| 摘 要： | 以生长于土壤中易污染的马蹄莲小块茎为试材，对其降低污染措施进行研究：接种前先用杀菌剂（代森锰锌）对外植体进行预处理，后用不同种类、不同浓度的抗菌素处理，结果表明：用浓度为3g/L的杀菌剂，进行24h处理使污染率下降了52.97%，接着采用正交实验，用200mg/L氨苄西林钠、250mg/L硫酸链霉素、6.25mg/L硫酸庆大霉素，进行24h处理使污染率下降到21.34%，效果十分明显。

| Abstract: | We study a method of elimimation of fungi and bacteria contamination in Zantedeschia aethipica rhizomes. The rhizomes are pretreated first by germicide (Dithane M-45) and then treated by different antibiotic treatments. The results indicate that contamination percent decreases to 52.97% by 24 hours treatment with 3 g/L germicide, and to 21.34% by 24 hours one with 200 mg/L Ampicillin 250 mg/L Streptomycin 6.25 mg/L. This method is effective. |
