| 摘 要： | 通过田间试验研究不同施氮量对茄子产量及经济效益的影响。结果表明，氮肥施用量对茄子的产量和效益影响显著，施氮量12kg／667m2时产量和经济效益最高，继续增加施氮量，产量反而下降，产投比随氮肥用量的增加而逐步下降。回归统计分析表明，施氮量12kg／667m2时，茄子产量与理论值基本一致，表明在此施氮条件下经济回收率最大。

| Abstract: | The effects of different nitrogen application rate on eggplant yield and economic benefit were studied through field ex- periment. The result showed that nitrogen fertilizer application significantly affected the yield of eggplant, the yield and the e- conomic benefit are supreme when 12 kg/667m2 nitrogen fertilzier application rate was applied, then the yield decreased with the increase of nitrogen fertilizer application, and the input--output ratio decreased gradually with the increase of nitrogen fertilizer application. Regression statistical analysis showed that, the yield of eggplant is accord with the theory with the 12 kg/667m2 ni- trogen fertilizer application rate, which has the largest economic recovery under the condition of nitrogen fertilizer application rate. |
