| Abstract: |
| To evaluate the effect of organic and chemical fertilizers on the leaf nutrient content, yield, and quality of cherry, a positioning field test of cherry varieties, “Leini” and “Bolante”, was conducted with 3 fertilizer treatments including chemical fertilizer (M0), 50∶50 organic∶chemical fertilizers (M50), and organic fertilizer (M100) for 4 consecutive years (2014-2018). The results showed that the treatments M50 and M100 on “Leini” increased soil organic matter by 42.50% and 33.00%, respectively. The M50 and M100 treatments on “Bolante” increased soil organic matter by 55.56% and 45.70%, respectively. They all were significantly higher than that with M0. The yield of “Leini” with M50 had steadily increased annually. The average yield of “Bolante” with M50 and M100 treatments decreased by 3.20% and 25.30%, respectively, over that with M0. The nitrogen and phosphorus contents of “Leini” leaf with M50 treatment were significantly higher than that of M0 and M100 treatments. The nitrogen content of M50 treatment was higher than that of M0 and M100 treatments by 10.50% and 18.59%, respectively. The phosphorus content of M50 treatment was higher than that of M0 and M100 treatments by 22.56% and 40.56%, respectively. “Leini” with M50 treatment had a vitamin C content of 46.67 mg·kg-1, significantly higher than other treatments. The soluble sugar of “Bolante” with M50 treatment was 14.51% higher than that with M0 treatment. The vitamin C content and soluble solid content of M50 treatment significantly increased by 7.69% and 9.35%, respectively. In summary, organic fertilizer replacing part of chemical fertilizers significantly improved the production. |
