송이 균환의 발달에 따른 토양의 이화학적 특성과 탈수소효소의 활성 변화

The management of pine-mushroom forest means the environmental control for fairy ring of Tricholoma matsutake. Thus, the management demands intensive study for keeping healthy condition of the fairy ring, and that for the measurement of active portion of the soil ecosystem. This study was conducted to investigate the impact of T. matsutake fungus on the soil physicochemical properties and dehydrogenase activity by dividing the fairy ring into 3 regions such as `zone of decayed mycorrhizae`, `zone of physiologically active mycorrhizae`, and `in front of fairy ring` . The passing of T. matsutake did not result in significant changes in canon contents of soils, but available phosphorus, carbon, and nitrogen contents were different between the soils of active mycorrhizal zone and that in front of fairy ring. The dehydrogenase activity around the fairy ring of T. matsutake was quite lower than that in general forest soils, which indicated that the fairy ring of T. matsutake was built up in the relatively immature soils which contain little organic matter. Thus, the dehydrogenase activity of soil was thought to be used as an index for the management of pine-mushroom forest with considering that the management practically means the environmental control for keeping good conditions for the development of fairy ring of T. matsutake. Especially, the dehydrogenase activity measurement can be recommended as a tool for time-decision of litter removal by floor raking since the activity is a good index of litter decomposition.

The object of this study was to analyze influence which Black locust afforestation affected to soil, to research change of soil environment of Black locust planted stand and adjacent stands through comparative analyzing physichemical property of soil of them. It was investigated that the soil texture of Black locust planted stand and the adjacent stands was mostly SL and LS. According to this result I could know that transformation of soil texture by vegetation easily happened because transformation soil texture results from the parent rock. I could ascertain that difference existed between Black locust planted stand and the other stands in soil pH and Carbon content of planted stand of Black locust pH, contents of Available P_(2)O_(5), Carbon, Total Nitrogen. In other words, pH and Carbon content of Black locust planted stand were lower than that of Oak forest, higher than that of Pine forest. These results showed that Black locust was which fix nitrogen. I could infer that Black locust afforestation made forest soil fertilized. In soil of Black locust planted stand and the adjacent stands, statistical value appeared highly in pH and existed in content of Carbon, Total nitrogen, too. And high interrelationship appeared in the order of pH, C/N Ratio, CEC, Total nitrogen content was in each stands. I suppose that the trespassing extent of Black locust to Oak forest and Pine forest which are adjacent to planted stand of Black locust is different because of low pH, lackness of Available P_(2)O_(5), Carbon, and what not.
