摘要:
采用溶液培养法,研究了Fe2+质量浓度、Fe2+诱导时间、pH值、外源有机酸(草酸、苹果酸、柠檬酸)对根表铁膜形成及茶树吸收、富集氟的影响。结果表明:茶树根表铁膜主要集中在离根尖0.2~0.5 cm区域;茶树根表铁膜含量随Fe2+诱导时间的延长呈现先升高后降低的趋势,随Fe2+质量浓度的增加显著升高,与溶液pH、有机酸浓度呈负相关。当铁膜含量为2.40~13.60 mg·g-1,根表铁膜含量与茶树吸收、富集氟的能力呈正相关。与根表无铁膜的茶树单加氟处理的对照(CK1)相比,加Fe2+诱导形成铁膜后,茶树体内氟的含量增加了42.3%~103.7%;有机酸与Fe2+共同作用时,茶树体内氟含量显著增加了101.7%~243.0%。
Abstract:
The effects of Fe2+ concentration,Fe2+ incubation time,pH and organic acids including oxalic acid,malic acid and citric acid on iron plaque on root surfaces and fluoride absorption and accumulation in tea plants were investigated in the hydroponics condition.Results showed that most of the iron plaque induced on tea roots was concentrated between 0.2 cm and 0.5 cm from the root tip.As the Fe2+ concentration and incubation time increased,the amount of iron plaque increased,but negative relationships were found when pH as well as organic acids concentrations increased.When the amount of iron plaque was 2.40 to 13.60 mg·g-1,there was a positive relationship between fluoride adsorption and accumulation in tea plants and the iron plaque.Compared with CK1 without iron plaque and organic acids treatment,the amount of fluoride accumulated in tea plants increased between 42.3% and 103.7% with only Fe2+ treated.And it increased from 101.7% to 243.0% as the organic acids and Fe2+were added into the hydroponics solution together.
