摘要
研究了黄土区白草群落６月和７月的生物量，测定结果：６月和７月地上生物量分别为９０．９７ｇ／ｍ２和９５．０２ｇ／ｍ２，地下生物量为３２４．００ｇ／ｍ２和４５２．６１ｇ／ｍ２。地上生物量积累很少，地下生物量积累较多，该现象决定于白草生长发育特点。
The biomass of P.flaccidum community in June and July was studied. The result showed that the aboveground biomass in June and July was 90.97 g/m 2 and 95.02 g/m 2 respectively; the underground biomass was 324.00 g/m 2 and 452.61 g/m 2 respectively. Accumulation of the aboveground biomass was few, but the underground biomass more. The phenomenon related to the characteristic of the growth and development of P.flaccidum.
