| 摘 要： | 目的]研究灌溉水与茶树氟含量的关系。方法]对四川南路边茶原料主产区的茶树和灌溉水中的氟含量进行了测定。结果]茶树1芽4叶新梢与当年生老叶氟含量范围分别为48.83~170.13 mg/kg和555.78~1 015.50 mg/kg,二者之间的差异可达4~15倍;灌溉水氟含量范围在0.08~0.40 mg/L,与茶树当年生老叶氟含量呈显著正相关,而与茶树1芽4叶新梢氟含量关系不明显。结论]为茶园灌溉水氟限量指标的制定及四川边茶降氟提供了参考。 |

| Abstract: | Objective] The aim was to study the relationship between irrigation water in tea plant and fluoride content in irrigation water.Method] Fluoride contents in tea plant and irrigation water from Sichuan South-road brick tea producing area were measured.Result] The fluoride content was 48.83-170.13 mg/kg in four leaves and a bud and was 555.78-1 015.50 mg/kg in old leaves of this year,thus the latter was 4-15 times than the former.The fluoride content in irrigation water was 0.08-0.40 mg/L,which had significantly positive correlation with that in old leaves of this year,but had no obvious correlation with that in four leaves and a bud.Conclusion] The research provides reference for formulating limit fluorine quantity index of irrigation water in tea garden and decreasing fluoride of brick tea in Sichuan. |
