Plant Production process, floor plan, and layout of PFAL
Plant Factory, 2020Co-Authors: Toyoki KozaiAbstract:Abstract The floor plan of a Plant factory with artificial lighting (PFAL) and layouts of equipment and culture (or cultivation) beds are designed to achieve efficient operations by workers and smooth flows of materials such as the Plants and supplies in the Plant Production system. In addition, it is essential that the PFAL be designed and operated to maintain a high level of sanitation for food safety. However, PFALs are relatively new Production systems, so the optimum Production technologies have not yet been established and there is much room for improvement in the Plant Production process. This chapter describes the state of the art regarding the Plant Production process, as well as the floor plan and layouts of equipment and culture beds of a PFAL, and also discusses sanitation.

Moving Toward Self-Learning Closed Plant Production Systems
LED Lighting for Urban Agriculture, 2016Co-Authors: Toyoki Kozai, Kazuhiro FujiwaraAbstract:A general scheme of next-generation closed Plant Production systems (CPPS) with self-learning ability (s-CPPS), consisting of virtual and real CPPS as the two main components, is presented. In virtual CPPS, various models to show the environmental effects on Plant growth and mass and energy balance in the CPPS are embeded and then used for predictive simulations of real CPPS. The values of coefficients (parameters) in the models are adjusted by a parameterization process to fit better with those in real CPPS. Once an s-CPPS is developed, it can be utilized, after some revisions, in open and semi-closed greenhouse crop Production systems. Recent global technologies are advantageous in s-CPPS. For example, information and communication technology (ICT); artificial intelligence (AI) with big data mining, deep learning, pattern recognition, etc.; the Internet of Things (IoT); and bioinformatics can be combined to make s-CPPS smarter. s-CPPS are integrated Plant Production systems for next-generation urban agriculture.

resource use efficiency of closed Plant Production system with artificial light concept estimation and application to Plant factory
Proceedings of the Japan Academy. Series B Physical and biological sciences, 2013Co-Authors: Toyoki KozaiAbstract:Extensive research has recently been conducted on Plant factory with artificial light, which is one type of closed Plant Production system (CPPS) consisting of a thermally insulated and airtight structure, a multi-tier system with lighting devices, air conditioners and fans, a CO2 supply unit, a nutrient solution supply unit, and an environment control unit. One of the research outcomes is the concept of resource use efficiency (RUE) of CPPS. This paper reviews the characteristics of the CPPS compared with those of the greenhouse, mainly from the viewpoint of RUE, which is defined as the ratio of the amount of the resource fixed or held in Plants to the amount of the resource supplied to the CPPS. It is shown that the use efficiencies of water, CO2 and light energy are considerably higher in the CPPS than those in the greenhouse. On the other hand, there is much more room for improving the light and electric energy use efficiencies of CPPS. Challenging issues for CPPS and RUE are also discussed.

Terrestrial Plant Production and climate change
Journal of Experimental Botany, 2010Co-Authors: Andrew D. FriendAbstract:The likely future increase in atmospheric CO(2) and associated changes in climate will affect global patterns of Plant Production. Models integrate understanding of the influence of the environment on Plant physiological processes and so enable estimates of future changes to be made. Moreover, they allow us to assess the consequences of different assumptions for predictions and so stimulate further research. This paper is a review of the sensitivities of one such model, Hybrid6.5, a detailed mechanistic model of terrestrial primary Production. This model is typical of its type, and the sensitivities of the global distribution of predicted Production to model assumptions and possible future CO(2) levels and climate are assessed. Sensitivity tests show that leaf phenology has large effects on mean C(3) crop and needleleaved cold deciduous tree Production, reducing potential net primary Production (NPP) from that obtained using constant maximum annual leaf area index by 32.9% and 41.6%, respectively. Generalized Plant Type (GPT) specific parameterizations, particularly photosynthetic capacity per unit leaf N, affect mean predicted NPP of higher C(3) Plants by -22.3% to 27.9%, depending on the GPT, compared to NPP predictions obtained using mean parameter values. An increase in atmospheric CO(2) concentrations from current values to 720 ppm by the end of this century, with associated effects on climate from a typical climate model, is predicted to increase global NPP by 37.3%. Mean increases range from 43.9-52.9% across different C(3) GPTs, whereas the mean NPP of C(4) grass and crop increases by 5.9%. Significant uncertainties concern the extent to which acclimative processes may reduce any potential future increase in primary Production and the degree to which any gains are transferred to durable, and especially edible, biomass. Experimentalists and modellers need to work closely together to reduce these uncertainties. A number of research priorities are suggested. 'The green leaf or, to be more precise, the microscopic green grain of chlorophyll, is the focus, the point in the world to which solar energy flows on one side while all the manifestations of life on earth take their source on the other side.'

