Abstract

Land for agriculture is becoming limited in urban areas and the concept of vertical farming could help increase land productivity. Therefore, this study was conducted to investigate the potential of vertical farming on sunlight availability for lettuce (Lactuca sativa L.) production in the greenhouse system. The experimental design was completely randomized design with two different farming systems: Horizontal and vertical farming systems. Ten planting shelves including five horizontal shelves (HS) and five vertical shelves (VS) with three vertical levels as upper (VS_U), middle (VS_M) and lower (VS_L) were constructed. Two lettuce varieties, âGreen Oakâ (L. sativa var. crispa) and âGreen Cosâ (L. sativa var. longifolia), were selected for comparative measurement. Lettuce was planted in both HS and VS systems. Photosynthetically photon flux density (PPFD) was continuously monitored throughout lettuce growing period. Lettuce height and canopy width were measured weekly. Leaf fresh weight (FW) and dry weight (DW) were also evaluated. The averaged PPFD values were 245, 217, 158 and 147 Î¼mol m-2 s-1 for HS, VS_U, VS_M and VS_L, respectively. Higher values of height and canopy width were observed on HS in comparison to VS. Values of FW and DW on HS were significantly higher as compared to VS. In addition, higher plant growth occurred from upper to lower levels on VS while lower FW and DW were observed from top to bottom. Plant densities of VS (24 plant m-2) were 1.5 times higher than HS (16 plant m-2). Light use efficiency was also pointed out that VS (0.46 g mol-1) tended to have better values in comparison to HS (0.28 g mol-1).

垂直种植:一种潜在的生菜种植方式

城市地区的农业用地越来越有限，垂直农业的概念可以帮助提高土地生产力。因此，本研究旨在探讨温室系统中垂直种植对生菜(Lactuca sativa L.)生产的日光利用潜力。试验设计为完全随机设计，采用水平和垂直两种不同的耕作系统。构建了10个种植货架，包括5个水平货架(HS)和5个垂直货架(VS)，垂直层次分别为上(VS_U)、中(VS_M)和下(VS_L)。以莴苣品种’绿橡’(L. sativa var. crispa)和’绿花莴苣’(L. sativa var. longgifolia)为研究材料进行比较。莴苣在HS和VS两种系统中种植。在整个生菜生育期对光合光子通量密度(PPFD)进行连续监测。每周测量生菜高度和冠层宽度。测定叶片鲜重(FW)和干重(DW)。HS、VS_U、VS_M和VS_L的平均PPFD值分别为245、217、158和147 Î¼mol m-2 s-1。高、冠宽在高、冠宽上均显著高于高，高、冠宽在高、冠宽上均显著高于低，高、冠宽在高、冠宽上均显著高于低。VS(24株m-2)的密度是HS(16株m-2)的1.5倍。光利用效率还指出，VS (0.46 g mol-1)的值往往优于HS (0.28 g mol-1)。
