摘　　要：以"一品天下208"甜瓜为试材,以土壤栽培及当地常规施肥为对照(CK),采用基质盆栽,研究了低、中、高3个施肥量处理(T1、T2、T3)对温室甜瓜光合特性、产量及品质的影响,以期探索适合关中地区温室甜瓜生产的合理施肥量,实现高产高效。结果表明:一定范围内,随着施肥量的增加,各光合特性指标逐渐增强,T2、T3处理的净光合速率差异不显著;与对照相比,T1、T2、T3处理的产量分别提高了11.2%、28.7%、16.4%;不同施肥量对甜瓜品质影响显著,且T2处理品质最佳。综上,T2处理下光合作用强且可得到较高的产量和较好的品质,故推荐采用基质盆栽,且施肥量为1hm^2施N 225kg、P_2O_5140kg、K_2O 150kg。With‘Yipin Tianxia 208＇muskmelon as test material and soil cultivation and traditional amount of fertilizer as control（CK）,three fertilizer rates including low fertilizer（T1）,middle fertilizer（T2）and high fertilizer（T3）with potted substrate cultivation were set,and effect of different rates combination of N,P and K fertilizers on the growth,yield and quality of muskmelon were investigated.The objective of this research was to seek the optimal application rate of fertilizer for the high yield and high efficient production of greenhouse muskmelon in Guanzhong area.The results showed that within a certain range,the photosynthetic characteristics increased with increasing of fertilizer amount,however,no significant difference was observed between the net photosynthetic of T2 and T3;compared to the control,the yield of T1,T2,T3 were increased by 11.2%,28.7%and 16.4%;the different fertilizer rates had significant effect on the quality of muskmelon and overall the T2 was the best.Comprehensive consideration indicated that under the condition of T2,it could obtain the higher yield and better quality.Therefore,the potted substrate cultivation was recommended and the reasonable fertilizer amount was：N 225kg/hm^2,P2O5 140kg/hm^2 and K2 O150kg/hm^2.
