摘要
以5年生藤稔葡萄为试材,研究了内外膜不同间距对双膜大棚葡萄棚内温度及生长、坐果的影响。试验结果表明：随着内外膜间距的增加,棚内温度的提升和积温增加效果更好,间距60 cm的日均温度比40 cm和20 cm分别提高0.77℃、1.67℃,积温分别增加73.6℃和158.5℃,萌芽期、成熟期也更早。内外膜60 cm间距的大棚葡萄在5月6日上市,较40 cm和20 cm间距的葡萄分别提早上市4 d和8 d,种植效益也有明显增加;棚膜40 cm间距的葡萄其萌芽率、坐果率、粒质量、可溶性固形物含量及着色度等指标均为各处理最高,综合品质最好。故双膜栽培的内外膜间距以40~60 cm为宜。
The effects of different spacing between the inner and outer membrane on the temperature, growth and fruit set of 5-year-old Fujiminori grapevine in greenhouse with doublefilm were studied. The result showed that： with the increase of distance between the inner and outer membrane, the effect of temperature rise and accumulated temperature in greenhouse were better. Compared with 40 cm and 20 cm treatments, the daily average temperature of 60 cm treatment was increased by 0.77 ℃ and 1.67 ℃ respectively, and the accumulated temperature increased by 73.6 ℃ and 158.5 ℃. In 60 cm treatment, the phenological phases such as budbreak and mature period were ahead of schedule, and the harvest was advanced to May 6th, respectively 4 d and 8d earlier compared with 40 cm and 20 cm treatments, so the benefits were significantly improved correspondingly. However, the germination rate, fruit-setting rate, fruit firmness, color, soluble solids content and other quality indicators of 40 cm treatment were the highest in all treatments. Therefore, the spacing of double-film culture take 40~60 cm as proper.
