菌根多样性对红楮林细根生物量及红菇采收量的影响

Effect of mycorrhizal biodiversity on fine root mass of Cyclobalanopsis chungii and basidiocarp collection of Russula vinosa.

试验研究菌根多样性对红楮林细根生物量及红菇采收量的影响结果表明，处理区菌根菌种类增加11个，红菇产量增加11．25kg／hm^2，增幅68．18％，差异显著；0～100cm土层细根生物量增加3．35t／hm^2，差异显著；0～10cm土层细根生物量增加3．26t／hm^2，增幅190％，差异极显著。表明人工促进菌根多样性不仅提高了森林生态系统中的乔木细根量，还提高了菌根菌的丰度和频度。

The experiment on mycorrhizal inoculation in pure stand of Cyclobalanopsis chungii disturbed by intemperate mushroom collection was conducted to study the effects of mycorrhizal biodivcrsity on fine root mass oF Cyclobalanopsis chungii and basidiocarp yield of Russula vinosa. Results show that mycorrhizal species found in the treatments surpasses the contrast by 11. Total basidiocapes of Russula vinosa are 11.25kg/hm^2 higher and fine root mass in 0 -- 100cm and 0 10cm soil core 3.35t/hm^2, 3.26t/hm^2 higher than those of the control significantly. It is concluded that mycorrhizal biodiversity improves fine root mass and enhances the abundance and frequency of mycorrhizal basidiocarp.
