中文摘要: 葡萄是一种对水分十分敏感的果树,在我国大陆性季风气候下,合理的水分管理措施对葡萄产业的发展十分重要。笔者综述了在滴灌方式下,作为研究热点的2种灌溉制度--调控亏缺灌溉(PRD)和交替根区灌溉(APRI)的技术特点、对葡萄生长发育的影响以及在生产中实施的注意事项,为生产者们制定合理的灌溉制度提供了理论依据。制定合理的调控亏缺灌溉和交替根区灌溉制度可以减小植株无效的营养生长,促进根系生长,解决滴灌方式下根系上浮的问题,同时提高果实品质,维持甚至提高产量,还有利于树体营养的贮存。其中交替根区灌溉技术相对容易掌握,对产量影响不大,对生产者而言风险较小,适宜作为今后研究和应用的重点。此外,2种灌溉制度之间的系统比较也应作为今后的研究重点。
英文摘要: Grapes are among the earliest domesticated fruit species and the most economically important fruit crop worldwide nowadays. According to Food & Agriculture Organization (FAO), viticultural area in China had reached 1.96 million acres in 2014. As a perennial deciduous fruit tree, grapevine is quite sensitive to water. Therefore, developing efficient water management strategies that are suitable for our unique climate in China is significantly important; and it has been the focus of massive researches due to increasing water shortage, climate change and global warming worldwide. The aim of this review is to help growers setting up a practical irrigation program that can inhibit vegetative growth of the grapevine, facilitate root development, improve fruit quality, maintain or even enhance yield, reserve nutrition, and ensure winter hardiness. This review summarized two irrigation programs under drip irrigation- regulated deficit irrigation (RDI) and alternate partial root zone irrigation(APRI), from following aspects: 1, the time point when the two programs should be applied on the vines and to what extent the water deficit is appropriate. 2, how the two programs influence the soil water content, soil structure, and root systems. 3, how the two programs influence the growth and development of grapevine including shoot growth, leaf area index and photosynthesis; and how they influence fruit yield and quality. 4, the two irrigation programs are relatively new and their applications in commercial vineyards in China haven't been well-established. It is necessary to list the precautions to avoid production loss or quality decline. The timing point for DRI is critical. To maintain the yield of table grape, the water deficit should be applied before fruit set; it should be irrigated fully during flowering and berry enlarging periods. But for wine grapes, deficit could be applied during veraison. The degree of deficit is important as well. Conventionally, midday leaf water potential is used in determining water needs. During non-deficit irrigation, full irrigation should be applied when the midday leaf water potential drops below -1.0 MPa. While, during RDI, the leaf water potential should be maintained between -1.2 and -1.4 MPa in order to avoid detrimental influences on the fruit quality and yield. There were not enough studies on the influences of RDI on root development which should be paid more attention in further studies. Proper application of RDI can improve fruit quality. When applying RDI in a commercial vineyard, it is necessary to make sure that the soil samples can reasonably represent the whole area. The optimum dripper distance is about 50-60 cm. All in all, there are three key elements in practical application of RDI: the timing, duration and degree of deficit. For APRI, the timing is relatively flexible but the interval is quite critical. Studies show that the interval can be 10-14 days in temperate climate areas while 7 days in hot climate areas. Take transpiration rate and soil texture into consideration first. Drip irrigation combined with APRI can increase soil permeability, facilitate root development, decrease evaporation between plants and thus increase water-use efficiency. Similar to DRI, APRI also has a significant effect on improving the fruit quality while maintaining yield.
