On the 90th day , the content of organic matter of soil samples under illumination condition was 2 - 3 times more than that of the beginning . ( 4 ) micro - algae can decompose organic phosphorus into inorganic phosphorus and increase the content or the potential content of soil available phosphorus . ( 5 ) theoretically , because of some micro - algae ' s nitrogen fixation , the sterile soil ' s content of nitrogen should increase , but in 90 days , its increment could not be determined ( 3 )土壤微藻通过光合作用将二氧化碳合成为有机物，增加土壤的有机质含量，在90天的实验期内，有微藻生长的土样内的有机质含量是对照组的2 - 3倍。 ( 4 )土壤微藻作为溶磷微生物之一能够将有机态磷矿化成无机态磷，增加贫瘠土壤有效磷的含量或潜在的含量。
Mongolica young stand , secondary natural forest , and the mixed forest of larix olgensis and fraxinus mandshurica rupr . . countermeasures for controlling soil degradation were also recommended . the study got following results : ( 1 ) from young stand to mid - age of larix olgensis , with the closure of canopy and the decrease of undergrowth vegetation cover , soil acidity , enzyme activity , total inorganic phosphorus , available k , soil moisture and total porosity decreased significantly ; while soil organic matter content , humus component content , the amount of three main types of microbes , acid phosphatase activity , and bulk density in rhizosphere soil and non - rhizosphere soil increased with the increase of the amount of forest floor litter ; from mid - age stand to near mature stand , with the decrease of stand density and crown cover as well as the restoration of undergrowth vegetation after preliminary thinning , soil organic matter content , fulvic acid , exchangeable acidity , exchangeable aluminium , neutral phosphatase activity , total amount of inorganic phosphorus , the amount of actinomycetes , soil moisture , and total porosity in rhizosphere soil and non - rhizosphere soil apparently increased ; from near matu re stand to mature stand , soil activity acidity , organic matter content , humus component content , available phosphorus , total amount of amino acid , available k , soil enzyme activity , soil moisture , and total porosity in rhizosphere soil and non - rhizosphere soil decreased , but total phosphorus , soil acidity ( in particular , exchangeable aluminium ) , and bulk density increased 结果表明： ( 1 )从落叶松幼龄林到中龄林，随着林冠的郁闭和林下植被盖度的急剧下降，林地土壤酸度、土壤酶活性、无机磷总量、速效钾、土壤水分含量、总孔隙度呈明显下降趋势，而根际和非根际土壤有机质含量、腐殖质各组分含量、三大类微生物数量、酸性磷酸酶活性和土壤容重随着凋落物的增加呈明显上升趋势；从中龄林到近熟林，由于抚育间伐，林分密度及郁闭度下降，林下植被盖度逐步得到恢复，根际与非根际土壤有机质含量、富里酸、交换性酸、交换性铝、中性磷酸酶、无机磷总量、放线菌数量、土壤水分含量、总孔隙度呈明显的上升趋势；从近熟林到成熟林，随着林龄的增大，根际与非根际土壤活性酸、有机质含量、腐殖质各组分含量、有效磷含量、氨基酸总量、速效钾、土壤酶的活性、土壤水分含量和总孔隙度呈下降趋势，而根际与非根际土壤全磷含量、土壤酸度(特别是交换性铝)和容重呈增加趋势。
Respectively . laboratory tests on phosphorus release abilities of selected bacterial strains showed ipb could liberate more than 50 g / ml , while opb produced less than 2 g / ml water soluble inorganic phosphorus ( wsip ) every day , demonstrating the enzymes participating in solubilization of ca - p should be constitutive ferments and enzymes concerning with mineralization of lecithin might be inducible catalysts . low abundance and poor compositions of nitrogen utilizing bacteria suggested poor bacterial diversities and weak self - purification of the lake 对3株有代表性的无机磷分解菌和6株占优势的有机磷分解菌的鉴定显示， 3株无机磷分解菌与巨大芽孢杆菌、大地杆菌和janthinobacteriumlividum最相近，而6株有机磷分解菌分别为固氮螺菌，产气肠杆菌， blastobacteraggregatus ，表皮葡萄球菌，溶血不动杆菌和念珠菌。
Crystal zirconium phosphate - phosphonate has the stability and regulity of interlayer floor of inorganic a - zirconium phosphate , they still have the designability of the organic group in the interlayer and adjustment of the ratio of organic and inorganic phosphorus acid , they are a kind of potential smart material , we can process molecule design and optimize filtration according to the requirement of goal reaction , we can prepare special ion - exchange , catalyst , catalyst supporters nonlinear optics compound , solid state proton conductivity and the intercalation complex precusor by introducing different active organic group or active center into the choice and stable framework of inorganic a - zirconium phosphate 有机?无机晶态混合磷酸锆具有无机磷酸锆的层板稳定性和规整性，同时具有层间有机基团的可设计性和有机无机磷酸混合配比的可调节性的特点，是一类很有潜力的灵巧材料，并且可以根据目标反应的要求进行分子设计和优化筛选，在无机磷酸锆优良稳定的骨架上引入不同的活性基团或活性中心，可以制备出性能独特的离子筛、催化剂、催化剂载体、非线性光学物质、固态质子导体和制备插层复合物的前驱物。
