| 中文摘要: |
| 通过田间微区试验,研究了异源养殖废水农业利用对耐盐能源植物(菊芋)栽培体系土壤性状、植物生长及产量的影响,同时利用Watersuit直观模型对系统作了安全性评估。结果表明:异源养殖废水灌溉土壤有明显积盐趋势,尤其是高盐度的对虾养殖废水,土壤盐分高达2.69 g/kg;而钠吸附比(SAR)海参养殖废水最高,其值为7.4(mmol/L)1/2;异源养殖废水灌溉菊芋茎叶生长受到抑制,但能明显促进根系生长;与淡水灌溉相比,除对虾养殖废水块茎产量受到影响外,其他两个养殖水处理块茎产量均无明显差异;以菊芋块茎产量作为基准,其耐盐临界值为24.65 dS/m。安全评价结果表明,适宜盐度养殖废水补充灌溉菊芋,可保证土壤安全和取得较高块茎产量。 |

| A field-trial was conducted on the use of agricultural wastewater to the salt-tolerant energy plants (Jerusalem artichoke) cultivation;meanwhile, soil properties, plant growth and yield were investigated, and than watersuit visual model was used to the security assessment on the soil-plant systems.The results showed that: heterologous wastewater irrigation could cumulate salts obviously, particularly for the high salinity of the prawn wastewater;the soil salinity was as high as 2.69 g/kg;and soil alkalization (SAR) in sea cucumber aquaculture wastewater was the highest, and its value reached 7.4 (mmol/L) 1/2.Stem and leaf growth of Jerusalem artichoke was inhibited under the aquaculture wastewater irrigation, but root growth could be promoted.Compared with fresh water irrigation, in addition to shrimp wastewater because of high salinity affecting Jerusalem artichoke tuber production, the yield in other two aquaculture wastewater irrigation treatments had no impacts on the Jerusalem artichoke production.The results further show that, provided the Jerusalem artichoke tuber yield as a benchmark, the threshold salt tolerance of the Jerusalem artichoke was 24.65 dS/m, and aquaculture wastewater for irrigation does not pose a threat to soil alkalization.Therefore, agreeable salinity of aquaculture water could be used to irrigate Jerusalem artichoke with high yield as well as soil safety. |
