Abstract
【Objective】In order to improve yield and quality of muskmelon,the optimum amount of nitrogen and potassium fertilization under the different ventilations in greenhouse was studied.【Method】With muskmelon as teset material,the effects of the different fertilization amounts of nitrogen and potassium on growth and quality of muskmelon under the three different ventilation environments(TL:ventilation rate 90%,TM:ventilation rate 50%,TT:ventilation rate 10%) were studied by using pot culture.【Result】The stem diameter,leaf area and the quality reached the maximum under the conditions of the TT ventilation and moderate fertility(N 13.8 g/plant+K2O 20 g/plant),and sugar content of the fruit reached the maximum under these conditions and high fertility(N 18.4 g/plant+K2O 25 g/plant).The soluble solid content of the fruit reached the maximum under the conditions of the TL ventilation and the low fertility,but the content of soluble protein was the lowest.The vitamin C content of the fruit reached the maximum under the conditions of the TM ventilation and the mderate feritility.The absorption of the K elements showed rising trend under the three ventilation conditions and the three fertilizer treatments in melon's leaf.The absorption of the N elements showed downward trend under the treatment of the high and low fertility,but a rising trend after 45 days.【Conclusion】In autumn,the yield and quality of msukmelon are improved under such conditions as fertilizer rate N 13.8 g/plant+K2O 20 g/plant,ventilation;and 10% higher daily average temperature.
