以设施栽培的红富士葡萄为试材,研究铺设0.75和1.00m幅宽的特卫强对设施内小环境及葡萄果实品质的影响。结果表明,设施内铺设特卫强显著提高了树冠中下层的光照强度,降低了夏季土壤温度。其中,铺设0.75和1.00m幅宽特卫强,距离地面60~140cm冠层处的光照反射率分别为对照的2~3和3~4倍;浆果成熟期,5~25cm土层的日均温度降低了1.2~2.3℃。铺设特卫强在加快葡萄成熟的同时,提高了果实内在品质并促进果皮着色,从而显著提高了消费者对葡萄的综合评价,增强了消费者对红富士葡萄果实的喜好程度。本研究还表明,铺设1.0m幅宽的特卫强对红富士葡萄的作用效果更明显;设施内要保证红富士着色率达到60%以上,应使667m2产量不超过1 375kg。
The cultivation of Fuji grapes as a test material to study the deployment of 0.75 and 1.00m width Tyvek strong impact on facilities within the small environment and grape fruit quality. The results showed that the laying of Tyvek in the facility significantly increased the light intensity of the middle and lower canopy and decreased the soil temperature in summer. Among them, 0.75 and 1.00m wide Weiwei strong, light reflectance at the canopy 60 ~ 140cm from the ground were 2 ~ 3 and 3 ~ 4 times that of the control, respectively. During the ripening period of the berries, the daily average of 5 ~ 25cm soil layer Temperature decreased by 1.2 ~ 2.3 ℃. The laying of Tyvek accelerates grape ripening at the same time, improve the inherent quality of the fruit and promote the skin coloring, which significantly improves the consumer’s comprehensive evaluation of grapes and enhance consumer preferences of Fuji grape fruit. The study also shows that laying 1.0m width Tyvek strong effect on Red Fuji grapes more obvious; facilities to ensure that the Red Fuji color more than 60%, 667m2 should yield no more than 1 375kg.
