中文摘要:
      通过土柱淋溶试验研究了石墨烯溶胶配施化肥后对土壤中养分流失的影响,以探究石墨烯溶胶的保肥作用。试验共设计5个石墨烯溶胶浓度,进行4次淋溶,测定每次淋溶液以及4次淋溶后的土壤的电导率、氮、磷、钾含量。结果表明:(1)石墨烯溶胶与化肥配施于土壤中后对淋溶液的电导率、氮、磷及钾的含量均有影响,且添加的石墨烯溶胶浓度越大影响越明显。添加石墨烯溶胶处理后的淋溶液中,硝态氮、总氮、磷的含量最大可分别降低88.2%,80.9%和84.7%。(2)4次淋溶后,添加石墨烯溶胶处理的土壤中氮、磷、钾的含量及电导率与对照相比均有增加,其中对总氮、总磷的持留效果最大可提高175.0%和59.3%,但对铵态氮的持留明显效果。(3)石墨烯溶胶对淋洗液和土壤的pH影响不明显。石墨烯溶胶与肥料施入土壤中,可明显减少土壤中养分的淋溶损失,对土壤中的养分有明显的持留效果,具有保肥的作用。
英文摘要:
      The effect of graphene solution combined with chemical fertilizer on the soil nutrients loss was studied by soil column leaching test, and the fertilizer retention effect of graphene solution was explored. A total of five graphene solution concentrations were designed, and four times leaching was carried out, the conductivity, nitrogen, phosphorus and potassium contents of each leaching solution and the soil after four times of leaching were determined. The results showed that:(1) Application of graphene solution combined with chemical fertilizer had effect on the conductivity, nitrogen, phosphorus and potassium contents of the leaching solution, and the greater the graphene solution concentration added, the more obvious the effect was. The content of nitrate nitrogen, total nitrogen and phosphorus in the leaching solution treated with graphene solution could be reduced by 88.2%, 80.9% and 84.7%, respectively. (2) After four times of leaching, the content of nitrogen, phosphorus, potassium and the conductivity value in the soil treated with graphene solution increased compared with the control, and the retention effects of total nitrogen and total phosphorus increased by 175.0% and 59.3%, but there was no significant effect on the retention of ammonium nitrogen. (3) The effect of graphene solution on the pH of the eluent and soil was not obvious. The application of graphene solution combined with chemical fertilizer into the soil could significantly reduce the leaching loss of soil nutrients, and had obvious retention effect of the soil nutrients. Graphene solution had the function of fertilizer conservation.
