该试验选择具有16年棚龄的北方大棚,选用腐植酸、沸石为主要材料,通过测土施肥的试验方法,研究设施农业次生盐渍土的阴离子含量状况。结果表明:施用无机肥料可以快速增加土壤表层0~20cm的阴离子盐分含量,但对20cm以下土壤阴离子影响不明显。测土配方施肥处理、测土配方施肥+腐植酸处理、测土配方施肥+沸石处理、测土配方施肥+腐植酸+沸石处理与农民常规施肥相比,在降低土壤盐分含量方面效果显著,各处理均能有效降低土壤的盐分离子NO3^-、SO4^2-、Cl^-、HCO3^的含量水平。
該試驗選擇具有16年棚齡的北方大棚,選用腐植痠、沸石為主要材料,通過測土施肥的試驗方法,研究設施農業次生鹽漬土的陰離子含量狀況。結果錶明:施用無機肥料可以快速增加土壤錶層0~20cm的陰離子鹽分含量,但對20cm以下土壤陰離子影響不明顯。測土配方施肥處理、測土配方施肥+腐植痠處理、測土配方施肥+沸石處理、測土配方施肥+腐植痠+沸石處理與農民常規施肥相比,在降低土壤鹽分含量方麵效果顯著,各處理均能有效降低土壤的鹽分離子NO3^-、SO4^2-、Cl^-、HCO3^的含量水平。

Using humic acid and zeolite as main materials, the effect of fertilization on major anion content in the second- ary salinization soil was investigated in 16 years greenhouse. The results showed that applying inorganic fertilizer could rapidly increase anion salt content in 0--20 cm soil layer, but no significant effect was observed in the following 20 cm layer. Comparing with conventional fertilization, soil testing fertilization, soil testing fertilization adding humic acid treatment, soil testing fertilization adding zeolite treatment, and soil testing fertilization adding humic acid and zeolite treatment all could obviously reduce the soil salt content, such as NO3^-, SO4^2-, Cl^-, HCO3^-.
