nitrification in soil的意思|示意

Isotope dilution method was adopted in lab for the study of the effect of crude oil contamination on the rate of nitrogen mineralization and nitrification in soil.

在实验室中用同位素示踪法，研究了土壤中不同石油污染量对氮矿化及硝化速率的影响。

In addition, by comparing the effect of UYJ to that of UJ, it could be speculated that the microbial agent inhibited nitrification insignificantly in tea garden soil with rich organic matter.

此外，比较UY J和UJ处理结果可以推测：在有机质丰富的茶园中施用菌剂来抑制硝化作用的效果不显著。

The maximum nitrification ratio of fertilizer N in soil is up to 20%-42%, according to the soil fertility and rate of fertilizer N applied.

氮肥中N在土壤中的净硝化率最高达42％，因土壤肥力和施N量不同而异。

The research results showed that the heterotrophic nitrification is the important microbiological process of N2O production in this kind soil.

实验结果表明：内蒙古温带草甸草原土壤N2O产生过程以硝化作用为主。

Compared with the previous crop type of soybean, rice planting in the previous season accelerated soil nitrification-denitrification rate in the following wheat season.

与前茬种植大豆相比，前茬作物水稻促进了后季麦田土壤硝化-反硝化作用。

Heterotrophic nitrification might be present in the tested soil.

供试土样可能存在异养硝化作用。
