摘要

植物工廠是指在設定的環控及生產管理程序下，以工業模式進行全年無休植物生產的系統，是精準農業與設施栽培的極致。在台灣，精準農業與設施栽培之研究已有許多成就，然而針對溫室或GSA（Greenhouse with Solar Light and Supplementary Artificial Light）型植物工廠之補光系統的研究並不多，為解決溫室或GSA型植物工廠使用太陽光不穩定問題，本研究建立以日累積光合作用量為補光依據之補光系統，該系統採夜間補光方式並具有自動移動與自動燈具升降之功能。本研究進行系列實驗得到皺葉萵苣之光合作用率迴歸公式供系統使用，以建立之補光系統於國立台灣大學生農學院太陽光與人工光源併用型植物工廠內進行補光實驗，依據日累積光合作用量（Daily Photosynthesis Integral, DPI）進行皺葉萵苣栽培上的補光。研究結果顯示其乾重及鮮重較僅使用太陽光栽培之皺葉萵苣分別增加了133%及145%，並與使用完全人工光栽培之皺葉萵苣乾重及鮮重無顯著差異。

Plant factory can be defined as a plant production system to provide agricultural produce of quality with stable, year-round, mass productions by controlled conditions according to the production schedule. From the view of technology, plant factory could be regarded as the ultimate extension of protective cultivation and quality agriculture. In Taiwan, there have been many achievements in quality agriculture and protective cultivation in the past years. However, the work on supplementary artificial lighting system for greenhouses and GSA plant factories has not been much addressed. To solve the problem of instability in solar used in greenhouses or GSA plant factories, the study developed an automatic supplementary lighting system based on daily photosynthesis integral (DPI) during night time with the functions of automatic gantry movement and automatic height adjustment of lamps. The photosynthetic characteristics of lettuce (Lactuca sativa L. var. crispa L) were obtained by experiments in order to integrate with supplementary lighting system. Supplemental lighting experiments were conducted at NTU GSA plant factory by using supplementary lighting system based on the investigated daily photosynthesis integral. The results showed that the dry weight and fresh weight of lettuce grown with both of sunlight and supplementary light were increased by 133% and 145% respectively compared to those with only sunlight; and it had no significant difference when compared to the group of using only artificial light with the same daily photosynthesis integral.
