- 摘要:
- 以辽宁农业职业技术学院校内实训基地蔬菜日光温室内0～20 cm耕作表层棕壤土为研究对象，以沸石粉为试材，采用恒温振荡法，研究了天然沸石对水溶性氮、磷在设施土壤中迁移转化的影响，以期寻求提高水溶性氮磷肥利用率的最佳途径。结果表明：与对照相比添加天然沸石对水溶性磷含量影响不明显，但显著降低了水溶性氮含量，同时增加了土壤铵态氮和速效磷的含量；在富磷的设施土壤中添加沸石提高了有效磷含量，降低了磷损失的可能性；沸石在设施土壤中可以调节土壤氮素的保持和供给水平。
- Abstract:
- Taking the soil in 0~20 cm of solar greenhouse of Liaoning Agricultural Vocation-Technical College as object，with native zeolite as material，the effect of native zeolite on the unavailable process of water dissolvable nitrogen and phosphorus were studied using the constant temperature oscillation method，in order to improve the nutrient efficiency.The results showed that with the native zeolite additions，the concentration of water-phosphorus almost no change and water-nitrogen in solution decreased.The ammonium nitrogen and available phosphorus concentrations in the treatments with zeolite addition increased.Zeolite increased the available phosphorus concentration and decreased the probability of phosphorus pollution in solar greenhouse soils with high application of phosphorus fertilizer or high phosphorus concentration.For nitrogen，native zeolite could maintain a good nitrogen concentration.
