摘要
采用室内培养的方法,研究施肥条件下添加白云石粉对菜地土壤氮素形态转化的影响,结果表明:土壤铵态氮含量呈先增加后减少的趋势,而硝态氮含量呈逐步增加的趋势;随着白云石粉用量的增加,土壤铵态氮含量减少而硝态氮含量增加。
Effects of dolomite powder on nitrogen transformation in vegetable soil under the fertilization condition were studied by means of indoor cultivation. The results showed that, when applying dolomite powder, the content of ammonium nitrogen firstly increased and then decreased; however, the content of nitrate nitrogen gradually increased; following with the in- creased of dolomite powder dosage, the ammonium nitrogen contents decreased but the nitrate nitrogen content increased in vegetable soil.
