3种架式对'新郁'葡萄栽培性状及果实品质的影响
Effects of 3 Trellis Systems on Cultivation Characters and Berry Quality of'Xinyu'Grape
摘要
Abstract
In order to screen and optimize the high quality and high efficiency cultivation trellis system of table grape in the northwest arid area,China,the'Xinyu'grape was used as experimental material,with 3 treatments including single dragon trunk shaping+horizontal leaf curtain(SDTS-H),inclined single dragon trunk shaping+horizontal leaf curtain(ISDTS-H),and inclined single dragon trunk shaping+vertical+horizontal leaf curtains(ISDTS-VH)were set,and the effects of 3 trellis systems on leaves photosynthetic characteristics,cluster micro-environment,fruit quality and economic benefits of'Xinyu'grape were analyzed.The results showed that the net photosynthetic rate was higher with ISDTS-VH than with SDTS-H by 7.73%,the water use efficiency was higher with ISDTS-H than with SDTS-H by 14.13%.Compared with SDTS-H,mean temperature with ISDTS-H and ISDTS-VH were higher than that with ISDTS-VH with 2.29 and 2.24℃,mean humidity were lower with ISDTS-H and ISDTS-VH than with ISDTS-VH by 4.96 and 3.85 percentage points,respectively.The daily average total radiation with ISDTS-H and ISDTS-VH were 2.66 and 1.31 times compared with SDTS-H.Grapes with ISDTS-H and ISDTS-VH ripened earlier than with SDTS-H,and the contents of soluble solids,anthocyanin,flavonoid,vitamin C and color index of red grape were significantly higher with ISDTS-H and ISDTS-VH fruits than with SDTS-H when berry ripening.The berry mass,flavonoid content and vitamin C content of SDTS-VH were the highest by 13.99 g,7.36 and 44.18 mg·kg-1,respectively,and the anthocyanin content was 1.22 mg·g-1 at the later stage of fruit ripen,the fruit quality was the best.Actual number of clusters similarity index and actual yield similarity index of SDTS-VH were the highest,with 0.73 and 1.06.Compared with SDTS-H,the cumulative hours with ISDTS-VH was reduced by 48.00%and the economic performance increased by 189.58%.Taken together,photosynthetic rate of ISDTS-VH was the highest,cluster micro-environment was the optimal,beneficial to quality formation and yield control,and economic performance was the highest.关键词
