摘要: |
利用正红菇和鳞盖红菇2个菌种,对木荷、红锥和黎蒴3个乡土树种的苗木进行接种试验,定期观测苗木的苗高、地径及最终生物质量。结果表明两个菌种对3个乡土树种的苗期生长均有明显的促生效果。接种270d后,3个树种接种处理苗期的苗高、地径、地下干质量和地上干质量等生长指标均明显优于未接种对照苗的各生长指标。方差分析结果表明,接种红锥苗的苗期各生长指标极显著优于未接种对照苗;接种黎蒴和木荷苗期的各生长指标与未接种对照苗有明显差异。菌根感染强度及依赖性分析结果表明,红锥的感染强度为4级,属强依赖性;黎蒴与木荷的感染强度为2级,属弱依赖性。红锥树种可与两个红菇菌形成较佳的共生体,其中以鳞盖红菇的接种效果为最佳。 |

The effect of seedling inoculation of three local tree species inoculated by Russula lepida and R.vinosa |

Abstract: |
The seedling height, ground diameter and biomass were measured at regular intervals after two strains, Russula vinosa and R. lepida, were inoculated to the roots of Castanopsis hystrix, Schima superba and Castanopsis fissa. It was showed that the two strains significantly improved seedlings growth of three inoculated tree species. About 270 days intervals, the seedling height, ground diameter and biomass of seedlings inoculated were higher than that of un-inoculated seedlings among three species. Analysis of variance indicated that there was a extremely significant difference in inoculated and control seedlings of C. hystrix while those of S. superba and C. fissa showed obvious difference. Analysis of mycorrhizal infection and dependence suggested that C. hystrix was strongly depended on the two strains, while S. superba and C. fissa showed moderate dependence. The optimal effect was seedlings of C. hystrix inoculated by R. lepida. |
