喷施生防菌剂发酵液对油桃植株性状的影响王鹏,韩娟,王信宏∗,侯冠宇(山东农业工程学院,山东济南250100)摘要为了研究生防菌剂在油桃栽培上的应用,采用哈茨木霉Ⅰ发酵液、哈茨木霉Ⅱ发酵液、木霉发酵液、黑根霉发酵液、哈茨木霉Ⅰ和哈茨木霉Ⅱ(1∶1)混合发酵液和木霉和黑根霉(1∶1)混合发酵液喷洒“离核甜”油桃地上部分,分析了喷施生防菌发酵液对油桃树形、花性状、叶绿素含量、坐果率等性状的影响。结果表明,喷施生防菌发酵液可以显著提高油桃冠幅和茎粗,降低株高,促进花器官的形成,增加油桃的花芽个数和花朵数,提高油桃叶绿素含量和坐果率。关键词生防真菌;油桃;哈茨木霉;木霉;黑根霉中图分类号S662.1文献标识码A文章编号0517-6611(2023)05-0138-03doi:10.3969/j.issn.0517-6611.2023.05.031开放科学(资源服务)标识码(OSID):EffectofBiocontrolFungiApplicationonthePlantAgronomicTraitsofNectarineWANGPeng,HANJuan,WANGXin⁃hongetal(ShandongAgricultureandEngineeringUniversity,Jinan,Shandong250100)AbstractTheaimofthisstudywastostudyontheeffectofbiocontrolfungiapplicationonthecultivatedtraitsofnectarine.Thefungalfer⁃mentedfiltratesofTrichodermaharzianum,Trichoderma,Rhigopusnigricansandtheirmixturewereusedforthecurrentinvestigation.Theplanttype,floraltraits,chlorophyllcontentandfruit⁃setratewereanalyzedafterbiocontrolfungiapplicationontheabovegroundparts.Theresultsshowedthatsprayingbiocontrolfungifermentationliquidcouldsignific...
