| 摘 要： | 目的:研究大田条件下N、P、K肥料不同配比对盾叶薯蓣根茎产量及薯蓣皂苷元含量的影响.方法:采用肥料单因素正交试验,SPSS11.5统计软件包统计分析.结果:N、P、K可不同程度提高盾叶薯蓣根茎产量及薯蓣皂苷元含量,其中N、K对产量影响达到极显著水平(P＜0.01),P肥达到显著水平(P＜0.05),N、P、K单施对含量影响未达到显著水平(P＞0.05);3种肥料配施以N肥对薯蓣皂苷元含量影响达到显著水平(P＜0.05).表明肥料对薯蓣皂苷元含量影响的顺序为N＞K＞P,对根茎产量影响的顺序为K＞N＞P,综合最优组合为N2K1P2.结论:适当配比的N、P、K肥料可以同时提高盾叶薯蓣根茎产量与薯蓣皂苷元含量. |

| Abstract: | Objective:A field experiment was conducted to investigate the different effects of various applying ratios of nitrogen (N),potassium (K) and phosphate (P) on diosgenin content and Rhizoma yield of Dioscorea zingiberensis Method:Experiment was conducted with both one factor and orthogonal design, and data was analyzed statistically on SPSS 11 5 Results:Compared with the control groups,the yield of rhizome was significantly increased by N (P<0 01),K(P<0 01),P(P<0 05) The content of diosgenin has no obvious increase (P> 05) by individual application of N, P and K,while changed significantly (P<0 05) by the combination of proper levels of N, P, K Conclusion : The degree of effect on diosgenin content was ranged with N>K>P,while on output of dioscorea rhizome was K>N>P,and the combination of N 2K 1P 2 was superior to others |
| Keywords: | Dioscorea zingiberensis Wright Applying ratios of NPK combined Diosgenin content Rhizome yield |
