[Methods] Different concentrations of organic nutrient solutions were sprayed on litchi leaves to study their effects on amino acid contents in the fruit of litchi cultivar "Qinzhouhongli". [Results] The results showed that the organic nutrient solution could significantly promote the growth of litchi fruit at various development stages and improve fruit quality by spraying the organic nutrient solution for 3 times with a dilution concentration of 500-1 500 times during fruit development(at an interval of 15 d) of litchi. It could increase the total essential amino acid, total semi-essential amino acid, lysine, phenylalanine, threonine, methionine, valine, leucine, histidine, arginine, aspartic acid, glycine, serine, proline, alanine and tyrosine contents. Spraying the organic nutrient solution with a dilution concentration of 1 000 times achieved the best effect of promoting the growth and improving quality of litchi fruit. [Conclusions] This study provides a theoretical basis for high-quality production and nutritional quality evaluation of litchi and the development of functional processed litchi products.展开更多
