| 摘 要： | 采用二次回归正交旋转组合设计,研究了灌水定额、氮肥和磷肥对保护地辣椒肥料氮和肥料磷经济利用效率的影响。研究表明:高量施肥时灌水定额增加能提高氮肥经济利用率,但在低量施肥情况下灌水定额增加却降低氮肥经济利用率。施氮、施磷、水氮交互作用和水磷的交互作用对磷肥经济利用效率的影响显著,其影响大小顺序为施磷>水磷互作>施氮>水氮互作,水磷互作对磷肥经济利率效率为正效应。 |

| Abstract: | By means of the quadratic orthogonal rotatory combination design,effects of water and fertilizers on rate of N and P2O5 utilization under the condition of capsicum cultivation in protected soil was studied.The result showed that increasing irrigating water quota could improve rate of N utilization under high amount fertilizer,but deceased rate of N utilization under low amount fertilizer.Effect of nitrogen,phosphate and interaction of irrigation and nitrogen fertilizer,interaction of irrigation and phosphate fertilizer were significant on rate of P2O5 utilization,in order phosphate fertilizer>interaction of irrigation and phosphate fertilizer>nitrogen fertilizer> interaction of irrigation and nitrogen fertilizer,effect of interaction of irrigation and phosphate fertilize was positive on rate of P2O5 utilization. |
| Keywords: | Capsicum annuum Protective ground Fertilizer Rate of utilization |
