一种土壤调理剂的验收指标及检测方法的研究

Study on Acceptance Index and Detection Method of a Soil Conditioner

为建立松土精作为土壤调理剂的验收方法和验收指标,测定了市售松土精的黏均相对分子质量和疏松度。结果表明:疏松度可作为验收指标,具体指标为疏松度≥20%,平行测定结果绝对误差≤5%;采用分别静置24 h和216 h的疏松度数据建立相关性,建立了快速判定松土精疏松度的方法。

In order to establish the acceptance method and acceptance index of grondverbeteraar as a soil conditioner, the viscosity-average molecular weight and porosity of market grondverbeteraar are being determined. The results show that the porosity can be used as the acceptance index, the specific index is porosity ≥20%, the absolute error of parallel measurement results is less than 5%. The correlation between the porosity data of standing for 24 h and 216 h can be used to establish a rapid method to determine the porosity of grondverbeteraar.
