摘要
[目的]评价生物有机肥料的环境效应,进一步改善生物有机肥的性能。[方法]施用生物有机肥,研究生物有机肥对土壤氨挥发和土壤氮、磷、钾淋溶的影响。[结果]施用生物有机肥后果园根区域土壤氮挥发损失率减少;与施用化肥相比,氮、磷、钾的淋溶损失率减少。[结论]施用生物有机肥可以减少土壤中氨挥发损失和氮、磷、钾的淋溶损失,增强土壤的保肥性能。
[Objective]The aim was to evaluate the environmental effects of bio-organic fertilizer,and further tap the performance improvement of bio-organic fertilizer.[Method]The effects of bio-organic fertilizer on ammonia volatilization and nitrogen,phosphorus and potassium leaching were studied.[Result]The rate of nitrogen volatilization reduced after the application of bio-organic fertilizer to the root zone soil orchard,and nitrogen,phosphorus and potassium leaching rate decreased compared with fertilizer.[Conclusion]Bio-organic fertilizer could reduce ammonia volatilization in soil loss,reduce nitrogen,phosphorus and potassium leaching,and increase fertilizer properties of soil.
