- 摘要:
- 以矮牵牛为试材，以普通农田土壤为对照，研究了中国矿业大学南湖校区污水处理厂的生污泥、堆沤污泥作为栽培基质对矮牵牛生长和生理特性的影响。结果表明：生污泥和堆沤污泥对矮牵牛的生长和生理特性均有积极影响，可作为栽培基质。堆沤污泥对矮牵牛的生长和生理特性的促进作用更显著，与生污泥相比在株高、冠幅和分枝量上分别增长了32.36%、35.50%、91.75%，在花朵数、平均花期和平均花径上分别增长了54.10%、25.52%、10.47%，显著促进了矮牵牛的营养生长和开花质量，使矮牵牛的观赏性更强；在叶绿素总含量、过氧化氢酶活性和根系活力上分别增长了30.16%、12.00%、3.23%，增强了植株光合强度、抗衰抗逆性和根系活力，为更优的矮牵牛栽培基质。
- Abstract:
- Using Petunia hybrid as test material，the effect of primary sludge and composted sludge in South lake Campus of China University of Mining and Tecnology as culture medium on the growth and physiological characteristics of Petunia hybrid which was compared with normal farmland soil were studied.The results showed that primary sludge as well as composted sludge had positive effect on the growth and physiological characteristics of Petunia hybrida.Both of them were feasible acting as culture medium.Compared with primary sludge，the effect of composted sludge on the growth and physiological characteristics of Petunia hybrida were more notable，the plant height of Petunia hybrida increased by 32.36%，besides，the crown 35.50%，the branching amount 91.75%，the flower number 54.10%，the average flowering 25.52%，the average diameter of flower 10.47%.It promoted the vegetative growth and blossom quality of Petunia hybrida obviously and made Petunia hybrida more pleasing to eyes.In addition，the total chlorophyll content of Petunia hybrida increased by 30.16%，the catalase activity 12.00%，the root activity 3.23%.It strengthened the photosynthetic intensity of Petunia hybrida.As well，it improved the anti-aging resistance and the root vigor of life.It proved better culture medium for Petunia hybrida.
