浒苔生物炭与木醋液复配改良碱化土壤效果及提高油葵产量 总被引:2,自引:0,他引:2
为探究浒苔生物炭与木醋液复配改良碱化土壤效果及提高作物产量,以龟裂碱土为例,通过田间试验研究不同生物炭施加量(0、1%、2%和4%)与不同木醋液稀释倍数(0、2%)复配对土壤pH、碱化度、全盐、容重、速效磷、有机质、盐分离子、油葵生长和产量的影响,不施加生物炭和木醋液视为对照(CK).结果表明,2%浒苔生物炭+2%木醋液(V2BC2)改良龟裂碱土的综合效果最佳;在最佳处理条件下:①浒苔生物炭与木醋液复配能改善土壤理化性质,具体表现为作物生长期内土壤平均pH、碱化度和全盐含量显著降低,较CK分别降低12.14%、40.63%和42.75%,土壤容重显著减小,较CK减小20.78%;②浒苔生物炭与木醋液复配能显著降低土壤Na+、Cl-和SO42-含量,较CK分别降低47.17%、45.32%和33.33%,提高土壤K+和Ca2+含量,其他离子含量的差异不显著;③浒苔生物炭与木醋液复配显著提高土壤养分含量及有效性,增强土壤酶活性,与CK相比,速效磷提高2.88倍,有机质提高58.76%,土壤脲酶、碱性磷酸酶和蔗糖酶活性分别提高0.92、1.02和2.29倍;④油葵产量在V2BC2处理时最高,为3 546.7 kg-hm-2,较CK增产2 325.3 kg-hm-2.因此,浒苔生物炭与木醋液复配能进一步提高盐碱土改良效果及作物产量. 相似文献

Iron and steel manufacture has been ranked as the largest industrial source of environmental contamination in the USA; the wastes generated in their production processes contain heavy elements that can be a source of contamination, and natural radionuclides that can produce an occupational and/or public radiological impact. In this work the potential occupational effective dose rate (μSv/y) due to inhalation in four integrated steel-making factories from Egypt has been evaluated, by assuming a well defined scenario and with basis in the 210Pb and 210Po activity concentrations determined in ore and wastes collected in the aforementioned factories. Activity concentrations, in Bq/kg, of 210Pb and 210Po, and leachable Pb and Fe were measured using gamma-ray spectrometry based on HPGe detector, alpha particle spectrometry based on PIPS detector, and inductively coupled plasma-mass spectrometry (ICP-MS). Levels of 210Pb and 210Po in the range of <DL-4238 and 1-5660 Bq/kg, respectively, were found. According to the assumed scenarios, the occupational exposures by inhalation are much lower than the recommended annual effective dose limit, although the environmental impact due to waste storage and/or use should be considered based on case by case evaluation. 相似文献

Use of portable X-ray fluorescence spectrometry for environmental quality assessment of peri-urban agriculture 总被引:1,自引:0,他引:1

Urban expansion into traditional agricultural lands has augmented the potential for heavy metal contamination of soils. This
study examined the utility of field portable X-ray fluorescence (PXRF) spectrometry for evaluating the environmental quality
of sugarcane fields near two industrial complexes in Louisiana, USA. Results indicated that PXRF provided quality results
of heavy metal levels comparable to traditional laboratory analysis. When coupled with global positioning system technology,
the use of PXRF allows for on-site interpolation of heavy metal levels in a matter of minutes. Field portable XRF was shown
to be an effective tool for rapid assessment of heavy metals in soils of peri-urban agricultural areas. 相似文献
