摘要: 通过盆栽对比试验,对酸性土和石灰土上生长的滇青冈和元江栲幼苗的生长特征进 行研究。结果表明:红色石灰土上滇青冈和元江栲幼苗生长均受到抑制,两种植物幼苗在黑色石灰土上均生长良好;黑色石灰土上滇青冈幼苗根 生物量比显著提高,而叶生物量比降低,根冠比显著高于酸性土和红色石灰土上植株的根冠比;红色石灰土上元江栲幼苗叶片的叶绿素和类胡萝卜 素含量显著低于酸性土和黑色石灰土上的植株的相应值;在3种土壤条件下元江栲幼苗各部分的生物量分配没有显著差异。

Abstract: Through parallel trials, the growth characteristics for seedlings of Cyclobalanopsis glaucoides and Castanopsis orthacantha grown in three different soils were studied. The results showed that:the growth of C. glaucoides and C. orthacantha were significantly different between acidic soil and red calcareous soil after a growth season. The increment of height, stem basal diameter and leaves of C. glaucoides and C. orthacantha were significant in acidic soil comparing to those in red calcareous soil. Seedlings of two species all grew better in black calcareous soil. The RMF of C. glaucoides in black calcareous soil were higher than those in acidic soil and red calcareous soil, then the R/C increased notably in black calcareous soil while the LMF decreased. In three different soils, the R/C, RMF and LMF of C. orthacantha were all of no significant difference. The content of chlorophyll and chlorophyll a/b of C. glaucoides had no obvious difference in three different soils, but the content of carotenoid in black calcareous soil and red calcareous soil was lower significantly than that in acidic soil. The content of chlorophyll and carotenoid of C. orthacantha seedlings grown in red calcareous soil were notably less than those in black calcareous soil and acidic soil. The chlorophyll a/b in seedlings of C. orthacantha grown in two calcareous soils was significantly higher than those in acidic soil.
