  • 摘要: 使用建筑弃土与污泥堆肥配制营养土并应用于园林绿化。以凤仙花为研究对象,通过盆栽实验观察和对比分析了凤仙花从播种到开花整个生命过程的生长指标,并对其结果进行模糊评价。结果表明,凤仙花播种期和生长期各生长指标随着营养土中堆肥含量的增加而增加,并在堆肥施用量30%时达到最佳;营养土中的重金属对凤仙花的生长速度有抑制效应,主要集中在播种期和生长期初期,随着凤仙花的生长成熟,重金属的胁迫效应持续减少,并在成熟期显著降低,重金属对凤仙花地表部分的抑制更为明显;建筑弃土与污泥堆肥配制的营养土对园林植物营养效果良好,成熟期的凤仙花生物量大幅度增加,最大增幅550%;通过模糊评价并综合考虑配置方案,最佳堆肥施用量为30%。
    Abstract: Nutrient soil produced from the mixture of construction soil and (wastewater treatment plant, WWTP) sludge compost was applied in growing landscape plants. The performance of garden balsams from seeding to blooming period was observed and analyzed by pot-culture experiments to verify the application of the as-prepared nutrient soil on growing landscape plants. The results show that: (1) the application of the as-prepared nutrient soil conducts a positive influence on the growth of impatiens due to the rich nutrients; (2) the growth indices of garden balsams in experiments are positively proportional to the ratios of the WWTP compost in the nutrient soil, reaching maximum at the percentage of 30%; (3) heavy metals in the nutrient soil act as an inhibiting factor of the growth of garden balsams, especially to the part above the earth surface, and the inhibition take places mainly during the seeding and growing periods; however, this inhibition effect decreases as garden balsams grow, and mitigates evidently in the mature period; (4) the application of the nutrient soil leads to a significant increase of the biomass of garden balsams up to 550% at maximum, meeting the living condition of plants growth; (5) the optimum application rate of the nutrient soil on garden balsams is determined to be 30% under the experimental conditions by the fuzzy evaluation.
