西昌市土壤Fe、Mn、Cu、Zn有效性评价及其影响因素分析

在分析西昌市土壤微量元素Fe、Mn、Cu、Zn有效含量状况及其分布特征的基础上,从成土母质、土地利用方式、有机质和pH等4个方面探讨其对土壤微量元素有效含量的影响。结果表明:西昌市土壤有效Fe含量丰富,有效Cu和Zn略低且分布不均,有效锰有32.18%的土壤缺乏。成土母质是重要的影响因素,第四纪紫色洪冲积物发育的土壤Fe、Mn、Zn有效含量较高,二迭纪岩浆岩洪冲积物发育的土壤有效Cu含量较高,坡残积物发育的土壤4种微量元素有效态含量均较低;水田土壤各元素有效含量均大于旱地;有机质与有效Fe、Cu间显著正相关;pH值在中性偏碱时,有效Cu和Zn含量较低。     

黄河三角洲贝壳堤岛贝壳沙中微量元素含量及形态特征

通过对不同植被覆盖、不同剖面层次贝壳沙样品的采集与分析,研究了黄河三角洲贝壳堤岛贝壳沙中微量元素Fe,Mn,Cu,Zn的含量及形态特征.结果表明:贝壳沙中全Fe含量明显高于全国土壤中Fe的含量均值,而Mn,Cu,Zn 3种元素却远低于全国土壤中的含量.无论是表层样品还是剖面样品.微量元素含量均具有较大变异,且表层以下剖面样品4种元素含量高于表层样品含量.受植物生长的影响,有机枯落物较多的表层贝壳沙样品,其元素含量相应高于没有植被覆盖的表层样品.不同剖面样点自上而下,微量元素含量变化规律并不一致,其全量与有效态含量的相关性大小也不一样.Mn,Cu两种元素全量和有效态含量之间达到极显著相关水平(P＜0.01),而Fe,Zn两种元素全量和有效态含量之间的相关性却不显著,这可能是受元素种类与环境条件的双重影响所致.

山东典型植烟土壤微量元素有效态含量研究

为摸清山东典型植烟区土壤微量元素有效态含量分布情况,采集和分析了临朐、蒙阴、诸城、费县、五莲、莒县6个主要植烟县的烟田耕层和剖面土样。结果表明:①耕层土壤有效Fe和Mn含量丰富,有效Cu含量适中,有效Zn含量较低。②石灰性砂页岩发育的土壤中微量元素有效态含量相对较低。③有效态Fe、Mn和Zn主要为表层富集型,有效Cu垂直分布相对均匀。④土壤有效态Fe、Mn、Cu和Zn含量随pH升高而降低,随有机质增加而增加;pH是影响有效态Fe和Mn的重要因素,而有机质是影响有效态Cu和Zn的重要因素。

土壤微量元素的含量与分布特征是反映特定地区环境状况的一个重要因素,对土地资源的合理开发和利用具有重要意义.本研究以天山北坡三工河流域冲积平原型绿洲为研究区,选择盐土、潮土和灰漠土3种土壤类型,分析其B、Mn、Zn、Fe、Cu等微量元素的有效含量特征.结果表明:⑴以"全国农业系统的土壤速效微量元素丰缺指标"为标准,土壤有效Mn含量属于极低水平,有效Zn和Fe含量属于中等水平,有效Cu属于丰富水平,有效B属于极富水平;⑵三工河流域绿洲土壤中有效Mn、Zn、Fe、Cu含量与土壤pH呈负相关关系;土壤有机质对有效Fe、Cu含量影响很大;有机质和Mn的关系不明显,这和湿润地区研究结果存在显著差异;⑶不同的土壤类型对于土壤有效B、Zn和Fe的含量影响显著;潮土中微量元素的有效含量与盐土、灰漠土中含量相比有显著差异.     

