am真菌和施磷量对白术生长和品质影响word格式论文.docxVIP

河北大学理学硕士学位论文同而异。本试验结果表明，Glomusmosseae在白术生长后期的表现效果最好。4.接种Glomusmosseae对自术生长和代谢活动的促进作用，仅在一定磷素水平下存在。如果磷素水平过高，情况会发生逆转。综合考虑，盆栽试验最佳的磷素水平是gPlkg土。5. 适磷水平下，接种株叶片可溶性蛋白含量和叶片保护酶活性提高，说明接种Glomusmosseae 不仅有利于促进植物生长，还能增强植物的抗逆性。6.接种AM真菌对挥发油含量有一定程度的提高，最佳磷水平是0.1gPlkg土。7.白术是容易发生病害的根茎类药用植物，过多使用农药会产生药害，降低品质，施用生物肥料可以提高植株的抗病性和抗逆性，提高产量和品质，而且不会产生肥害和药害，符合《中药材栽培质量管理规范))，是种植中药材的发展方向。关键词丛枝菌根真菌:磷素:生长:品质:白术AbstractAbstractAMfungiisakindusefulmicroorganismthatdistributesinthesoilsystemextensively; itcanformsymbiosiswi也hostplantabove90%.Thesymbiosiscanpromotehostplanttoabsorbsoilmineralelement，regulateintemalmetabolizalactivityandimprovestresstoleranceofplant.TheusefulroleofAMfungitocropshasbeeninfluencedbyecological conditions，suchasthephosphorisanimportantfactor.Phosphorisoneoftheindispensablenutritiononplantgrow由anddevelopment.One-也irdtoone-secondsoilsisabsentphosphorinChinesecultivatedland.ηleavailable phosphor ofsoilslessthan 10mglkg existsthroughout the coun町.Innorthward 缸eaofChina，soils lack of phosphor has becomeone of the chief limiting factors about yieldincreaseofcrops.Increasingofphosphorusfertilizeraccommodatingwillbelimitedaboutthequantityofphosphate.Currently出apotentialbiologicalphosphatefertilizer，AMfungihavebeenextensiveresearchedintheworld.Theirapplicationhasbroadprospectsnotonly intheuseoflimitedresources，soilnutrientsandfertilizersbutalsotoreducefertilizerconsumptioninsustainableagriculturalproductionsystems.Atractylodes macrocephalaKoidz.isaperennialherbsofCompositae，itsrootscanasmedicine.Inrecentyears，Atractylodesmacrocephalahasbeenexportedtoabroad，domestic demand has been increasing，market demand becomes larger，wild reso田ces decline，soartificialcultivationbecomesthemainso町ceofdemand.PotexperimentwasconductedtostudytherelatedeffectofAMfungiongrowthandqualityofAtracrylodesmacrocephalawithaviewtopromoteplantgrowthandenhanceits medicinalingredients.WehopeitcanpfO\-划ethebasisforAMfungiintheapplicationofmedicinalplants.Themainresultsasfollowing:The results showed that G
