为了探明潼关县秦东镇河滩地新增耕地土壤养分和重金属状况，通过测定当地土壤的有机质、全氮、有效磷、速效钾、有效硼、有效硅和交换性钙及土壤重金属量，及当地黄河水、渭河水、地下水和机井水水样的p H值、全盐量及重金质量浓度，分析了新增耕地的施肥及种植建议。结果表明，1）项目区水样的p H值、全盐量及重金属量均符合《农田灌溉水质标准》。项目区表层为粉壤土，表层土壤孔隙比例分配合理，具有一定通气透水性，满足水稻田耕作层的土质需求，但随土壤剖面深度增加黏粒量逐渐减小，砂粒量逐渐增多，饱和导水率逐渐增大。2）该区域土壤表层的速效钾（49～445 mg/kg）和交换性钙（35.4～78.33 cmol/kg）丰富，有效硼（0.56～0.77 mg/kg）和有效硅（30.1～87.9 mg/kg）中等水平，基本可以满足水稻的生长需求；有机质（0.72～17.5 g/kg）、全氮（0.24～0.91 g/kg）、有效磷（2.4～14.7 mg/kg）质量分数低，不能满足水稻的生长需求。3）表层土壤中重金属铬（23.9～120 mg/kg）、镍（22.5～40.1 mg/kg）、铜（10.1～45.7 mg/kg）、锌（42.0～95.4 mg/kg）、砷（8.6～12.3 mg/kg）、镉（0.110～0.132 mg/kg）、铅（19.9～27.6 mg/kg）、汞（0.048～0.122 mg/kg）质量分数符合《土壤环境质量标准》二级标准。综上可知，潼关县秦东镇河滩地新增耕地土壤可用于耕作，但应加大氮肥、增施磷肥。
In order to ascertain the status of soil nutrients and heavy metals in newly-added cultivated land in Qindong Town, Tongguan County, the contents of soil organic matter, total nitrogen, available phosphorus, available potassium, available boron, available silicon and exchangeable calcium and soil heavy metals P H value, total salt content and heavy metal mass concentration of the local Yellow River water, Weihe River water, groundwater and machine well water samples, and analyzed the fertilization and planting suggestion of new cultivated land. The results showed that: 1) The p H value, total salt content and heavy metal content of the water samples in the project area all met the criteria of “Irrigation Water Quality in Farmland”. The surface of the project area is composed of silt and loam, and the proportion of surface soil porosity is reasonable. It has certain aeration and water permeability to meet the soil requirements of paddy farming layer. However, with the increase of soil profile depth, the amount of clay particles gradually decreases, Gradually increase the rate. (2) The contents of available potassium (49 ~ 445 mg / kg) and exchangeable calcium (35.4 ~ 78.33 cmol / kg) kg). The organic matter (0.72-17.5 g / kg), total nitrogen (0.24-0.91 g / kg) and available phosphorus (2.4-14.7 mg / kg) were low enough to meet the growing demand of rice. Rice growth needs. 3) Cr (23.9-120 mg / kg), nickel (22.5-40.1 mg / kg), copper (10.1-45.7 mg / kg), zinc (42.0-95.4 mg / 12.3 mg / kg), cadmium (0.110-0.13 2 mg / kg), lead (19.9-27.6 mg / kg) and mercury (0.048-0.122 mg / kg) were all in accordance with the second grade standard of Soil Environmental Quality Standard. In conclusion, the newly-added cultivated land in Qindong Town, Tongguan County can be used for farming, but nitrogenous fertilizer should be increased and phosphorus fertilizer added.
