摘要
为提高西兰花种子质量降低苗期病害发生率,研究了不同浓度的噁霉灵和精甲·咯菌腈种衣剂对西兰花种子萌发、幼苗生长及病害发生的影响.结果表明,相同药剂不同浓度拌种处理后两个西兰花品种种子的发芽势、发芽率和出苗率均呈先升后降的趋势.噁霉灵种衣剂浓度为 0.10%时,种子发芽势、发芽率相比噁霉灵种衣剂其他浓度处理高;3 mL·kg-1 精甲·咯菌腈种衣剂处理,种子发芽势和发芽率均高于精甲·咯菌腈种衣剂其他浓度处理,而且也是所有处理中效果最佳.研究结果为西兰花高质量种子加工技术提供了重要的借鉴和参考.
Abstract
In order to improve the seed quality of Brassica oleracea and reduce the incidence of seedling diseases,this study investigated the effects of different concentrations of hymexazol and metalaxyl-M·fludioxonil seed coating agents on seed germination,seedling growth,and disease occurrence of Brassica oleracea.The results showed that the seed germination potential,seed germination rate,and emergence rate of two Brassica oleracea varieties showed a trend of first increasing and then decreasing after being mixed with the same pesticide at different concentrations.When the concentration of hymexazol seed coating agent is 0.10%,the seeds germination potential and seeds germination rate were higher than other concentrations of hymexazol seed coating agent treatments;The germination potential and germination rate of the seeds treated with 3 mL·kg-1 metalaxyl-M·fludioxonil seed coating agent were higher than those treated with other concentrations of metalaxyl-M·fludioxonil seed coating agent,and it was also the most effective among all treatments.The research results provide important reference and guidance for the high-quality seed processing technology of Brassica oleracea.
