Abstract:
Eight-year-old winter jujube (Ziziphus jujuba Mill.cv.‘Zhandong 2’) was used as test material.Winter jujube trees received foliar spray of selenium,boron,and zinc micronutrient fertilizers in the flowering stage,with water used as the control.The effects of flowering and fruit setting of jujube trees,the mineral element accumulation,intrinsic quality attributes,and postharvest storability of jujube fruit on seven different fertilization treatments were studied (T1-T7),in order to provide reference for rational application of micronutrient fertilizers in winter jujube production.The results showed that the application of micronutrient fertilizers distinctly increased fruit setting rate,improved fruit quality attributes,and delayed postharvest fruit senescence of jujube,achieving overall superior results.Compared with the control,the fruit setting rate and plant yield under treatment T7 (50 mg?L-1 Na2SeO3+85 mg?L-1 polyborate+70 mg?L-1 IDHA-Zn) were increased by 0.33% and 12.48%,respectively.The contents of eight mineral nutrients (Se,B,Zn,N,P,K,Ca,and Mg) in T7 fruit sample were also prominently higher than those of the control.Additionally,the soluble sugar content and sugar/acid ratio were remarkably increased in T7 fruit sample,while the vitamin C and free amino acid contents reached 1.30 times and 2.20 times those of the control,respectively.After 7 days storage,the water loss rate,malondialdehyde content,and polygalacturonase activity of T7 fruit sample were considerably lower than those of the control,accompanied by enhanced fruit firmness and antioxidant enzyme activity (superoxide dismutase and peroxidase).Given its best comprehensive effect under the experimental conditions,the T7 treatment was recommended for promotion and application in facility cultivation of winter jujube in southern Shanxi Province.