稻草与生石灰对设施土壤微量元素含量和番茄产量的影响

为了探究设施内添加稻草与生石灰对土壤微量元素含量和番茄产量的影响,以长期施肥定位试验为依托,比较了施用鸡粪(M)的基础上,添加稻草(MR)、生石灰(MCa)、稻草与生石灰同时添加(MRCa)各处理全土及各粒级团聚体中有效态Fe、Mn、Cu、Zn含量和番茄产量的变化。结果表明:(1)添加稻草可增加土壤中有效态Fe、Mn、Zn含量,MR处理较M处理分别增加3.2%,80.9%,15.1%,对有效态Cu含量无显著影响;添加生石灰也可增加土壤中微量元素含量,其中Mn含量增加显著。土壤中有效态Fe、Mn、Cn、Zn含量与pH呈极显著负相关(P<0.01),与有机质含量呈极显著正相关(P<0.01)。(2)随着土壤团聚体粒级的减小,有效态微量元素含量呈下降趋势。添加稻草和生石灰可增加1~0.25mm粒级中有效态Mn含量,MRCa处理较其他处理增加6.6%~46.6%;添加稻草可增加<0.25mm粒级中有效态Zn含量。土壤中有效态Fe含量与<1mm粒级中含量呈显著正相关(P<0.01);土壤中有效态Mn、Zn含量分别与各粒级中含量呈显著正相关(P<0.01);土壤中有效态Cu含量与1~0.25mm粒级中含量呈显著正相关(P<0.01)。(3)施入稻草或生石灰可增加番茄产量,且稻草和生石灰同时施入产量最高,MRCa处理较MCa、MR处理分别增加12.6%,33.8%。土壤有效态Fe、Cu含量与产量正相关,其中有效态Fe含量对产量具有直接作用,决策系数最高,土壤有效态Cu含量对产量具有间接作用。因此,可以通过长期添加稻草和适量生石灰缓解设施土壤微量元素短缺的现状,且可获得最高作物产量,为设施内土壤可持续利用和设施农业可持续发展提供保障。     

Mehlich 3浸提剂在茶园土壤养分分析中的应用

Mehlich 3(M3)浸提剂是一种适合于不同类型土壤、能浸提不同有效态元素的通用浸提剂,而茶园土壤是一类较特殊的酸性土壤,它的强酸性、富铁铝等特性,是否适用M3浸提方式,国内鲜有报导。本文通过对目前较普遍适用茶园土壤的浸提方法与M3浸提剂相比较,结果表明M3浸提茶园土壤各元素有效态含量要高于常用浸提方法,K、Ca、Mg、Cu、Zn、Mn、Cr等元素含量结果相差不大,但Fe含量相差3倍,B、Cd等元素含量结果相差7～8倍,且各元素有效态含量呈极显著正相关。对M3方法及电感耦合等离子体光谱仪(ICP)精密度测定后认为M3方法结合ICP测定精密度高,结果稳定可靠。     

长期肥料试验对土壤和水稻微量元素及重金属含量的影响

长期肥料试验会影响土壤中微量元素和重金属状况以及作物对微量元素和重金属的吸收。本文研究了长期的不同施肥处理对土壤、糙米中微量元素Cu、Zn、Fe、Mn和重金属Pb、Cd含量的影响,结果表明:经17a连续施用猪粪及秸秆还田显著增加了土壤Cu、Zn和Cd全量,而土壤Fe、Mn和Pb全量在不同施肥处理间没有显著差异;施肥增加了土壤有效态Cu、Zn和Fe含量,其中施用猪粪及秸秆还田的3个处理显著增加了土壤有效态Cu、Zn和Cd含量,而土壤有效态Pb含量在不同施肥处理间没有显著差异。不同处理糙米Cu、Zn、Fe、Mn和Pb含量变化较小或没有显著性差异,而在3个施猪粪和秸秆还田处理中,糙米Cd含量均超过国家食品卫生标准(>0.2 mg kg-1)。水稻地上部吸收积累Cu、Zn、Fe、Mn、Pb和Cd总量与其地上部生物量呈正相关,土壤Cu、Zn、Cd有效态与全量含量呈极显著相关关系,而糙米中的镉含量与土壤镉含量有较好的相关关系。长期施用畜粪导致土壤Cd污染问题应引起高度重视。     

Comparison of soil tests to determine micronutrients status in Argentina soils

Abstract

Soil extraction techniques to measure the status of available micronutrients for plants are important in the diagnosis of deficiency or toxicity. Mehlich 3 (M3), EDTA (pH=8.2), DTPA‐TEA, and Soltanpour and Schwab (SS) solutions were confronted for their ability to extract simultaneously copper (Cu), zinc (Zn), manganese (Mn), and iron (Fe). Argentinean soils from different taxonomic orders with widely varying properties were investigated. The values obtained showed that DTPA‐TEA and SS solutions extracted similar amounts of Zn, Fe, and Mn, while EDTA dissolved comparatively higher amounts of Fe and Mn. Mehlich 3 yielded the highest extractions for the four micronutrients. Soil pH not only affected the extraction of Mn by DTPA‐TEA, SS, and EDTA extractions, but also the extraction of Fe by EDTA. The organic carbon affected the determination of Fe and Zn in all cases. The correlations of the different tests for Cu, Zn, Mn, and Fe were significant. The results suggest that for the determination of the bioavailable status of micronutrients, any of the studied tests could be applied using the soil edaphic properties as factors to improve the correlations between them and standardize the methods.     

