摘要:
【目的】研究不同类型补光灯对草莓植株光合特性、生长、产量及品质的影响,为草莓设施栽培补光灯的选择提供参考。【方法】以‘红颜草莓’为供试材料,在温室大棚进行草莓补光试验,共设5个类型的补光灯处理,分别为激光生长灯(T1)、红蓝光配比为4.9∶1的LED灯(T2)、红光荧光灯(T3)、红蓝光配比为3∶1的LED灯(T4)和高压钠灯(T5),以不补光为对照,测定不同补光灯处理下草莓植株的光合参数、形态指标及草莓果实的产量和品质。【结果】红蓝光配比为4.9∶1的LED灯和红光荧光灯更有利于提高草莓植株的光合参数,红光荧光灯下草莓植株的营养生长最旺盛,但最终产量并不高;红蓝光配比为4.9∶1和3∶1的LED灯以及高压钠灯对促进草莓提前成熟的效果最好,果实单果质量和最终产量也以红蓝光配比为4.9∶1和3∶1的LED灯下最高;高压钠灯处理下草莓果实可溶性固形物和可溶性糖含量均最大,果实VC含量在红蓝光配比为3∶1的LED灯下最大。【结论】红蓝光配比为4.9∶1的LED灯最有利于促进草莓植株的光合和生长,提高果实的产量和品质。综合考虑认为,红蓝光配比为4.9∶1的LED灯可作为冬春季节寡日照地区大棚草莓较好的补光光源。

Effects of supplement light type on photosynthetic characteristics and yield of strawberry in greenhouse
QIAN Shuting,LI Jianming
Abstract:
【Objective】The study investigated the effects of different supplemental lighting types on photosynthesis,growth,yield and quality of strawberry to provide reference for selecting supplemental lighting for strawberry.【Method】Taking Benihoppe strawberry variety as experimental material,different supplemental lighting types were tested to examine the effects on morphology,photosynthetic parameter,yield and quality of strawberry in greenhouse.Five treatments were set including plant laser light (T1),LED plant light (R/B=4.9) (T2),red fluorescent lamp (T3),LED plant light (R/B=3) (T4),high pressure sodium lamp (T5) and without lamp (CK).【Result】Red fluorescent lamp and LED plant light with the red/blue photons ratio of 4.9∶1 were the best to improve the photosynthetic parameter of strawberry.Red fluorescent lamp had the best nutritional growth of plant,but the yield was not high. High pressure sodium lamp and LED plant lights with the red/blue photons ratios of 4.9∶1 and 3∶1 caused the most advanced fruit ripening.Fruit weight and the final output were the highest under LED plant light with the red/blue photons ratios 4.9∶1 and 3∶1.The contents of soluble solid and soluble sugar were the highest under high pressure sodium lamp, while the highest vitamin C content was obtained under LED plant light source with the red/blue photons ratio of 3∶1.【Conclusion】LED plant light with the red/blue photons ratio of 4.9∶1 was the best to the improve the photosynthetic growth of the plant,quality and yield of strawberry.
