中文摘要	在实验室条件下,研究了生物质磺酸钙对荒漠沙土的改良作用。结果表明,沙土中添加2%生物质磺酸钙,土壤中有机质、全氮、速效钾、速效磷含量和土壤持水量均显著增加(P<0.05),土壤pH值由8.4下降至7.6;添加生物质磺酸钙室温放置30 d后,土壤有机质含量略有下降,速效磷、速效钾含量和电导率则显著增加(P<0.05),全氮、持水量和pH变化不显著。生物质磺酸钙可促进土壤微生物生长,添加生物质磺酸钙室温放置30 d后土壤细菌数量增加了320%,未添加生物质磺酸钙的土样中细菌数量仅增加60%;添加生物质磺酸钙室温放置30 d的处理土样在门、纲分类水平上物种数与对照相同,但物种组成比例发生了改变。在目、科、属和种4个分类水平上处理土样物种数目多于对照,表明添加生物质磺酸钙促进了原土样中丰度极低的微生物的生长,使土壤微生物的多样性水平得到提高。
英文摘要	The effects of biomass calcium sulfonate on improving desert sandy soil were studied in this paper.The results showed that the soil organic matter,total nitrogen,available potassium,available phosphorus and soil water holding capacity increased significantly(P<0.05),and soil pH decreased from 8.4 to 7.6 with the addition of 2% biomass calcium sulfonate.After adding the biomass calcium sulfonate into soil at ambient temperature for 30 days,the content of soil organic matter decreased slightly,while the contents of available potassium,available phosphorus and electrical conductivity increased remarkably(P<0.05),meanwhile,the soil pH,field capacity and total nitrogen basically remained stable.Adding the biomass calcium sulfonate into soil for 30 days,the amounts of bacteria increased by 320%,while which only increased by 60% in the control.Number of species in the treated soil was the same as that in the control soil at the division and class levels,but with different species composition.However,the number of species in the treated soil was higher than that in the control soil at order,family,genus and species classification levels,which showed that biomass calcium sulfonate plays an important role in promoting the growth and biodiversity of microbes in soil.
