Abstract
【Objective】 The effect of compound amino acid-Iron Fertilizer on iron content of kiwi fruit leaves,fruit quality and yield was investigated to screen the best spraying concentration of compound amino acid-Iron Complex Fertilizer which can be used in the fruit quality enhancement and the prevention and treatment of chlorosis.【Method】 5-year-old 'Qinmei' kiwifruit was used as test cultivar and the group which was sprayed clear water was used as control.Field experiment was conducted to study the effects of different concentrations of Compound amino acid-Iron Fertilizer(diluted 1 500,1 000,500 times) on kiwi fruit quality by determining the iron content of kiwi fruit leaves as well as the content of reducing sugar,titratable acid,vitamin C and iron in kiwi fruit and fruit yield in calcareous soil.【Result】 The results showed that spraying different concentrations of compound amino acid-iron fertilizer could significantly increase the iron content of etiolated kiwifruit leaves.Titratable acid in fruit first increased and then decreased with the increase of the concentration of compound amino acid-iron fertilizer.When compound amino acid-iron fertilizer(diluted 1 000 times) was sprayed,the fruit content of vitamin C,soluble solids and reducing sugar were the highest,the flavor was the best and the titratable acid was the lowest;When compound amino acid-iron fertilizer(diluted 500 times) was sprayed,the fruit iron content could be best increased.Compared with the control,spraying compound amino acid-iron fertilizer had no obvious effect on fruit yield.【Conclusion】 Considering the effects,the best concentration is 1 000 times of the compound amino acid-iron fertilizer on kiwi fruit quality under calcareous soil conditions.
