Abstract:

This paper studied the effects of different fertilization treatments on the fruit quality of greenhouse cherry tomato under facility cultivation conditions in south of China. The results were as follows: Under only applying inorganic nitrogenous fertilizers,Vc and nitrate content increased with the applied nitrogen amount,but reducing sugar and organic acid content increased first and decreased afterwards;application in proportion of inorganic nitrogenous fertilizers and bio-organic fertilizers was more beneficial to the Vc, reducing sugar ,organic acid increasing and nitrate decreasing of cherry tomato than only applying inorganic nitrogenous fertilizes; application in proportion of nitrogenous, phosphatic and potassic fertilizers and combining with applying bio-organic fertilizers was the best for Vc content increasing, especially, the effects was best under conditions of 40kg/667m2 applied nitrogen amount，2:1:1 nitrogen, phosphate, and potassium and 50kg/667m2 applied bio-organic fertilizer amount，the Vc content was highest, nitrate content was lowest and reducing sugar ,organic acid content showed a significant improvement.
