摘要

采用温室盆栽实验与人工造林地表覆盖试验方法，研究不同覆盖材料下的土壤蒸发特性、土壤保墒能力及苗木生长状况。结果表明：在土表覆盖条件下土壤含水量较对照(CK)有不同程度提高；在水稻秸秆覆盖下冰脆李、栾树林地土壤含水量较对照(CK)分别增加13.86%和9.82%；在玉米秸秆覆盖条件下梓树林地土壤含水量较对照(CK)增加7.79%；土表覆盖措施对苗木根质量和叶面积影响显著而对苗高影响不显著。喀斯特地区人工造林采用地表覆盖措施可减轻高温对苗木的伤害及季节性干旱对幼林生长的影响，从而提高苗木生物量。因此，地表覆盖可作为喀斯特地区人工造林初期促进植被恢复的有效措施之一。

Abstract

Effects of different mulching materials were studied by means of pot culture and open-field experiments on soil evaporation, soil temperature and seedling growth. Main results were described as follows: (1) Compared to CK, soil water content of Prunus salicina and Koelreuteria paniculata under the rice straw were increased 13.86% and 9.82% respectively. (2) Soil water content of Catalpa speciosa cv.was increased 7.79% under the corn straw. (3) The effects of mulching measures were significant on root weight and leaf area, but not obvious to seedling height. Mulching could reduce the damage to seedlings caused by high temperature and seasonal drought and increase their biomass. Therefore, it could be used as one of measurements to promote vegetation restoration at the early establishment of plantation.
