摘　　要：初步研究了农药悬浮剂冷、热贮不同时间后的粒子大小、粒度分布、黏度及悬浮率的变化规律。试验结果表明,30%甲硫.戊唑醇悬浮剂和40%戊唑.多菌灵悬浮剂热贮后中位径均变化不大,粒子的跨距、黏度均呈增大趋势,而悬浮率均呈显著降低趋势;冷贮对粒子大小、粒径分布及黏度的影响均不大,悬浮率均呈降低趋势,但并不明显。初步认为,经冷、热贮后农药悬浮剂物理稳定性影响因子有相似的变化规律。The change rules of particle sizes, particle size distributions, viscosities and suspensibilities of SC were studied preliminarily at different times after cold and thermal storage. The test results showed that the median-particle-sizes of thiophanate-methyl ＋ tebuconazole 30% SC and tebuconazole ＋ carbendazim 40% SC had little changes after thermal storage, the particle spans and viscosities had increase trends, but the suspensibilities decreased signally. The particle sizes, particle size distributions, and viscosities of the two SC after cold storage showed little changes, the suspensibilities showed decrease trends, but unobviously. The physical stability impact factors of SC after cold and thermal storage had similar change rules.
