In the longer term , the foraging of all these animals , together with leaching by rain and microbial activity , breaks down the carcasses , making the nitrogen , phosphorus and other nutrients available to riparian plants 经过长远的时间，所有动物的觅食行为、雨水的过滤与微生物活动，陆续分解了鲑鱼尸体，使氮、磷和其他养份有利于河岸植物的生长。
In a word , the changing of soil microbial activities and the functional diversity of microbial community reflected to some degree the evolvement law of environmental ecological function of soil contaminated with heavy metals 因此，在该复合污染生境中重金属的微生物毒性效应发挥主要由cd 、 cll两元素决定，其生物毒性顺序表现为： cd cu zn ph 。
Our results indicate interactions among earthworms , organic matter , and soil microbial activity that should alter the carbon and nutrient balance of northern hardwood forest surface soils , relative to non - invaded soils 我们的结果显示土壤在有蚯蚓,有机物,以及微生物的相互作用下将会影响到北部阔叶林表面的营养物质和碳含量的平衡,这些只是相对于没有受到侵袭的土壤来说的
Some soil microbial activity parameters and heavy metals contents were analyzed by principal component method . the results showed that the critical levels of cadmium and lead in red clayed soil and red sandy soil were 15 mg . kg - 1 and 0 - 15 . mg . kg - 1 , 200 mg . kg - 1and 200 - 400 mg . kg - 1 , respectively . soil microbial populations and functional diversities of microbial community have changed to some extent under the stress of cadmium and lead pollution 在本文中我们将供试红壤的上述微生物活性指标和2种重金属含量进行主成分因子分析，其结果得出，红黄泥和红砂泥的土壤微生物活性镉胁迫的临界承载量分别为15mg ? kg ~ 1和0 15 ? mg ? kg ~ 1 ；铅胁迫的临界承载量分别为200mg ? kg ~ ( - 1 )和200 400mg ? kg ~ ( - 1 ) 。
If crop types or cultivars can be treated at a range of timings in the year , then application to the treated crop ( s ) should be done over a range of representative timings , including that which leaves the shortest time between treatment and harvest and that of the least microbial activity in the soil , i . e . autumn / winter in northern europe 如果林型或者培育植物一年内能在固定的时间处理，那么林木的处理申请应该在一个有代表性的时间内完成，包括能让处理时间和收获时间相隔最短的时间段和土壤里微生物活动最少的时间段，比如，北欧的秋天和冬天。
The anti - microbial activities of crude ethanol extract from aerial parts of sophora alopecuroides and its petroleum ether , chloroform , n - butanol and water fractions of sophora alopecuroides to pythium aphanidermatum , fusarium oxysporum f . sp . cucumerinum , fusarium oxysporum f . sp . lycopersici , alternaria solani , pseudomonas pachrymans and xanthomonas vesicatoria were tested by mycelial radial growth test and agar - well diffusion 本实验采用带毒平板菌丝生长法和琼脂打孔药剂扩散法测定了苦豆子地上部分乙醇粗提物及其石油醚、氯仿、正丁醇和水层的不同极性溶剂萃取物对瓜果腐霉、黄瓜枯萎病菌、番茄枯萎病菌、番茄早疫病菌、黄瓜角斑病菌和番茄疮痂病菌的抗菌活性。
