Abstract:

【Objective】 To explore the synergistic mode of water and fertilizer in the hope of improving grape quality and efficiency under drip irrigation in extremely dry early area.【Methods】 Perennial seedless white grape was used as material, three conditions of low water and low fertilizer (low level), medium water fertilizer (medium level) and high water and high fertilizer (high level) were set in leaf-opening stage (vegetative growth stage).During the swelled period and mature period (reproductive stage), on the basis of the exhibition leaf stage, low water and low fertilizer (low level), medium water and medium fertilizer (middle level) and high water and high fertilizer (high level), a total of nine processing were set, with three repeat each processing to carry out the field synergy test to study their synergy effects on grape physical growth.【Results】 Under the coordination of water and fertilizer, the leaf area index showed an increasing trend with the increasing amount of water and fertilizer on the whole.Net photosynthetic rate, yield, hardness, soluble solids, reducing sugars and solid acid ratios are superior to those of other treatments in both vegetative and reproductive growth period, titratable acid and vitamin C content gradually increased with the increase of dosage of water and fertilizer.Appropriate water and fertilizer coordination could effectively promote the physiological growth of grapes.【Conclusion】 The total irrigation amount is 8,925 m3/hm2 and the total fertilizer amount is 240 kg/hm2.

摘要:

【目的】研究极端干旱区滴灌葡萄提质增效的水肥协同模式。【方法】以多年生无核白葡萄为材料,展叶期(营养生长期)设置低水低肥(低水平)、中水中肥(中水平)和高水高肥(高水平)3种配施处理,膨大期和成熟期(生殖生长期)在展叶期的基础上加设低水低肥(低水平)、中水中肥(中水平)和高水高肥(高水平)3种情况,共计9个处理,每个处理设3个重复。设置田间水肥协同试验,研究水肥协同对葡萄生理生长的影响。【结果】水肥协同下,葡萄叶面积指数随着水肥用量的增加整体呈递增的趋势,营养生长期和生殖生长期均为中水平水肥处理的净光合速率、产量、硬度、可溶性固形物、还原糖及固酸比要优于其他处理,可滴定酸含量和VC含量随着水肥用量的增加逐渐增加,适宜的水肥协同可以有效的促进葡萄的生理生长。【结论】葡萄最优水肥模型为全生育期中水平水肥处理,即总灌水量8 925 m3/hm2、总施肥量240 kg/hm2
