摘要
研究了前胡水提液不同浓度和不同处理方式的最佳组合筛选试验,以及前胡与陈皮、金银花等12种常见中草药浓度为5000 mg/L的水提液混合施药对稻瘟病抗性的诱导作用。试验结果表明,用浓度为2500 mg/L的前胡水提液浸种,再用浓度为5000 mg/L的前胡水提液喷施可对水稻稻瘟病起到较好的防控效果;有9种中草药与前胡互作产生协同作用。前胡+陈皮混剂诱导效果最好,虽然与8%好米得相比有一定差距,但药效持久性与8%好米得无明显差异,药效可持续35 d左右。
This paper studied the optimal ratio screening experiments were carried out with different concentration and different treatment methods of Qianhu aqueous extract,and the effect of mixed application of 5,000 mg/L of water extract of Qianhu and 12 kinds of common Chinese herbs on rice blast resistance.The experimental results showed that Soaking the seeds with a mass concentration of 2,500 mg/L and spraying with 5,000 mg/L of the water extract of Qianhu can get a good control effect on rice blast;There were 9 kinds of Chinese herbs interacting with Qianhu,the best inducing effect of the mixture of Qianhu and tangerine peel,although there is a certain gap compared with 8%Probenazole,there is no significant difference of the efficacy durability of 8%Probenazole,and the efficacy can last for about 35 days.
