To explores the optimal formula and application quantity of fertilizer for 5-year-old Austral-ian macadamia trees,the experiment focuses on 5-year-old trees of varieties such as JW,OC,Gui Re 1,and 695.Different formula fertilizers are applied during various stages of fruit development,inclu-ding flower bud differentiation,flowering,fruit setting,fruit enlargement,and hardening periods.The study analyzed the effects of different formula fertilizers on physiological indicators of 5-year-old macadamia fruits of different varieties.The results showed that the following fertilizer combinations better yield-increasing effects.In practical cultivation,the yield increases with the increase in the ap-plication quantity of formula fertilizers at different stages,showing a positive correlation with the a-mount of fertilization.Rational and scientific fertilization results in larger macadamia nuts,signifi-cantly higher single fruit weight,rounder fruit shape,thinner fruit skin,increased fresh seed quality,and promotes the overall increase in macadamia nut production.
