Effects of organic source conditioners on strawberry quality and soil physi-cochemical properties and bacterial community structure
In order to improve the soil quality,reduce the amount of chemical fertilizer and improve the quality of strawberry,a plot experiment was carried out in greenhouse with Hongyan as the experimental material in this study.Five treatments were set up:conventional fertilization(CK),4 800 kg/hm2 organic source conditioner+conventional fertilization(T1),4 800 kg/hm2 organic source conditioner+base fertilizer reduction 10%(T2),4 800 kg/hm2 organic source conditioner+base fertilizer reduction 20%(T3),4 800 kg/hm2 organic source conditioner+base fertilizer reduction 30%(T4).The effects of organic source condi-tioner application and chemical fertilizer reduction on straw-berry yield,quality,root rot incidence,soil physical and chemical properties and soil bacterial community structure were analyzed.The results showed that compared with conventional fertilization,T1 treatment could significantly increase strawberry yield,soil organic matter content and pH value,and increase the relative abundance of Proteobacteria and Bacte-roidetes.The application of organic source conditioner could significantly reduce the incidence of root rot(39.68%-64.09%).T1 and T4 treatments could reduce the relative abundance of Actinobacteria.Soil available phosphorus content,available po-tassium content and organic matter content were the main influencing factors of soil bacterial community structure.T1 treat-ment had a better effect on increasing strawberry yield and improving soil bacterial structure.T4 treatment had a better effect on increasing soil organic matter content,improving aggregate structure and alleviating soil acidification.
