiotic combination on the growth of eucalyptus seedlings were studied and the effects of probiotics on the growth of eucalyptus seedlings were investigated. [ Method ] Using puffball fungi combined with phosphate-solubilizing bacteria, nitrogen-fixing bacteria, and potassium bacteria, the tissue cultures of eucalyptus seedlings were inoculated. After seedling culture for 3 months, the nursery mycorrhizal infection rate was examined and the seedling height, ground diameter, and biomass were measured according to the method of completely randomized sampling design. [Result]Using the 11 probiotics combined inoculations as test subjects, after seedling culture for 3 months, the eucalyptus seedlings mycorrhizal infection rate was between 70%-90%. Three months after inoculation , the seedling height increased by 22.95%-64.40% compared to that of the control group, the ground diameter increased by 23.53%-61.18% compared to that of the control, and the biomass (dry weight) increased by 7.72%-98.15% compared to that of the control. The seedling height, ground diameter, and biomass measured under each treatment were significantly different from those of the control group. [Conclusion]Different probiotics had different degrees of promotional effects on eucalyptus seedling growth, of which the 6 probiotics combinations, Z-3, Z-5, Z-8, Z-4, Z-2, and Z-11 , were especially effective in eucalyptus growth promotion and could be used as the eucalyptus strain combinations with excellent growth effects.关键词
