松茸圈扩散与土壤化学元素含量之间的关系

Relationship between Tricholoma matsutake Circle spreading and Chemical Element Contents in Soil

摘要:

在自然条件下,松茸子实体呈环状分布,每年向外扩展一定的距离,形成松茸圈,而圈内成为松茸孢子几年内不能萌发的废弃地。初步研究了松茸圈扩散与土壤中13种化学元素含量之间的关系。结果表明,松茸对Ca、Na、Mg、Mn、Si的消耗较大,且含量恢复较慢,可能是松茸圈扩散的限制因子。

Abstract:

Under natural conditions, Tricholoma matsutake spreads annually as circle shape,so“ Tricholoma matsutake circle”is formed.The soil inside the circle becomes abandoned land where Tricholoma matsutake spore cannot sprout within several years.The relationship between Tricholoma matsutake circle spreading and 13 chemical element contents in soil was studied preliminarily.Ca,Na,Mg,Mn,and Si are consumed in greater amount by Tricholoma matsutake, and restored more slowly.These five elements are the probable limiting factors for spreading of Tricholoma matsutake circle.