黑土中有效态镍提取方法的选择

供试7种提取剂的最佳提取条件是:提取温度均为(25±1)℃;提取时间为DTPA 2 h,醋酸铵30 min,其余5种提取试剂60 min;提取时的土液比为蒸馏水和DTPA 1∶2,醋酸铵1∶10,其余4种提取试剂1∶5。DTPA作为提取剂时,盆栽作物的吸镍量与有效镍提取量之间的相关性达到极显著水平,并好于其它试剂。DTPA和EDTA作为提取剂时,有效镍提取量与植株干物重之间均达极显著的负相关,且相关系数高于其他试剂。考虑到用DTPA作提取剂时,可以同时测定铜、锌、铁、锰多种金属元素,因此黑土中有效态镍的最佳提取试剂是DTPA,最佳提取条件为:温度(25±1)℃、土液比1∶2、180次min-1往复振荡提取2 h。     

Evaluation of soil extractants to estimate available micronutrients under wheat‐field conditions

Abstract

Three extracting reagents were evaluated by correlation analyses to provide the best index of Zn, Cu, Mn and Fe availability to wheat (Triticum aestivum L.) plants growing under open field conditions. Twenty one soils were selected to obtain the widest range in properties of soils of the land wheat cultivated. The magnitude of the extractive power varied in the following order: 6NHCl ? EDTA + NH₄OA_C, pH4.65 > DTPA‐TEA, pH 7.3. The mild extractants, EDTA and DTPA, gave the same order of removal of micronutrients being Zn < Cu < Fe < Mn. The acid extractant was on the contrast more effective on Cu and Fe with respect to Zn and Mn, respectively. Wheat concentrations of Zn, Mn and Fe were significantly correlated to soil micronutrients. Highly significant relationships were found for Zn extracted by DTPA solution (r = 0.737***) and for Mn and Fe extracted by EDTA solution (r = 0.710*** and r = 0.564**). Plant Zn and Mn were also well predicted by the acid extraction. The absence of correlation for plant Cu vs. soil Cu occurred probably because of wheat concentrations almost constant, ranging from 5.0 to 8.0 mg/kg.     

Sonic dispersion of soil DTPA solution suspension as an extraction procedure for DTPA micronutrient test

Abstract

To examine sonic dispersion as an extraction procedure for DTPA micronutrient test, soil DTPA solution suspensions were sonicated to extract Fe, Zn, Mn, and Cu. The elements extracted after 15 or 60 seconds sonication were compared with those extracted after 1/2 or 2 hours shaking.

The mean differences between Fe, Zn, Mn, or Cu extracted after 15 seconds sonication and those extracted after 1/2 hour shaking were not significant. However, the extractions obtained after 2 hours shaking were significantly higher than those obtained after 15 or 60 seconds sonication.

The elements extracted after 15 or 60 seconds sonication correlated significantly with those extracted after 1/2 or 2 hours shaking. Therefore, 15 or 60 seconds sonication can replace 2 hours shaking in the extraction procedure for DTPA micronutrient test. However, 15 seconds sonication is more convenient than 60 seconds and does not require cooling of soil solution suspension during sonication. Therefore 15 seconds sonication ‐ a replacement for 2 hours shaking to extract Fe, Zn, Mn, and Cu ‐ is recommended.     

石灰性土壤有效硒浸提剂和浸提条件研究

采用外源硒加入土壤中得到硒污染土壤,6种有效硒的浸提剂NaHCO3、KH2PO4、K2SO4、EDTA、AB-DTPA和DTPA＋TEA＋CaCl2的最佳浸提时间和土液比进行了筛选,并通过盆栽试验对所选择的土壤有效硒浸提剂进行生物学校验,以找出石灰性土壤有效硒提取适宜的浸提剂及其浸提条件。结果表明,NaHCO3、KH2PO4、K2SO4、EDTA、AB-DTPA和DTPA＋TEA＋CaCl26种浸提剂有效硒浸提量都随着浸提土液比的减小而增大,且随浸提时间的增长而增大。其中NaHCO3和KH2PO4最佳土液比为1/15,振荡时间90min;K2SO4和AB-DTPA的最佳土液比为1/15,振荡时间60min;EDTA和DTPA＋TEA＋CaCl2的最佳土液比则为1/20,振荡时间30min。6种浸提剂在各自最佳的提取条件下提取的土壤有效硒量与白菜地上部分硒含量达极显著正相关,但土壤有效硒的提取量以DTPA＋TEA＋CaCl2及K2SO4最少,只占KH2PO4、AB-DTPA及EDTA提取量的14%～48%,故不适用于作为石灰性土壤有效硒的提取剂。NaHCO3适用于土壤硒含量高于5mg·kg^-1的石灰性土壤有效硒提取。KH2PO4、AB-DTPA及EDTA3种浸提剂既可提取土壤中水溶态硒,亦可提取部分的吸附态硒,提取硒数量较多,过程简单,重复性好,都可作为石灰性土壤有效硒提取的浸提剂。     

