| 摘要: |
| 以新疆环塔里木盆地阿克苏红旗坡农场5年生红枣树为研究对象，在全年施肥量（纯N 675 kg·hm-2、P2O5 540 kg·hm-2、K2O 135 kg·hm-2）一定条件下，通过田间施肥试验，研究氮磷钾不同配施比例对红枣树生理特性及果实品质的影响。结果表明：萌芽前期施纯N、P2O5、K2O肥270、180、67.5 kg·hm-2，开花期施纯N、P2O5肥202.5、180 kg·hm-2，果实膨大期施纯N、P2O5、K2O肥202.5、180、67.5 kg·hm-2的综合效果佳，有利于枣树茁壮生长和果实品质的提高。与常规施肥相比，红枣树开花期、幼果期、果实膨大期和成熟期的叶绿素SPAD值增幅分别为6%、4%、5%和11%；各测量时段09∶00、11∶00、13∶00、15∶00、17∶00、19∶00的净光合速率分别提高11%、14%、16%、82%、15%、44%；气孔导度分别提高34%、25%、30%、132%、129%、96%；胞间CO2浓度分别降低13%、22%、14%、18%、24%、15%；蒸腾速率分别降低50%、45%、28%、24%、33%、52%；果实维生素C、还原糖、蛋白质含量最高，分别为6.41 mg/100g、19.33%和2.53%，差异显著。 |

| Abstract: |
| Using 5-year old trees in southern Xinjiang, a field experiment was conducted to measure the effect of N∶P∶K ratio on physiological traits and fruit quality of Zizyphus jujube trees. Results showed the favorable effect on jujube tree growth and fruit quality of applying N (270 kg·hm-2), P2O5 (180 kg·hm-2) and K2O(67.5 kg·hm-2) at early stage, P2O5 (202.5 kg·hm-2) and K2O (180 kg·hm-2) at flowering stage and N (202.5 kg·hm-2), P2O5 (180 kg·hm-2), and K2O (67.5 kg·hm-2) at fruiting stage. Compared with conventional method, chlorophyll SPAD of each period for combined application treatment for the four periods, i.e., flower stage, young fruit stage, fruit expanding stage, and fruit havest stage was increased by 6%, 4%, 5%, and 6%. Net photosynthetic rate of each period at the time 09∶00, 11∶00,13∶00, 15∶00, 17∶00 and 19∶00 was increased by 11%, 14%, 11%, 82%, 15%, and 44%, stomatal conductance by 34%, 25%, 34%, 132%, 129%, and 96%, intercellular
CO2 by 13%, 22%, 14%, 22%, 24% and 15%, and transpiration rate by 50%, 45%, 28%, 45%, 33% and 52%. In addition, fruit vitamin C, reducing sugar, and protein content were 6.41 mg·100g-1, 19.33% and 2.53%, respectively, being significantly different from those of conventional fertilization. |
