This paper reports the effect of DCD in seedling stage to soil microorganism of bacteria, mold and actinomycetes, and the concentration changes of both ammonium nitrogen and nitrate nitrogen in soil.
实验研究了双氰胺在玉米苗期对土壤微生物细菌、霉菌和放线菌的影响,及对土壤中铵态氮和硝态氮贮量变化的影响。
Even nitrogen, which is a gas in its elemental state, is normally absorbed from the soil as nitrate ions.
即使是元素状态为气体的氮,也通常作为硝酸根离子从土壤中被吸收。
Applying more nitrogen would increase the content of soil microbial biomass nitrogen, but might result in large amount of nitrate residue in soil and suspected to leaching loss.
继续增加施氮量,土壤微生物量氮含量增加,但土壤中残留大量硝态氮,易淋溶损失。
