摘　　要：以5年生太秋甜柿树为试材,于生长发育期分别进行叶面喷施3个浓度的螯合钙肥,研究对太秋柿生长发育的影响,以确定适宜的螯合钙喷施浓度。结果表明,与对照喷清水相比,叶面喷施螯合钙1000、500、200倍液都能不同程度地提高了太秋柿叶片生长量、光合色素、光合作用以及果实品质,其中500倍液提高程度最为显著,是太秋甜柿叶面喷施的适宜浓度。In this study,different concentrations of EDTTi-Ca were sprayed on the surface of 5-year-old Taishuu persimmon.Three concentrations of chelated calcium fertilizer were sprayed on the leaves during the growth and development period to study the effects on the growth and development of Taiqiu persimmon and determine the appropriate concentration of chelated calcium spray.The results showed that compared with the control group,foliar spraying of 1000,500,and 200 fold solutions of chelated calcium could improve the growth,photosynthetic pigments,photosynthesis,and fruit quality of Taiqiu persimmon leaves to varying degrees.Among them,the 500 fold solution showed the most significant improvement and was the appropriate concentration for foliar spraying of Taiqiu sweet persimmon.
