三十烷醇浸泡海带苗养殖效果试验

Trial research on kelp seedlings soaked in triacontanol

用不同浓度三十烷醇(TA乳粉)植物生长调节剂浸泡海带苗,观察其对海带生长的影响。结果表明:以0.8 mg/L浸泡海带苗的增产效果最佳,增产幅度达20.5%,其次为1.0 mg/L和1.5 mg/L,分别增产16.3%和13.1%;对生长速度、藻体色泽、藻体宽度、抗病能力等方面也有明显影响。

Using plant growth regulator triacontanol （TA） as raw material, five experimental groups were es- tablished for the control study of the effects on the growth of kelp seedlings＇ algae soaked in different concen- trations of TA. The study showed that kelp seedlings soaked in TA with the concentration of 0. 8 mg/L yielded the best result, the production was increased by 20.5%, followed by kelp seedlings soaked in TA with the concentration of 1.0 mg/L and 1.5 rag/L, with the production being increased by 16. 3% and 13. 1% respec- tively. It also showed significant effect of TA on the kelp seedlings＇ growth rate, algae color, width and dis- ease resistance.
