摘要
以紫苏品种单面紫为试材,采用室内盆栽方式,研究50%敌草胺可湿性粉剂、8.8%精喹禾灵乳油不同施药量对紫苏生长及除草效果的影响。结果表明:施用750~2250g·hm^(-2)敌草胺,或450~1050mL·hm^(-2)精喹禾灵均能有效防除禾本科杂草和阔叶杂草,同时提高紫苏产量和总黄酮含量,且对紫苏产生的药害等级低于1.65。综合来看,播种覆土后土壤表面喷施1500g·hm^(-2)敌草胺(兑水量:1500kg·hm^(-2)),或在80%杂草处于3~4叶期茎叶喷雾900mL·hm^(-2)精喹禾灵(兑水量:600kg·hm^(-2))的处理效果较好。
This paper took perilla variety‘Danmianzi’as test material,carried out indoor pot experiment to study the effect of different dosages of 50%napropamide wettable powder and 8.8%quizalofop-p-ethyl emulsifiable concentrate on perilla growth and weed control.The results showed that applying 750-2250 g·hm^(-2) napropamide WP or 450-1050 mL·hm^(-2) quizalofop-p-ethyl EC could effectively control grass and broadleaf weeds,and at same time increase perilla yield and total flavonoid content of perilla,while making the level of phyto-toxicity on perilla lower than 1.65.On the whole,spraying 1500 g·hm^(-2) napropamide WP(water dosage:1500 kg·hm^(-2))on soil surface after sowing and before covering,or spraying 900 mL·hm^(-2) quizalofop-p-ethyl EC(water dosage:600 kg·hm^(-2))directly on grass when 80%weeds were in the 3-4 leaf stage had better results.
