中文摘要 | 选择7种川中丘陵区常见沟渠植物(酸模、菖蒲、黑麦草、水芋、美人蕉、水蓼、野薄荷)作为研究对象,盆栽试验研究了不同植物对氮、磷的吸收能力,以期筛选出适应川中丘陵区沟渠生长的高富集氮磷植物。结果表明,所选用的其中6种植物在试验中均生长良好,但野薄荷在高氮、磷浓度的水体中生长受限。生长50天后,各种植物的地上部生物量在0.43~1.38 kg/m2之间,以美人蕉地上部生物量最大,菖蒲最小。7种植物地上部植株氮、磷含量分别在4.50~14.35 g/kg和0.80~2.15 g/kg之间(以干重为基础),植物地上部植株氮、磷吸收量分别在2.88~15.66 g/m2和0.48~2.04 g/m2之间。总的来说,7种植物均有一定的氮、磷吸收能力,其中以美人蕉和水芋对氮、磷的吸收效果最好。 关键词:氮磷;富集;沟渠;乡土植物;筛选 |
英文摘要 | Seven local ditch plant species ( Rumex L., Acorus calamus L., L.perenne, Colocasia esculenta (L.) Schoot, Canna indica L., Polygonum hydropiper, and Mentha haplocalyx Briq.) were selected to test their nitrogen (N) and phosphorus (P) uptake abilities for the ditch system in the Hilly Area of Central Sichuan Basin. Results showed that six of the seven species were able to grow well under the designed water N and P concentrations during the experimental period. The growth of Mentha haplocalyx Briq was constrained by the high water N and P concentrations. Aboveground biomass of the seven plant species ranged from 0.43 kg/m2 to 1.38 kg/m2 over a 50-day growth period, with the highest and lowest aboveground biomass for Canna indica L. and Acorus calamus L., respectively. The plant N contents ranged from 4.50 g/kg to 14.35 g/kg and plant P contents ranged from 0.80 g/kg to 2.15 g/kg, and the corresponding plant N and P uptakes were in the range of 2.88~15.66 g/m2 and 0.48~2.04 g/m2, respectively. Overall, Colocasia esculenta (L.) Schoot and Canna indica L. have the greatest plant N and P uptake ability across the seven investigated species |
