Abstract7 plant growth regulators （ 0.136% gibberellin·indoleacetic acid·brassinolide WP 75.0g/hm2 ， 0.1% triacontanol ME 1 000mL/hm2 ， 0.4% kinetin AS 937.5mL/hm2 ， 0.000 4% enadenine·oxyenadenine SP 750mL/hm2 4% gibberellic acid SL 500mL/hm2 ， 0.007 5% 14-hydroxybrassinolide AS 150mL/hm2 ， 2% potassium nitrophenolate AS 150mL/hm2 ） were used for spray treatment at the initial stage of tea bud germination and single bud stage， respectively，with spraying wateras the control（CK）.The effects of teaon the growth，yield，safetyandappearance quality of tea were analyzed.The results showed that the7 plant growth regulatorstested could increase germination densityandhadasignificant regulatory efectonthegermination and growth of tea buds.After thesecond spray，the fresh tea yield increased by 12.77% to 47.35% compared to the CK，among them，the treatment with 0.136% （2 gibberellin·indoleacetic acid·brassinolide WP at 75.0g/hm2 showed a significant increase in tea yield.7 plant growth regulatorswere found tobesafe for tea plant growth，improving product appearanceand quality （increased bud production，tenderleaves，uniform color，thickness，and sizeoftea shoots andleaves），while posing no harm to beeficial arthropods such asspiders.Thisarticle provides a reference forselecting suitable plant growth regulators to promote tea growth.
