| 中文摘要: |
| ：安塞试验站2005~2006连续两年采用N、P、K三因素最优设计,田试不同施肥量对南瓜Vc和干物质两项营养品质的影响,探讨南瓜优质的N、P、K肥效反应模式。结果表明,N肥对南瓜Vc含量的影响最大,K肥对干物质含量的影响最大,N与P交互作用和N与K交互作用对南瓜Vc、干物质含量影响显著。筛选出南瓜优质的较佳施肥量为:施氮9095 kg/hm2,施磷7580 kg/hm2,施钾2530 kg/hm2。N∶P2O5∶K2O=1.00∶0.83∶0.28。 |
| 英文摘要: |
| 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． |
