0.136％赤·吲乙·芸苔可湿性粉剂促进茶叶生长药效试验研究

摘要

Gibberellin + heteroauxin + brassinolide (GHB) 0.136％ WP was showed to provide positive effects on tea concerning germination time and density,fresh and dry weight per 100 buds,and new shoots growth.Significant differences had been observed when compared to the contrast and control groups,and no phytotoxicity had been found.Finally,the tea which treated with GHB 0.136％ WP were tested for pesticide residue and quality,and the results showed that the pesticide residue was acceptable and the tea quality was improved.In summary,the extension of GHB 0.136％ WP on the tea production could be recommended with the application rate of 6 ～ 8g/667m2.%0.136％赤·吲乙·芸可湿性粉剂对茶树萌芽时间、发芽密度、百芽鲜重、百芽干重、新梢生长均有明显促进作用,且与对照药剂及空白对照处理区存在显著性差异.试验期间未发现有药害情况的产生,经农残检测,结果安全,经品质检测,品质提升,适合在茶树生产上推广使用.推荐使用剂量为6 ～8 g/667 m2.
