| Abstract: |
| The experiment for optimum design of N P and K fertilization model was conducted to study the influence of different fertilization rate to pumpkin dry matter quality and Vc content．The results showed that N had significant effect on Vc content of pumpkin and P had significant effect on the content of dry matter while the influence of N and P N and K correlation to pumpkin dry matter and Vc content was remarkable．The optimum amount of N P and K fertilization was nitrogen N 90～95 kg／hm2 phosphorous P2O5 75～80kg／hm2 and potassium 25～30 kg／hm2．The N∶P2O5∶K proportion was 1∶0．83∶0．28． |
