• This paper first reports the difference of soil algae community makeup , microorganism amount , and soil phosphate activity between leanness soils and richness soils
  本篇论文首先进行了贫瘠土壤与肥沃土壤表层土中土壤藻类种群结构、微生物数量以及土壤中三种磷酸酶活性的对比研究。
• The research soil samples are from maoxian and from sichuan university especially . the results show that the two kinds of soils differ greatly in soil algae population , microorganism number and soil phosphate activity
  研究结果显示贫瘠土壤与肥沃土壤之间的土壤藻类种群结构(土壤藻类的数量和土壤藻类的优势种群) 、微生物数量和土壤磷酸酶活性均有很大的差别。
• The paper fristly compared the fertile soil with the incinerated sterile soil on the number of micro - algae , soil ph value , soil organic matter soil available phosphorus and soil nitrogen . and then , the author put fertile soil , which included micro - algae , proportionally into sterile samples and cultivated them respectively under illumination condition ( micro - algae can live and reproduce ) and dark condition ( micro - algae will die in some time ) . the above indices were measured in 0 , 30 , 60 and 90days respectively , the analyse of the interrelation between the change of micro - algae ' s number and the changes of soil ph value , soil organic matter , soil available phosphorus and soil nitrogen indicated : ( l ) soil micro - algae which were native to fertile soil conld adapt to the changed circumstance and light acted as a decisive role to the distribution of soil micro - algae . under dark condition , the micro - algae ' s number declined gradually and went to zero in the end , while under illumination condition , on the 90th day , the micro - algae ' s number of per gramme was 6 - 7 times more than that of the beginning
  本文首先对肥沃土壤与经高温焚烧后的贫瘠土壤中的微藻数量、土壤ph值、有机质含量、有效磷含量和全氮量进行比较研究，然后将包含微藻的绿化苗圃地肥土按不同比例接种进入贫瘠土样中，分别在光照条件和黑暗条件下进行培养，在0天、 30天、 60天和90天分别检测以上指标，比较有光条件和无光条件下，即有藻条件和无藻条件下贫瘠土样所发生的变化，并分别对微藻数量的变化与土壤ph值、有机质含量、有效磷含量和全氮量的变化之间做相关性分析，以评估肥沃土壤中的微藻接种进入贫瘠土壤后的生长情况以及对贫瘠土壤的改良作用。研究结果表明： ( 1 )土壤微藻对环境有较强的适应能力，且光照对其分布起了决定性的作用。
• 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。
• ( 2 ) through consuming co2 and secreting alkaline matters from their cellls to soil , micro - algae can improve soil ph value , and transform the weak acid soil into weak base soil . ( 3 ) through photosysthesis transforming co2 into organic matters , micro - algae can increase the content of soil organic matter
  肥沃土壤中的微藻接种进入贫瘠土壤后，在黑暗条件下逐渐死亡，有光条件下的微藻经过一段时间的适应后，到第90天时，每克土中的微藻数量增长到接种量的7 - 8倍。
• The algae multiplied massively in suitable environment , and made the amount of available phosphorus in soil increase significantly . the influence of the base matter on available phosphorus in soil was much more significant . in the second step , nostoc commune and chlamydomonas sajao lewin were inoculated of different inoculation quantities to the barren soils
  实验是在贫瘠土壤种接种具有固氮能力的念珠藻(蓝藻类)和沙角衣藻(陆生绿藻) ，在0 . 1g 、 0 . 5g 、 1 . 0g 、 2 . 0g湿藻重500g土重的不同浓度梯度进行接种，进行常温下培养。
