研究了土壤微藻对于土壤理化及生物学性质的影响 ,并作定量及定性分析。以土壤和水为两种不同基质 ,在基质中接种 5种土壤微藻藻液 (立方色球藻、土生绿球藻、舟形藻、沙角衣藻以及由 4种藻种形成的混合藻液 ) ,进行见光和黑暗培养 ,分别在 0 ,2 0 ,4 0 ,60 d时 ,测定环境 p H值、微生物量 (不包括藻类 )、有机质含量 ,作极差分析和图形比较。研究结果表明 ,环境 p H值变化、微生物量变化和有机质含量变化在不同藻种相同培养条件下 ,存在一定的相似性。藻种变化对 p H值和微生物增加的影响大于因基质变化和光照变化所产生的影响 ;基质变化对于环境有机质含量的影响大于因藻种变化和光照变化而产生的影响 ;微藻在土壤中培养时的 3种数据变化均大于在水中培养时的 3种数据变化。
The effects of soil microalgae on soil physical and chemical properties and biological properties were studied and analyzed quantitatively and qualitatively. Soil and water as two different substrates were inoculated into the matrix with five kinds of soil microalgae algae liquid (Chroococcum chlorella, native Chlorococcum sp., Navicula alba, Chlamydomonas reinhardtii and mixed algae liquid ) For light and darkness. The p H value, microbial biomass (excluding algae) and organic matter content were determined at 0, 20, 40, 60 days respectively. The range analysis and pattern comparison were made. The results showed that there was a certain similarity between the changes of p H value, microbial biomass and organic matter content under the same culture conditions of different species of algae. The effect of algal species on p H value and microbial increase was greater than that on substrate change and light change. The effect of matrix change on environmental organic matter content was greater than that on algal species change and light change. The changes of the three kinds of data during the cultivation were all greater than those of the three kinds of data when they were cultured in water.
