Abstract: In order to provide theoretical basis for the safe and high nutrition quality Momordica charantia，the field experiment and instrument analytical method were adopted to study the effects of the plant nutrition on the field and quality of Momordica charantia L. The results showed that the plant nutrition had higher yield and quality than applying water（contrast）.Compared with the contrast，one single fruit weight，yield per plant， flavonoids content，the soluble sugar content，the vitamin C content and polypeptides content of applying the plant nutrition increased by 14.5%，21.9%，17.9%，40.1%，28.7% and 44.5% respectively，and the nitrite content reduced 27.9%. In general，proper amount of the plant nutrition could promote growth，increase the yield and improve the quality of Momordica charantia L.

Key words: plant nutrition, Momordica charantia L., yield, quality
