Abstract:

In order to explore the effects of different fertilization treatments on the growth, yield and fruit quality of guava, no fertilization (CK), single application of organic fertilizer 15 kg/plant (T1), conventional application of compound fertilizer 2 kg/plant (T2), organic fertilizer 15 kg/plant+ compound fertilizer 1.6 kg/plant (T3), organic fertilizer 15 kg/plant+ compound fertilizer 1.2 kg/plant (T4) and organic fertilizer 15 kg/plant+ compound fertilizer 0.8 kg/plant (T5) were set up. The results showed that the branch length of T3 increased by 15.75% compared with T2, the longitudinal diameter of the two batches of fruits increased by 7.73% and 7.49% compared to T2, and the transverse diameter increased by 9.57% and 9.97%. The average single fruit mass of two batches of fruits treated with T3 increased by 18.80% and 21.36% compared to T2. The T3 and T4 had a better effect on improving fruit quality. Among them, the vitamin C content of the two batches of fruits treated with T3 increased by 19.98% and 10.80% compared to T2 treatment, and the soluble solids content increased by 19.61% and 11.30%. The total sugar content of two batches of fruits treated with T4 increased by 25.97% and 27.18% compared to T2, the reducing sugar content increased by 27.24% and 36.27%, and the crude fiber content decreased by 24.19% and 24.43%. To sum up, compared with the treatment of no fertilization or single fertilization, increasing the application of organic fertilizer by 15 kg and adding 1.2-1.6 kg of compound fertilizer per plant have a more significant promotion effect on improving the yield and quality of guava.
