【摘要】 采用基质与水提液栽培试验对冬青栎林下的土壤基质对冬青栎种子萌发的影响进行了研究。结果表明,冬青栎林的土壤对冬青栎的种子萌发的抑制作用主要来自枯枝落叶的A00层与A0层。石灰岩基质上的抑制作用与酸性岩基质的抑制作用有差异。酸性岩土壤是对冬青栎种苗更新的安全立地。

【Abstract】 The effect of soil under Hoim oak coppice in the aeid and limestone substratum on germination of Holm oak was studied on both substratum and water-extract tests. The soil under Holm oak coppiee could inhibit the germination of Holm oak and the inhibition was maimly from litter Aoo and Ao. The inhibition effeet of seed germination and seedling establishment of Holm oak in limestone substratum was different from that in the aeid substratum. The soil in aeid substratum is thus considered as a more "safe site"for seed regeneration or seeding establishment of Holm oak than that in limestone.
