Effects of the combined application of bio-organic and chemical fertilizers on soil fertility,yield,quality,economic benefit of Fritillaria thunbergii
[Objective]The aim of this study was to address the issues caused by excessive fertilization and single fertilizer application in Fritillaria thunbergii cultivation,such as soil nutrient imbalance,soil acidification,reduced yields,and diminished quality.[Method]The variety Zhebei 1 was employed as the materials.Five treatments of different fertilizer ratios were tested as follows:no fertilizer(CK),90 kg/667m2 bio-organic fertilizer+40 kg/667 m2 calcium silicon magnesium potassium fertilizer+30 kg/667m2 com-pound fertilizer(T1),120 kg/667 m2 bio-organic fertilizer+40 kg/667 m2 calcium silicon magnesium potas-sium fertilizer+30 kg/667 m2 compound fertilizer(T2),150 kg/667 m2 bio-organic fertilizer+40 kg/667m2 calcium silicon magnesium potassium fertilizer+30 kg/667 m2 compound fertilizer(T3).The effects on soil fertility,yield,quality,and economic benefits of Fritillaria thunbergii were assessed to determine the opti-mal fertilizer ratio.[Result]The combined application of bio-organic and chemical fertilizers significantly increased organic matter content,available nitrogen(N),available phosphorus(P),and available potassium(K)in the soil.It also notably enhanced bulb diameter,individual bulb fresh weight,and overall yield of Frit-illaria thunbergii.Yield improvements were observed across all fertilization treatments,with T3 showing the highest increase(14.56%).The amalgamation of bio-organic and chemical fertilizers proved advanta-geous for boosting economic returns and quality of Fritillaria thunbergii.Compared to the control group,the content of Fritillaria thunbergii treated with T1,T2,and T3 increased by 4.9%,17.2%,and 19.5%,re-spectively.[Conclusion]It was suggested that the T3,i.e.,150 kg/667m2 bio-organic fertilizer+40 kg/667 m2 calcium silicon magnesium potassium fertilizer+30 kg/667 m2 compound fertilizer,can serve as the most suitable fertilization method for Fritillaria thunbergii cultivation in the region under study.
