| 摘要: |
| 【目的】摸清不同水肥用量对宁夏中部干旱区枸杞果实糖类和类胡萝卜素量的影响。【方法】通过大田试验，以补灌量（X1）、施氮量（X2）、施磷量（X3）和施钾量（X4）为试验因素，采用4因素6水平的均匀设计方法，研究了不同水肥条件对枸杞果实总糖、多糖和类胡萝卜素量的影响。【结果】 ①单因素对枸杞果实总糖量影响显著，各单因素对枸杞果实总糖量的影响顺序为：X1>X4>X3>X2；②二因素交互作用对枸杞果实总糖影响规律为X3X4>X2X4>X1X2>X1X3>X1X4>X2X3，各因素交互作用可提高枸杞果实总糖含量；③二因素交互作用对枸杞果实多糖影响规律为X2X4>X1X3>X1X2>X3X4>X1X4>X2X3；各因素交互作用可提高枸杞果实多糖量；④二因素交互作用对枸杞果实类胡萝卜素影响规律为X3X4>X1X3>X1X2>X2X3>X1X4>X2X4；各因素交互作用可提高枸杞果实类胡萝卜素量。【结论】 试验条件下，枸杞滴灌最优的水肥管理方案为补灌量1 700~2 090 m3/hm2、施氮量240~342 kg/hm2、施磷量19~95 kg/hm2、施钾量130~171 kg/hm2。 |

| Abstract: |
| 【Objective】 Water and soil nutrients modulate plant growth and the objective of this work is to experimentally study the combined impact of water and fertilizer on the contents of sugar and carotene in wolfberry grown in arid region under drip irrigation. 【Method】 Field experiments designed using the four-factor and six-level uniform method were conducted, and irrigation (X1), nitrogenous fertilizer (X2), phosphate fertilizer (X3) and potash fertilizer (X4) were considered as the impact factors.【Result】 ①Each single factor had a significant effect on the content of total sugar in the fruits, and their impact was ranked in X1>X4>X3>X2. ②The two-factor interactive impact was ranked in X3X4>X2X4>X1X2>X1X3>X1X4>X2X3 based on their effects on total sugar content. ③For their impact on polysaccharide content, the two-factor coupling was in the order X2X4>X1X3>X1X2>X3X4>X1X4>X2X3. ④For impact on carotenoid content, the two-factor coupling was ranked in X3X4>X1X3>X1X2>X2X3>X1X4>X2X4. 【Conclusion】 The optimal fertigation is 1 700~2 090 m3/hm2 of water, 240~342 kg/hm2 of nitrogen, 19~95 kg/hm2 of phosphorous, and 130~171 kg/hm2 of potash. |
