摘要: |
【目的】寻求最佳的设施延后栽培葡萄果实产量及品质的水肥调控阈值。【方法】通过田间试验,研究丰水、轻度胁迫、中度胁迫、重度胁迫4个灌水水平及高肥、中肥、低肥3个施肥水平处理对葡萄耗水规律、品质及产量的影响。【结果】灌水下限对耗水量、耗水强度、耗水模数、浆果膨大期和采摘期可滴定酸、采摘期花色苷、产量的影响均达显著水平,施肥水平对采摘期花色苷影响显著,对其它影响不显著,水肥互作效应对葡萄生殖期所测指标影响均不显著;适当的水分亏缺和肥料増施可促进产量增加,浆果成熟,改善浆果品质。【结论】中度胁迫(55%~60%田间持水量)中肥(N、P、K分别为161.92、53.97和44.98kg/hm2)(W3F2)组合处理的设施延后栽培葡萄产量较高,达38937.68kg/hm2,且品质较优,水分生产率较高,达7.86 kg/m3,是试区适宜葡萄高产栽培的水肥管理技术。 |

Abstract: |
【Objective】The objective is to find the best Fertilizer-water of the yield and quality of delayed cultivated grape. 【Method】 A field experiment was conducted to study Four irrigation thresholds and three fertilization levels comprised the fertigation treatments, aimed at the effects of fertilization and irrigation threshold on the water consumption regularity and quality of greenhouse grape under delayed cultivation. 【Result】The results were as follows: the effect of different irrigation threshold on the water consumption, water intensity of greenhouse grape 、Water consumption modulus、Titratable acid of picking period、Anthocyanin was significant; the effect of fertilizer on anthocyanin was insignificant; the effect of different irrigation threshold on measured indicators with the opposite. It can increase the grape yield、promote berry ripening and improve quality while fertilize and irrigate reasonably. 【Conclusion】Under the treatment of 55%~60%θf and the content of N,P,K were 161.92,53.97,44.98kg/hm2 respectively(W3F2),the yield of greenhouse grape under delayed cultivation can reach 38937.68kg/hm2, the quality was better and water use efficiency can reach 7.86 kg/m3 ,was the suitable water and fertilizer management techniques of experiment grapes. |
