Abstract
Potassium level in previous nutrient solution for muskmelon varied considerably,which influenced plant growth and fruit quality formation.The effects of 120,240,and 360 mg/L potassium levels on plant growth,macroelement accumulation,amino acids and aromatic compounds in fruit were studied,in order to optimize potassium fertilizer application.The muskmelon vigorously grew at potassium level of 240 mg/L in nutrient solution,which was beneficial to macroelement absorption.However,no significant difference in leaves area and fruit weight were recorded among the three treatments.The concentration of TSS,glutamic acid,aspartic acid,alanine,and aroma components concentration were significantly increased in fruit flesh with 240 mg/L potassium level,which should improved the nutrition and taste quality of muskmelon.The excessive potassium level(360 mg/L)reduced fruit quality.Favorable nutrient and taste of muskmelon with medium culture were achieved when potassium level was adjusted to 240 mg/L.The muskmelon macroelement absorption ratio of N,P,K,Ca,Mg was 28∶5∶40∶21∶6 under this potassium level at harvest.
