| 摘 要： | 研究了一种肥料养分释放性能的快速测定方法。依据"淋溶法"原理设计了淋溶装置,考察了淋溶液流量对肥料氮、磷、钾与养分累积释放率的关系,并采用此装置测试了3种不同肥料的氮、磷、钾累积释放率,与实际效果完全一致。研究表明,采用"淋溶法",通过改变淋溶液流量可以实现肥料养分释放性能的快速检测。

| Abstract: | A quick testing method of nutrient release properties is studied. The leaching unit is designed according to leaching method, the effects of the leaching liquid quantity on cumulative release rates of N, P, K are discussed, release rates of N, P, K for 3 different fertilizers are determined by this unit, with the same results to practical situation. The research shows that nutrient release can be quickly tested by the leaching method through the changing leaching liquid quantity. |
