| 摘要：【目的】探索南疆滴灌骏枣的产量及骏枣等级比例对水肥耦合的响应规律，为当地骏枣生产提供节水节肥优质的水肥配比模式。【方法】研究对象为南疆典型自压灌区昆玉市224团10a成龄骏枣，参考当地生产实践，以灌水量770 mm、施肥量1125 kg/hm2为对照，采用水（W1：540 mm，W2：630 mm，W3：720 mm）、肥（F1：562.5 kg/hm2，F2：810 kg/hm2，F3：1080 kg/hm2）双因素三水平试验，运用二元回归方程及归一化处理方法。【结果】灌水量对灌溉水分利用效率（IWUE）和骏枣单果重、纵横径、等级比例影响均达到显著性水平( P＜0.05），对产量影响达到极显著水平（P＜0.01）。施肥量对骏枣等级比例影响达到显著性水平（P＜0.05)，对肥料偏生产力（PFP)、单果重、纵横径影响达到极显著水平（P＜0.01）。水肥交互作用对骏枣产量、IWUE、PFP、骏枣等级比例（除四级果率外）影响均达到极显著水平（P＜0.01）。骏枣产量、IWUE均为W2F3处理最高，与CK具有显著性差异（P＜0.05）。骏枣单果重、纵横径为W2F2处理最优。骏枣特级、一级、三级与四级果率均为W2F2处理最优，W2F2除了在一级果率中与W2F3差异不显著，其余均具有显著性差异（P＞0.05）。【结论】适宜水肥配比量是提高骏枣产量、外观品质、果品等级比例的关键因素。通过分析不同水肥配比与产量、骏枣等级比例数学模型，综合考虑骏枣提质增效目标，提出适宜水肥配比区间为灌水量（639.21~642.85 mm），施肥量（N 374.38~384.02 kg/hm2、P2O5 187.19~192.01 kg/hm2、K2O 280.79~288.02 kg/hm2）。 |

| Abstract:【Objective】To explore the yield of drip irrigated junzao in southern xinjiang and the response law of grade proportion of junzao to water and fertilizer coupling, and to provide-saving and fertilizer-saving high quality water and fertilizer ratio mode for local junzao production.【Method】The research object was 10-year-old Junzao jujube in 224 regiment of Kunyu City, a typical self-pressure irrigation area in southern Xinjiang. Referring to the local production practice, the irrigation amount of 770 mm and the fertilization amount of 1125kg/hm2 were used as the control. 540 mm, W2; 630mm, W3 ; 720 mm), fertilizer ( F1 ;562.5 kg /hm2,F2;810kg/hm2, F3;1080kg /hm2) two-factor three-level test, using binary regression equation and normalization method.【Result】The effects of irrigation amount on irrigation water use efficiency ( IWUE ) and single fruit weight, vertical and horizontal diameter and grade ratio of Junzao reached significant levels ( P < 0.05 ), The effect of fertilizer application rate on the grade ratio of Junzao reached a significant level ( P < 0.05 ), and the effect of fertilizer partial productivity ( PFP ), single fruit weight, vertical and horizontal diameter reached a very significant level ( P < 0.01 ).The interaction of water and fertilizer on Jun jujube yield, IWUE, PFP, Jun jujube grade ratio ( except the fourth grade fruit rate ) reached a very significant level ( P < 0.01 ).Jujube yield and IWUE were the highest in W2F3 treatment, and had significant difference with CK ( P < 0.05 ). The special grade, first grade, third grade and fourth grade fruit rate of junzao were the best in W2F2 treatment. The single fruit weight, vertical and horizontal diameter of Junzao were the best in W2F2 treatment.Except for the first grade fruit rate, the difference between W2F2 and W2F3 was not significant, the rest had significant difference ( P > 0.05 ).【Conclusion】Suitable water and fertilizer ratio is the key factor to improve the yield, appearance quality and fruit grade ratio of Junzao.By analyzing the mathematical models of different water and fertilizer ratios, yield and grade ratio of Junzao, and comprehensively considering the goal of improving quality and efficiency of Junzao, the suitable water and fertilizer ratio range was proposed as irrigation amount ( 639.21-642.85 mm ) and fertilization amount ( N 374.38-384.02 kg / hm2, P2O5 187.19-192.01 kg / hm2, K2O 280.79-288.02 kg / hm2 ). |
