摘要:
以辣椒品种“天椒11号”为试材，采用 2.5%咯?恶霉灵、10%苯醚?嘧菌酯、10%甲霜?锰锌和17%多?福悬浮种衣剂包衣辣椒种子，以未包衣种子为对照，通过室内试验和田间试验研究不同种衣剂对辣椒幼苗生长和立枯病的防治效果，以期筛选出适于新疆辣椒生产的种衣剂，为辣椒高产栽培提供参考依据。结果表明：与对照相比，4种种衣剂处理均能提高辣椒种子发芽势、发芽率、发芽指数和活力指数，增加幼苗株高、根长、茎粗、叶龄、鲜干质量，抑制辣椒立枯病病菌效果较好，5种浓度下抑菌率在44.67%~91.33%，田间立枯病防效为61.97%~86.21%。综合各指标，10%苯醚?嘧菌酯悬浮种衣剂处理效果最佳。
Abstract:
In order to screen out suitable seed coating agents for pepper production in Xinjiang and provide a theoretical basis for high yield cultivation of pepper，‘Tianjiao No.11’ pepper was used as the material in this experiment，four suspended seed coating agents (2.5% fludioxonil?hymexazol，10% difenoconazole?azoxystrobin，10% metalaxyl?mancozeb and 17% carbendazim?thiram)were used as tested agents and the uncoated seeds were used as control in order to investigate the effect of different seed coating agents on the control effect of Rhizoctonia solani Kühn and growth of pepper via indoor experiment and field experiment.The results showed that all the four seed coating treatments could increase the germination rate，energy，index and vigor index of pepper seeds，and the plant height，root length，stem diameter，leaf age，fresh weight，dry weight also increased compared with the control treatment.Four seed coating agents had better inhibition effect on the pathogen of pepper Rhizoctonia solani Kühn，the inhibition rate was 44.67%-91.33%，the disease control effect in the field was 61.97%-86.21%.10% difenoconazole?azoxystrobin had the best control effect according to the comprehensive indexes.
