草地土壤pH值测定方法比较研究
|
摘要
土壤酸碱度(pH)是判断土壤理化性质最重要的指标之一,影响着土壤的肥力和土壤养分的形态及有效性。选取5种草地类型土壤,分别采用国际和国内标准测定其pH值并探讨了影响测定结果的因素及两种标准之间的差异,结果表明:pH值测定主要受静置时间和水土比的影响,振荡时间对测定结果无显著影响;两种标准之间具有较好的相关性,其中国际标准测定结果稳定性高且具有可比性。基于以上研究,建议使用国际标准测定我国草地土壤pH值。
Soil acidity(pH) is one of the most important indices of soil physical and chemical properties and affects soil fertility and the form and effectiveness of soil nutrient. In this research, international and national standards were used to measure soil pH in five grassland types and the influencing factors were studied. We also discussed their difference between international and national standards. The results showed that pH determination was mainly influenced by standing time and the ratio of soil to water. However, shaking time had no significant effect on the determination results. There was a good correlation between the two standards. In addition, the analysis results determined by international standard were more stable and comparable. Based on the research, the international standard was suggested to determine the pH of grassland soil.
