应用扫描电镜观察到三唑酮种衣剂(TriSCF)以具网眼结构的膜状物包被于小麦种子表面,膜状物厚度约4~7.5μm,种表包被率达95%;对照处理三唑酮可湿性粉剂(TriWP)拌种在小麦种表呈点状或片状零散分布,种表被药剂覆盖率低于80%。振荡试验中TriSCF包衣药剂脱落率为2%,显著低于TriWP干拌种(43%)或湿拌种(25%)。放射性同位素示踪检测表明,TriSCF包衣处理的小麦种子在17%含水量砂床上发芽1~7d内,保持种子内的14C-二唑酮放射性强度显著高于TriWP拌种处理,而然失到砂床上的14C-三唑酮放射性强度低开TriWP拌种处理。
Scanning electron microscopy (SEM) was used to observe that TriSCF was coated on the surface of wheat seeds in the form of membrane with mesh structure. The membrane thickness was about 4 ~ 7.5μm, Treatment Triadimefon WP (TriWP) seed dressing in the wheat seed table was scattered or patchy distribution, the table is covered by the drug coverage rate of less than 80%. The drop rate of TriSCF coating agent was 2% in shaking test, which was significantly lower than that of TriWP dry dressing (43%) or wet dressing (25%). Radioactive isotope tracer detection showed that TriSCF-coated wheat seeds germinated within 17 days of 17% water bed and maintained 14C-oxadiazolone radioactive intensity significantly higher than that of TriWP seed dressing, but lost The 14C-triazolone radioactivity on the sand bed was low to open the TriWP seed dressing.
