| 摘 要： | 利用田间试验与室内试验相结合的方法,研究碱化土壤施用脱硫废弃物对高羊茅(Festuca arundinacea)、垂穗披碱草(Elymus dahuricus)和多年生黑麦草(Lolium perenne)种子产量和质量的影响。结果表明:施用脱硫废弃物能显著提高3种牧草种子产量构成诸因子和种子产量,增加种子萌发速率和种子萌发活力指数,但对种子萌发指数无明显影响。以种子生产为目的,该区适宜种植垂穗披碱草和高羊茅。

| Abstract: | The effects of flue gas desulphurization by-product on Festuca arundinacea,Elymus dahuricus and Lolium perenne seed yield and quality on alkali soil were researched.The results showed that flue gas desulphurization by-product increased the seed yield components and seed yield of 3 grasses significantly,the seed germination rate and vigor index were increased also.But the effects on germination index was not significantly.Planting Elymus dahuricus and Festuca arundinacea were feasible when seed production was as main purpose. |
