海水灌溉条件下Salicorni省略对个体间养分积累及土壤盐分的影响韩文军

　　　　　Salicorniabigelovii韩文军1,濱村邦夫2,杨劼3(1.,010010;2.,680-8550;3.,010021):对海水灌溉下Salicorniabigelovii的不同种植密度及其个体间的养分积累及土壤盐分的影响进行了调查。结果表明:单位面积地上部的干质量随种植密度增加呈平缓增高,符合最终产量恒定法则;个体间竞争株质量随种植密度增加而降低;随S.bigelovii种植密度的上升,土壤的含盐量和电导率(EC)值明显降低,56株/m2处理区钠的吸收量达261.22g,在336株/m2处理区钠的吸收量高达489.99g;随种植密度的增加,个体间的无机盐含量略有下降,但没有显著差异,相反茎、叶中碳和氮含量呈上升趋势。:海水灌溉;盐角草属;种植密度;无机盐;电导率:Q945.1　　　:A　　　:1001-0629(2008)11-0036-04＊　:2hm2。40hm2,4.50.3hm2[1]。10%,[2-5]。,。,,Salicorniaeuropaea3840/m2,[6]。S.bigelov-ii,。1　,2003415—916,160d。S.bigelovii。,80cm×120cm7。(mg/L):350,810,520。0、56、112、168、224、280、336/m27。50%。3,80℃3d,。,10mol/L,(AA-6700)、、、,YANACO-CN-CORDERMT-700。3,10cm,80℃3d,,10mol/L,、、、。(∶=1∶10)(EC)。2　50cm,,,,3611/2008　　　PRATACULTURALSCIENCE2511Vol.25.No.11＊:2007-12-07:(2007-8-01);“”(2001-2010):(1967-),(),,,。Email:[e-mail]37　　　,(1)。1　S.bigelovii(n=3)(/m2)(cm)(g/)(g/m2)5654.53±6.6521.96±9.401248.10±534.3411257.03±3.0715.13±7.901647.72±851.8316865.10±8.7512.20±3.201928.02±193.2822459.83±4.617.30±2.061835.22±148.0528056.03±8.216.93±1.062174.24±154.5933656.36±2.816.10±1.122333.33±133.28　　S.bigelovii(1,2)。56/m2261.22g/m2,336/m2489.99g/m2(3)。、1%(4)。1%,(5)。　　,。S.bigelovii、,(2)。3　,[2],56～224/m2S.bigelovii,。,[7]。1　S.bigelovii2　S.bigelovii3　S.bigelovii11/2008　　　(2511)38　　　4　、5　、2　S.bigelovii、(/m2)(g/kg)(g/kg)5626.7123.992.310.7215.1513.790.610.3111227.2223.362.120.7826.1823.280.960.7216830.5019.022.890.8915.3912.290.370.3622425.3422.172.180.7517.4813.520.570.3828026.1019.281.060.7112.7012.950.380.3233626.4820.231.930.9315.5311.210.250.37。Atriplexves-icaria,180d,NaCl42.5g,A.vesicaria[8]。S.bige-lovii,56/m2261.22g,336/m2489.99g。。,,,、,,,[9]。S.bigelovii,、。,,。,S.bige-lovii、。Triticumaestivum、Zeamays、、GlycinemaxSolanumtuberosum,EC4dS/m,[10],。、、、Salicornia[11],,。PRATACULTURALSCIENCE(Vol.25.No.11)11/200839　　　[1]　GlennEP,HodgesCN,LiethH.Growinghalo-phytestoremovecarbonfromtheatmosphere[J].Environment,1991,34:40-43.[2]　SzabolcsI.,Agronomicalandecologicalimpactofir-rigationonsoilandwatersalinity[J].Adv.SoilSci.,1986,4:189-218.[3]　,,,.[J].,2008,25(2):21-25.[4]　,,.[J].,2007,24(12):30-34.[5]　,,,.[J].,2005,14(5):48-53.[6]　,,.[J].,2004,14(3):147-155.[7]　.———10[M].:,1973.8-12.[8]　.[J].,1999,28:464-468.[9]　,,,.[J].,1979,35:42-47.[10]　.[M].:,1987.70-73.[11]　AhmadR,MalikKA.ProspectsforSalineAgri-culture[M].USA:KluwerAcademicPublishers,2002.155-158.EffectsofplantingdensityofSalicorniabigeloviiunderseawaterirrigationonmineralcontentsinplantsandsalinesoilsHANWen-jun1,HAMAMURAKunio2,YANGJie3(1.GrasslandResearchInstituteofChineseAcademyofAgriculturalSciences,Hohhot010010,China;2.AridLandResearchCenterofTottoriUniversity,Tottori680-0001,Japan;3.InnerMongoliaUniversity,Hohhot010021,China)Abstract:Theeffectofplantingdensity(PD)onthegrowthandnutrientabsorptionofSalicorniabig-eloviiwasexaminedundersalt(NaCl)treatments.ThedryweightofshootincreasedinresponsetoPD.TheincrementindrymatterreachedpeakvalueatacertainPD.Thedryweightperplantde-creasedinresponsetoPDowingtoindividualcompetition.Theelectricconductivity(EC)valueandthesaltcontentofthesoildecreasedconspicuouslyinresponsetoPD.Theabsorptionofsodium(Na)byplantwas261.22g/m2underthePDof56plants/m2.Itincreasedto489.99g/m2under336plants/m2.ThemineralcontentsinplantstendedtodecreaseslightlyinresponsetoPD.Carbon(C)andnitrogen(N)contentinshootincreasedinresponsetoPD.Keywords:seawaterirrigation;Salicorniabigelovii;plantingdensity;mineral;electricconductivity200811《》　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　《》,,!11/2008　　　(2511)
