查询词典 phosphorus

Total percent of carbon, nitrogen and phosphorus in Engraulis japonicus varied from 46.3% to 60.5%. And carbon content of Engraulis Japonicus was increasing and phosphorus was decreasing when growing from larvae to adult. However, there was not significant difference to nitrogen in different stages. Differences of nutrient contents in different life stages may be caused by changes in allocation of materials for growth within the body.

结果表明，碳、氮和磷三种元素占到鳀鱼体重的46.3-60.5％，其中碳元素含量与体长成正相关，磷元素与体长成负相关，氮元素与体长之间的联系并不非常明显，不同阶段的鳀鱼在元素组成上的差异直接反映了各阶段其需要不同物质。

The results indicated that vegetation biomass had a significant positive relationship with vegetation coverage. They had a significant negative correlation with bulk density of soil, and a positive correlation with macroaggregate, water stability macroaggregate, organic matter content, total nitrogen content, hydrolyzable nitrogen content, available kalium content, microbial biomass, and microbial respiration. However, they had no significant relationship with total phosphorus and available phosphorus.
