沼肥与化肥配施对生姜产量、品质及抗逆性的影响
Effects of combined application of biogas fertilizer slurry with chemical fertilizers on yields,quality and stress resistance of ginger
摘要
Abstract
To provide a basis for the application of combined use of biogas fertilizer(biogas slurry and biogas resi-due)and chemical fertilizers in ginger cultivation technology,Shannong No.1 ginger was selected as the experimental mate-rial,and treatments were set as follows:CK(chemical fertilizers only),T1 treatment(20％ biogas slurry+80％ chemical fertilizers),T2 treatment(50％ biogas slurry+50％ chemical fertilizers),T3 treatment(80％ biogas slurry+20％ chem-ical fertilizers),and T4 treatment(50％ biogas slurry+50％ chemical fertilizer+biogas residue as a substitute for base fertilizer).These treatments were designed to evaluate the effects of biogas slurry and biogas residues on the yield,quality,and stress resistance during the vigorous growth stage of ginger.The results showed that the yields of all treatments(except for T3 treatment)were significantly higher than that of CK,with the highest yield observed in T2 treatment.The application of biogas residues as a base fertilizer had the most obvious impact on ginger quality.In T4 treatment,the contents of soluble sugar,ascorbic acid,and gingerol in ginger rhizomes were significantly higher than those in CK.As the proportion of biogas slurry increased,the ni-trate content in ginger rhizomes decreased significantly un-der T4 treatment.Except for T3 treatment,all the other treatments could improve the stress resistance of ginger during its vigorous growth stage,characterized by increased activities of superoxide dismutase(SOD)and catalase(CAT),as well as the accumulation of flavonoids.However,when the proportion of biogas slurry reached 80％,the content of malondialdehyde(MDA)in ginger leaves increased significantly,while the content of glutathione(GSH)and the activity of CAT declined,indicating that lipid peroxidation occurred in ginger and the stress resistance reduced.In summary,the optimal application method for maximizing ginger yield was 50％ biogas slurry+50％ chemical fertilizer(T2).For improving ginger quality and stress resistance,the best application method is 50％ biogas slurry+50％ chemical fertilizer+biogas residue as a sub-stitute for base fertilizer.关键词
