Abstract:: ‘Hang-eggplant 2010’was taken as material.The conventional fertilization,and four integrated water and fertilizer irrigation treatments (fertilizing amount of 675，600，525，480 kg·hm-2) were set up to carry out the topdressing experiment of eggplants.The quality and yield of eggplant were studied.The results showed that in comparison with conventional fertilization,the fruit weight,length and diameter increased by 13.1%-35.1%,15.0%-43.8%,11.1%-33.3% in integrated water and fertilizer irrigation.The yield,production value and net income in integrated water and fertilizer irrigation treatments increased by 3.2%-8.5%,3.4%-9.9% and 15.5%-26.5% respectively,in comparison with conventional fertilization treatment.However,there were no significant differences in contents of fruit nitrogen,phosphate and potassium under different treatments.Among the five treatments,fertilizing amount of 675 kg·hm-2 was suitable for fertilization of eggplant.
