Short-term (diurnal or daily) changes in fungal and bacterial biomass were studied using direct count. Diurnal changes in microbial biomass were found to be unreliable. Daily observations have shown that the length of fungal mycelium can change 3--4-fold within 10--30 days, and the number of bacteria, 2--3-fold, the frequency and amplitude of changes depending on the season. Fungal biomass was found to be greater than bacterial biomass by a factor of dozens; that is why, while estimating the biomass of soil fungi, other indices of the biological activity of soil (DNA content, enzymic activity, respiration, etc.) must be taken into account.
采用直接计数法研究了真菌和细菌生物量的短期（昼夜或每日）变化。发现微生物生物量的昼夜变化不可靠。每日观察表明，真菌菌丝体的长度在10至30天内可变化3至4倍，细菌数量可变化2至3倍，变化的频率和幅度取决于季节。发现真菌生物量比细菌生物量大几十倍；因此，在估算土壤真菌生物量时，必须考虑土壤生物活性的其他指标（DNA含量、酶活性、呼吸作用等）。