The floratech dilemma: A case study for potted Plant Production specialists
Horttechnology, 2001Co-Authors: Neil O. AndersonAbstract:This paper presents a case study for use as an active learning tool with students in a floriculture potted Plant Production class. Students work together in small groups (three to four) to pose answers to a dilemma. With this case study, students quickly learn the names of their colleagues and work together outside-of-class to solve the assignment. Each student role-plays being hired on as a new potted Plant Production specialist. A memorandum from the Board of Directors is delivered on their first day of work at Floratech, a company specializing in potted Plants. Floratech is a finisher company, purchasing plugs (vegetative or seed-propagated crops) from plug producers and rooting stations, and selling their final products to both wholesale and retail markets. Objectives of this case study are to determine 1) the students' fluency in terminology for potted Plant Production, 2) ideal Production time/labor inputs for the Floratech potted crops, and 3) limiting factor(s) preventing each crop from reaching this goal. As the students progress through the course material, they refer to the memorandum for clarification of unknown terms. Unresolved questions are raised during the semester (in the classroom and during laboratory tours) to other players interacting in the memorandum, i.e., Floratech staff (growers, sales people, management), its suppliers (rooting stations, plug producers, distributors, breeders, producers, operations, quality control), and customers (wholesale, retail). This case study was tested with undergraduate students enrolled in HORT 4051, Floriculture Production and Management I (Potted Plants) at the University of Minnesota, St. Paul, during Fall Semester 1999.

Cultivar Trial Setup: A Case Study for Potted Plant Production Specialists
Horttechnology, 2001Co-Authors: Neil O. AndersonAbstract:A case study is presented for use as an active learning tool for students in a floriculture potted Plant Production class. This is the second case study developed for Floratech, a potted Plant finisher. Students work together in small groups to solve the proposed problems; each student role-plays as a Potted Plant Production Specialist. A memorandum from the Board of Directors is delivered in their first month on the job at Floratech. Objectives of this case study are to determine the students' fluency in terminology and crop-specific cultural requirements for potted Plant Production of cyclamen (Cyclamen persicum) and primrose (Primula sp.) as well as their ability to setup a scientifically rigorous and unbiased cultivar trial for Floratech personnel and selected customers. Students research the latest commercial catalogs to determine which species, series, and cultivars are available, as well as their relative merits, prior to choosing the appropriate cultivars to include in the trial. The trial setup has a space limitation of 2,000 ft2 (186 m2). This case study was tested with 20 undergraduate students during Fall Semester 1999. The case study demonstrated the students' fluency with terminology and crop-specific cultural requirements for both crops. Their ability to set up a scientifically rigorous trial varied widely, often with an inadequate sampling of cultivars and excessive replications (56 ± 37 cyclamen to 132 ± 65 primrose). A mean ± sd of 4 ± 1 cyclamen and 7 ± 3 primrose series were chosen. The number of cultivars varied from 6 ± 2 cyclamen to 9 ± 4 primrose and the number of distributors was similar for the crops. Trial design and additional questions raised by the case study were discussed in class and applied in a cultivar trial in the lab. Unanswered questions were used as learning opportunities during class tours with local growers.
