摘　　要：采用有机酸与硝酸铵协同浸种,研究其对黑麦草和高羊茅种子萌发及初期生长的影响,结果表明:苹果酸浸种黑麦草和高羊茅的最适浓度分别为15 mmol/L和5 mmol/L,而柠檬酸浸种的最适浓度则为10 mmol/L和5 mmol/L;最适浓度浸种条件下草坪植物的发芽率、种子活力与对照相比显著增加;同时根系生长与地上部分生长生物量积累也有很大增加。Used organic acids and ammonium nitrate to soak Lolium perenne L. and Festuca arundinacea L. seeds to study effect of germination and seedling growth. The results showed that the optimum concentration of malic acid used in soaking seeds for Lolium perenne L. and Festuca arundinacea L. were 15 mmoL/L and 5 mmol/L respectively, and the same index of using citric acid were 10 mmol/L and 5mmol/L. Compared with control, treatment with optimum concentration of organic acids could increase the ratio of seed germination and seed vizor index, simultaneously oromote root growth and overground biomass accumulation.
