不同颜色遮阳网覆盖对越夏番茄产量、光谱及品质的影响

为研究不同颜色遮阳网覆盖对越夏番茄生长特性和果实品质的影响,设计了4组处理,以不覆盖遮阳网作为对照,分别是:银白色(30%)、蓝色(30%)、紫色(30%)、灰色(30%)和CK,系统分析了越夏番茄植株长势、果实品质、遮阳网覆盖下的相对光谱、植株根系以及产量等指标。结果表明,番茄经不同颜色遮阳网覆盖后相对光谱值略有变化;各处理的单株根总长、单株根总表面积、单株根总体积、产量、单果重和叶绿素含量均明显高于对照番茄;其中又以蓝色遮阳网覆盖的效果最佳,其单株根总长、单株根总表面积、单株根总体积、产量、单果重和叶绿素含量分别比对照提高134.41%、151.32%、231.80%、28.10%、44.80%和37.50%。

Effect of sun-shading covering with different colors net on the yield, spectrum and quality of oversummering tomato

In order to study the effects of different color sunshade mulching on summer tomato growth characteristics and fruit quality, four treatments were designed, which were covered with silver (30%), blue (30%), purple (30%), gray (30%) shading net, respectively, taken uncovered sunshade net as the control, and the plant growth of summer tomato plant, fruit quality, relative spectra of summer tomato covered with sunshade net, plant root system and yield were systematically analyzed. The results showed that the relative spectral value of tomato was slightly changed after covering with different color shading nets; the total root length, total surface area, total root volume, yield, fruit weight and chlorophyll content in different treatments were different; the amount of tomato was significantly higher than that of the control, and the blue shade net had the best effect: the total length of single plant root, total surface area of single plant root, total volume of single plant root, yield, single fruit weight and chlorophyll content were respectively 134.41%, 151.32%, 231.80%, 28.10%, 44.80% and 37.50% higher than the control group.
