摘要

通过人工模拟试验分析了CO

浓度升高对羊草、针茅的"施肥效应"。结果表明生物量随CO

浓度的升高而增加;总生物量分别增加40.0%和45.0%。土壤干旱对羊草、针茅的生长及干物质积累为负效应且随干旱程度的增加负效应增强。轻度干旱时总生物量分别减少16%和30%左右

严重干旱下降44%和35%左右。在土壤发生干旱条件下

的"施肥效应"有所减弱

羊草比针茅更为明显。

Abstract

Using artificial experiment

the "fertilization function" of CO2 enrichment on Aneurolepidium chinensis and Stipa baicalensis is analyzed.The results showed that the biomass increased with CO2 concentration enrichment

and their total biomass increased by 40.0% and 45.0%.The impacts of soil drought on growth and accumulation of dry matter of Aneurolepidium chinensis and Stipa baicalensis were negative

and these negative impacts were enhanced with drought aggravating.Total biomass decreased by about 16% and 30% under light drought

and decreased by about 44% and 35% under heavy drought.The fertilization effect on the two species weakened under soil drought

and it was more obvious on Aneurolepidium chinensis than on Stipa baicalensis.
