Unverified喜酸植物（栀子、茶花、蓝莓、绣球）需pH 4.5-6.0，通用营养土多为pH 6.0-7.0偏中性，需额外掺硫磺粉或松鳞调酸82% similarUnverified喜酸植物（蓝莓/杜鹃/栀子/绣球）需要pH 4.5-5.5，普通插针pH仪精度不足以区分5.0与5.5的关键差异，种这类植物建议直接用pH试剂盒或高精度笔式pH计80% similarUnverified复配蓝莓提取物+叶黄素，兼顾花青素与黄斑保护，但单一成分含量相比专项高含量产品偏低，属于广谱低剂量路线65% similarUnverified液体比色试剂(如溴麝香草酚蓝类)读数精度可达0.2-0.3，优于pH试纸的0.5-1.0，适合需要精确调节土壤的杜鹃、蓝莓、绣球栽培63% similarUnverified看有效成分应认准花青素含量而非蓝莓提取物总量，优质产品标注花青素≥25%（如36%越橘提取物换算花青素约6-9mg/粒），劣质品仅标'蓝莓浓缩汁'含量极低62% similar
