Although an order of magnitude smaller, the pore water pool can supply enough nutrients to build up the macrophyte bioma尽管数量级较小,孔隙水池可提供足够的营养来维持大型动植物的生存,但是需要周转得很快。
Although the biomass and yield of rice had been hardly affected by soil moisture content, when it was 80% or 100% of sat土壤含水量为饱和持水量的60%时对旱作水稻生物量和产量影响较大,而80%和100%时几乎没有影响。
