Abstract: A 6-year-old forest age was selected in the Juglans regia fruit forest as material. The effects of the formula type foliar micro-fertilizer Lingdan on yield per plant and some traits affecting nut quality were studied. The results showed that the application of formula type foliar micro-fertilizer Lingdan had a great influence on the yield and agronomic traits of Juglans regia fruit. Applying the formula type foliar micro-fertilizer Lilydan can increase the amount of dried fruit produced, increase the kernel rate, and reduce the shape of Juglans regia fruit and the weight of Juglans regia shells, but does not affect the thickness of the shell.

Key words: Juglans regia, foliar surface micro-fertilizer, yield, quality, agronomic trait
