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。The aim of this study was to study on the effect of biocontrol fungi application on the cultivated traits of nectarine.The fungal fermented filtrates of Trichoderma harzianum,Trichoderma,Rhigopus nigricans and their mixture were used for the current investigation.The plant type,floral traits,chlorophyll content and fruit-set rate were analyzed after biocontrol fungi application on the aboveground parts.The results showed that spraying biocontrol fungi fermentation liquid could significantly increase crown width and stem diameter of nectarine,reduce plant height,promote the formation of flower apparatus,increase the number of flower buds and flowers,increase the content of chlorophyll and fruit-set rate of nectarine.