Reaction of EDTA,DTPA, and EDDHA Complexes of Zinc,Copper, and Manganese with a Calcareous Soil

Solutions of Zn, Cu and Mn chelates of EDTA, DTPA and EDDHA were reacted separately with a calcareous soil for periods up to 28 days. DTPA was an effective chelate for Zn and Cu; more than 77 and 55% of the added Zn and Cu, respectively, remained soluble after 28 days of reaction with the soil. The stability of Zn-EDTA and Cu-EDTA was relatively less than those of the respective DTPA chelates, whereas Zn-EDDHA and Cu-EDDHA were highly unstable in the soil. The loss of soluble Mn from Mn-EDTA, Mn-DTPA and Mn-EDDHA additions to soil was very rapid and completed in about one week. It was found that adsorption of Zn-EDDHA, Cu-EDDHA and Mn-EDDHA molecules by the soil was the main process removing Zn, Cu and Mn from solution. Whereas, replacement of the metal in the metal-chelate molecule by Ca ion from the soil was a more serious factor affecting the stability of DTPA and EDTA chelates of Zn, Cu, and Mn.     

二氧化碳联合螯合剂强化向日葵修复铜污染土壤研究

【目的】以向日葵为研究材料,探讨其在CO2浓度升高条件下修复铜(Cu)污染土壤的效率以及对比CO2与螯合剂联合诱导下向日葵对铜污染土壤修复效率的差异,并筛选出对CO2浓度升高响应显著的品种,以期为利用植物修复铜污染土壤提供数据支撑。【方法】 在设置两个CO2浓度的人工气候室内(正常浓度370 mol/mol和升高浓度800 mol/mol),采用完全随机设计的盆栽土培试验,通过5个不同品种的向日葵,向铜污染水平为100mg/kg的土壤上施加不同浓度EDTA和DTPA,研究CO2浓度与螯合剂联合施用对向日葵修复铜污染土壤效率的影响。【结果】 1)不同螯合剂用量对铜污染土壤的浸提效果显著不同,根据螯合剂浸提土壤铜的高含量低毒性效应,选取EDTA 3 mmol/kg土和DTPA 5 mmol/kg土作为螯合剂的施加剂量。2)施入螯合剂后,CO2浓度升高一定程度上缓解了向日葵的失绿、 失水,增加了食葵3号和阿尔泰2号的总生物量,但降低了食葵4号和阿尔泰1号的总生物量。3)在相同CO2浓度下,加入螯合剂后明显提高土壤pH值,且DTPA处理的增幅明显高于EDTA处理。CO2浓度升高处理虽对土壤pH值有影响,但CO2施肥与不施肥处理间五个品种的土壤pH值无显著差异。4)试验选用的5个品种中,食葵4号、 阿尔泰1号在CO2浓度升高后,向日葵地上部蓄铜量明显降低;食葵3号、 油生引2号在CO2浓度升高后,向日葵地上部蓄铜量略有升高;阿尔泰2号在二氧化碳浓度升高后,向日葵地上部蓄铜量明显升高。CO2与DTPA 5 mmol/kg土联合施用, 5个品种向日葵茎叶内铜含量较对照增加239％～646％;铜蓄积量较对照增加230％～362％。二氧化碳与EDTA 3 mmol/kg 联合施用时,EDTA的活化作用未达到最佳效果,对5个品种向日葵茎、 叶内铜含量的影响不一致。【结论】CO2浓度升高一定程度上可以增强向日葵的抗性。在100 mg/kg铜污染土壤上,阿尔泰2号对二氧化碳浓度升高的反应最敏感,同时二氧化碳与螯合剂联合施用时,螯合剂可能是影响土壤pH值变化的主要因子。在铜污染水平为100 mg/kg的土壤上,与EDTA施用量为3 mmol/kg土相比,5 mmol/kg土的DTPA与CO2联合施用的修复效果更好。     

