Reduced Chemical Fertilizer Combined With Bio-Organic Fertilizer Affects the Soil Microbial Community and Yield and Quality of Lettuce.

ABSTRACT: Reducing chemical fertilizers in combination with bio-organic fertilizers can limit the use of chemical fertilizers while maintaining soil fertility. However, the effects of combined fertilization on soil chemical properties, microbial community structure, and crop yield and quality are unknown. Using high-throughput sequencing, we conducted field experiments using lettuce plants subjected to five fertilization treatments: chemical fertilizer with conventional fertilization rate (CK), chemical fertilizer reduction by 30% + 6,000 kg ha^-1 bio-organic fertilizer (T1), chemical fertilizer reduction by 30% + 9,000 kg ha^-1 bio-organic fertilizer (T2), chemical fertilizer reduction by 40% + 6,000 kg ha^-1 bio-organic fertilizer (T3), and chemical fertilizer reducti
