    摘要:

    为明确菌根化育苗基质对不同盐渍化土壤盐分及养分的影响,以加工番茄“屯河 5501号”为试验材料,采用轻度、中度和重度盐渍化土壤进行盆栽试验。研究加工番茄苗期、花期、坐果期、果实膨大期及收获期时,菌根化育苗基质对不同盐渍化土壤盐分、土壤有机质及速效养分的影响。结果显示:菌根化育苗处理的盐分含量均低于非菌根化育苗处理,且花期到坐果期时,在轻度和中度盐渍化土壤中存在显著性差异,分别降低了 7.2%、9.9%和 11.3%、22.5%,pH值随着生育期的递增逐渐增加。土壤中有机质、碱解氮、有效磷、速效钾含量均表现为重度盐渍化土壤 >中度盐渍化土壤 >轻度盐渍化土壤,重度盐渍化土壤较轻度盐渍化土壤中各指标含量最高分别增加了14.4%、102.2%、40.4%和43.1%,且非菌根化育苗处理高于菌根化育苗处理,并随着生育期的递增呈下降趋势。番茄产量随着盐渍化程度的加深逐渐减少,但在轻、中、重 3种盐渍化土壤中,菌根化育苗处理的产量均高于非菌根化育苗处理,分别增加了 11.8%、14.5%和 13.2%。菌根化育苗基质可减少不同程度盐渍化土壤中盐分的积累,促进土壤矿质养分的转化,减轻盐胁迫对作物的危害,通过菌根促进盐胁迫中植株对矿质营养的吸收,促进植株生长,增强植株对盐胁迫的耐性,最终提高产量。

    Abstract:

    The effects of substrate with inoculation of mycorrhiza on soil salinity and nutrients of processingtomato( “Tunhe 5501”)at seedlingstage,floweringstage,fruit settingstage,fruit enlargement stage and harvest stage were studied by potexperiment.The results showed that the salt content of mycorrhizal seedling treatment was lower than that of non -mycorrhizalseedlingtreatment,and there were significant differences in mild salinized and moderate salinized soil from flowering to fruitsettingstage,and decreased by7.2%,9.9% and11.3%,22.5%,respectively,while the soil pH increased graduallywith the growthperiod.The contents of organic matter,available Ncontent,available phosphorus content and availablepotassium content were all characterized by severely salinized soil>moderately salinized soil>mildly salinized soil,andincreased by14.4%,102.2%,40.4% and 43.1% in severely salinized soil than mild salinizedsoil,respectively.The nutrient contents of non-myeorrhizal seedling treatment were higher than mycorrhizal seeding treatment,and decreasedwith the growthperiod.The yield of processing tomato decreased with the increase of soil salinization degrees.However, the yield of myeorrhizal seedling was higher than non-mycorrhizal seedling in the mildly salinized,moderate salinized andseverely salinizedsoil,increased by11.8%,14.5% and 13.2% respectively.It indicated that substrate with inoculation ofmycorrhiza could reduce the accumulation of salt in different salinesoil,promote the transformation of soil mineralnutrients,relieve the persecution of crops caused by saltstress,promote the absorption of mineral nutrients by mycorrhizal under saltstress,and promote the plantgrowth,enhance plant tolerance to saltstress,and ultimately increaseyield.