Prediction of available heavy metals by six chemical extractants in a sewage sludge‐amended soil

Abstract

In a field experiment conducted during three years in a sandy‐loam, calcareous soil, one aerobically digested sewage sludge (ASL) and another anaerobically digested sewage sludge (ANSL) were applied at rates of 400, 800, and 1,200 kg N/ha/year, and compared with mineral nitrogen fertilizer at rates of 0, 200, 400, and 600 kg N/ha/year in a cropping sequence of potato‐corn, potato‐lettuce, and potato, the first, second, and third year, respectively. Results showed that the highest values of soil extractable metals were obtained with aqua regia, whereas the lowest levels with DTPA. All metal (Zn, Cu, Cd, Ni, Pb, and Cr) gave significant correlations between metal extracted with the different extractants and metal loading applied with the sludges. The metal extractable ion increased over the control for Zn, Cu, Cd, Ni, Pb, and Cr extracted with DTPA, EDTA (pH 8.6) and 0.1 N HC1, for Zn, Cd, Ni, Pb, and Cr extracted with EDTA (pH 4.65) and AB‐DTPA, and for Zn, Cd, Ni, and Cr extracted with aqua regia. The level of metal‐DTPA extractable resulted highly correlated with that obtained by the other methods, except the Ni‐aqua regia extractable. The soil extractable elements which showed significant correlations with metals in plant were: Zn, Cu, Cd, and Ni in potato leaves, Cd, Ni, and Pb in corn grain, and Zn and Cd for lettuce wrapper leaves. In general, all the chelate based extractants (DTPA, EDTA pH 4.6, EDTA pH 8.6, AB‐DTPA) were equally useful as indicator of plant available metals in the soil amended with sludge.     

Comparison of four extractants and chemical fractions for assessing available zinc and copper in soils of India

Abstract

Relative suitability of different extraction procedures for estimating available zinc (Zn) and copper (Cu) in soils was assessed using DTPA, 0.1 N HCl, ammonium acetate+EDTA, and double acid (HCl+ H₂SO₄) as extractants and rice as a test crop in Neubauer experiment. The relationships between Zn concentration and uptake of Zn by rice plants and Zn extracted by the different methods showed that DTPA‐TEA, pH 7.3, could very suitably be used to assess Zn availability in soils. However, 0.1 N HCl was better for assessing the Cu availability in soils to the rice plants. Water‐soluble and exchangeable fractions of Zn and Cu had significant positive correlations with Zn and Cu concentrations, respectively obtained by all the four extractants tested. The results also showed that DTPA and ammonium acetate+EDTA extracted organically bound Zn, whereas DTPA, 0.1 N HCl and ammonium acetate+EDTA extracted organically bound Cu. Water‐soluble, exchangeable and organic matter bound fractions exhibited significant relationships with Zn and Cu concentrations, their uptake and rice dry matter yield.     

Effect of elemental sulphur and sulphur containing waste in a calcareous soil in Turkey

The effect of elemental sulphur (S) and S containing waste applications on soil pH treated with 0–2,000 kg ha^‐l elemental S, and 0–100 tons ha‐¹ of waste was determined in the field and the pots. Sorghum (Sorghum bicolor L.) was grown in a Lithic Xerorthent soil which was taken from where the field experiment was conducted in pots receiving 5 kg soil. Plants were harvested 20 weeks after planting or 30 weeks after the applications for determination of dry matter yield and phosphorus (P), iron (Fe), zinc (Zn), manganese (Mn), and copper (Cu) uptake by shoots. EC, NaHCO₃‐extractable P, and DTPA‐extractable Fe, Zn, Mn, Cu also were measured in pot soil at the 5th, 10th, and 30th weeks. All treatments led to a decrease in soil pH though pH tended to increase again during course of time in both field and pot experiments. The both elemental S and waste applications in pot experiment caused an increase in dry matter yield and P, Fe, zinc (Zn), Mn and Cu uptake (mg pot^‐1) by shoots in sorghum plant. There was also an increase in EC of soil due to both applications of S. The concentration of available P extracted by NaHCO₃ in the pot soil, though not significantly different, was slightly higher compared with the control. Waste applications increased DTPA‐extractable Fe content of the soil, DTPA‐extractable Mn and DTPA‐extractable Cu. DTPA‐extractable Zn content, however, was reduced by the same applications.
