摘要
以赤子爱胜蚓(Eisenia foetida)处理混合比例为1∶1、2∶1、3∶1、4∶1、5∶1和1∶0的污泥和牛粪得到污泥蚯蚓粪,并以10%、20%和30%(干物质量)与黑土混合,研究其对万寿菊株高、茎粗、叶片数、分枝数、地上部生物量、地下部生物量、根冠比、花蕾数、产花量、花直径和花生物量等生长发育指标的影响.结果表明:蚯蚓粪明显促进了万寿菊的生长发育;污泥和牛粪比值越小,对植物生长发育越有利;蚯蚓粪含量超过一定量,万寿菊生长发育状况有所下降,20%配比处理对万寿菊生长发育最为有利.
The 1：1,2：1,3：1,4：1,5：1,and 1：0 mixtures of sewage sludge and cattle dung were treated with earthworm Eisenia foetida,and then,mixed with black soil in the proportions of 10%,20%,and 30% （dry mass） to investigate the effects of the vermicompost on the marigold plant height,stem diameter,leaf number,branch number,aboveground biomass,underground biomass,ratio of root to shoot,flower bud number,flower yield,flower diameter,and flower biomass. An obvious promotion effect of the vermicompost was observed on the growth of marigold. The smaller the ratio of sewage sludge to cattle dung,the better the growth of marigold; while a higher proportion of the vermicompost to soil would inhibit the marigold growth. In this study,a proportion of 20% vermicompost to soil was the best for the growth of marigold.
