摘要

摘要本实验的目的是使用具有不同光谱的灯具:钠灯-高压钠灯(HPS)和发光二极管(LED),评估温室中生长的黄瓜的补充照明效果。植物(黄瓜“Pacto”F1)生长在两个温室隔间中,有五种光处理:I–HPS+LED(顶部光,HPS LED作为中间照明),II–仅HPS作为顶部光,III–LED R(板上LED芯片(COB)类型,具有增加的红带水平),IV–LED W(LED COB类型,白色),V–LED B(LED COB类型,具有提高的蓝色光谱水平)。光照处理:HPS+LED和HPS在一个温室隔间中生长,其他三个光照处理(LED R(补充红光)、LED W(不补充红光)和LED B(补充红光光谱)在类似气候条件下在第二个隔间中生长。已知使用COB技术的LED灯是非常有效的光源。植物于2018年12月至2019年3月在矿棉板Grotop Master(100×15×10)中种植,一张垫子上有四株植物。它们被照射18小时(从早上5点到晚上11点),阈值(开启和关闭)设置为130 W。植物用完整的营养液进行滴灌。灌溉是基于加权系统进行控制的。在种植8周后,完成了对光照对黄瓜早期产量和质量影响的评估。研究表明,在8周的评估期内,通过用钠灯(HPS)照射植物,同时使用HPS和LED作为额外的照明行间,可以从一株植物中获得3.59kg。LED灯照射的植物产量因所用光谱的变化而变化,LED R、LED W和LED B的产量分别为3.30kg、3.90kg和3.25kg。所获得的结果表明,用HPS灯在顶部照明下生长的黄瓜“Pacto”F1的产量与LED W灯相似(即在没有额外补充红光(LED R)和蓝光(LED B)的情况下)。由于用于黄瓜补充照明的LED灯(用于顶部照明或作为中间照明的COB型)的良好效果和LED的高能效,与温室冬季栽培期间传统使用的HPS相比,该类型的灯具有良好的前景。

Effects of supplemental lighting using HPS and LED lamps with different light spectra on growth and yield of the cucumber (Cucumis sativus L.) during winter cultivation in greenhouse
Abstract The aim of the experiment was to assess the effects of supplemental lighting of cucumber grown in greenhouse using lamps with differentiated light spectra: sodium lamps – high-pressure sodium (HPS) and light emitting diodes (LEDs). Plants (cucumber ‘Pacto’ F1) were grown in two greenhouse compartments with five light treatments: I – HPS + LED (top light with HPS LEDs as interlighting), II – only HPS as top light, III – LED R (LED chips on board (COB) type with an increased level of red band), IV – LED W (LED COB type, white), V – LED B (LED COB type with an increased level of blue spectrum). Light treatments: HPS + LEDs and HPS were grown in one greenhouse compartment and the other three light treatments: LED R (red light supplementation), LED W (without additional supplementation) and LED B (red spectrum supplementation) in the second compartment in analogous climatic conditions. The LED lamps using COB technology are known to be a very efficient source of light. Plants were cultivated from December 2018 to March 2019 in mineral wool slabs Grotop Master (100 × 15 × 10) with four plants on one mat. They were illuminated for 18 h (from 5 am to 11 pm), setting the threshold value (on and off) at 130 W. The plants were drip-irrigated with a complete nutrient solution. The irrigation was controlled based on a weighting system. The assessment of the effect of lighting on early yield and quality of cucumbers was completed after 8 weeks of cropping. It was shown that it was possible to obtain 3.59 kg from one plant during the 8-week period of evaluation by illuminating plants with sodium lamps (HPS), while using HPS and LEDs as additional illuminated inter-rows 3.89 kg. The yield of plants illuminated by LED lamps varied depending on the variant of the spectrum used and was respective for LED R, LED W and LED B, 3.30 kg, 3.90 kg and 3.25 kg. The obtained results indicated that the yield of cucumber ‘Pacto’ F1 grown with HPS lamps at top lighting and at the same time using interlighting with LED lamps was similar to LED W lamps (i.e. without additional supplementation in the range of red (LED R) and blue (LED B) light). Due to good results of LED lamps (type COB for top lighting or as interlighting) used for the cucumber supplemental lighting and high energy efficiency of LEDs, the promising future for that type of lamps compared with traditionally used HPS during winter cultivation in a greenhouse was demonstrated.

期刊介绍: Folia Horticulturae is an international, scientific journal published in English. It covers a broad research spectrum of aspects related to horticultural science that are of interest to a wide scientific community and have an impact on progress in both basic and applied research carried out with the use of horticultural crops and their products. The journal’s aim is to disseminate recent findings and serve as a forum for presenting views as well as for discussing important problems and prospects of modern horticulture, particularly in relation to sustainable production of high yield and quality of horticultural products, including their impact on human health.
