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: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-algaes 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。

Through morphological analysis between male sterile plant and male fertile plant in the alabastrum period as well as in flowering period, one morphological mark was found that the alabastrum of male sterile plant was in cone shape; the alabastrum of male fertile plant was cylindraceous. The male sterile alabastrum and male fertile alabastrum were significantly different. The petal of male sterile is filiform but not lingulate and tubular , the normal one was just the opposite.
通过在蕾期和盛花期对不育系和可育系的形态性状进行分析,找到了一个与育性相关的形态标记,即不育系的花蕾呈圆锥状,而可育系花蕾呈圆柱状,二者形态差异极显著;花开放后,不育系的花瓣丝状化,没有舌状花和管状花之分,而正常可育系花序外围是舌状花,内部是管状花。
