摘　　要：为掌握红色遮阳网对番茄生长及果实品质的影响,在塑料大棚的基础上,设置了红色遮阳网覆盖与白色无滴膜覆盖(对照)的田间大区试验,分析了不同处理的光谱组分、番茄生长、产量和品质。结果表明:红色遮阳网覆盖降低了蓝光光合有效辐射,增加了红光/蓝光比例和红光/远红光比例。红色遮阳网覆盖后,番茄果实可溶性固形物含量、糖酸比、果皮亮度、红色度分别比对照提高了10.2%、17.3%、28.9%和42.7%,同时番茄产量和产值分别增加了15.4%和17.9%;与对照相比,红色遮阳网覆盖对番茄果形指数、维生素C含量、可溶性糖含量、可滴定酸含量、氮磷钾含量等均没有显著影响。结果可知红色遮阳网覆盖可能通过减少蓝光透过率提高红蓝光比例,促进番茄产量、果实风味品质和外观品质提升。In order to grasp the effect of red sun shading net on the growth and fruit quality of tomatoes,on the basis of plastic greenhouse,the large-plot field experiments with the red sun shading net coverage and white drip-free film coverage(the control group)were conducted to analyze the spectral components,tomato growth,yield and quality under different treatments.The results showed that the coverage of red sun shading net reduced the photosynthetic active radiation,increased the ratio of red light to blue light and the ratio of red light to far-red light.After the red sun shading net was covered,the content of soluble solid,the ratio of sugar to acid,the brightness and redness of peel increased by 10.2%,17.3%,28.9%and 42.7%,respectively,compared with the control group,while the yield and output value of tomato increased by 15.4%and 17.9%,respectively.Compared with the control group,the red sun shading net coverage had no significant effect on the fruit shape index of tomato,vitamin C content,soluble sugar content,titratable acid content,and the contents of nitrogen,phosphorus and potassium.The results showed that the coverage of red sun shading net may increase the proportion of red light to blue light by reducing the blue light transmittance,and promote the improvement of tomato yield,fruit flavor quality and appearance quality.
