Accurate measurements and control of light environment can significantly affect plant growth; thus, light measurement and control techniques are important for increasing plant yield. The lowest-cost option amounts to measuring the illuminance, for which instruments are readily available; more advanced techniques address measurements of radiation and photon fluxes. For the evaluation of photosynthesis under various light sources, the most informative quantity is the flux of photosynthetic photons in the 400―700 nm range of wavelengths (Tibbitts et al., 1983). To comprehensively evaluate the light environment including photomorphogenesis, spectroscopic measurements and analysis are becoming indispensable. Many spectrometers have been introduced into plant research laboratories, leading to some significant advances (Kendrick and Kronenberg, 1986). However, because spectrometers are much more expensive than illuminance meters, this approach is not practical for use in small-scale fields, such as the ones that are cultivated by many farmers in Japan. Consequently, these relatively expensive devices remain unpopular. The development of the micro electro mechanical systems (MEMS) technology has contributed to miniaturization and cost reduction of sensors (Kaajakari, 2009). Some micro-spectrometer MEMS devices that combine reflective concave brazed gratings and complementary metaloxide-semiconductor (CMOS) linear image sensors have been commercialized (Hamamatsu Photonics, 2017). To fabricate a measuring instrument that uses the MEMS technology, a computer system for controlling and a case for housing are required. Up to date, it has been difficult to solve these problems in research laboratories, and the existing prototypes have been bulky and costly. Recently, digital fabrication technology has been proposed for overcoming these technical problems in a small lot production (Walter-Herrmann and Büching, 2014). Based on the increasing use of open source hardware (computers) and three-dimensional (3D) printers, a framework for developing and manufacturing equipment for digital gadgets, called FabLab, was established (Pearce, 2012). Owing to this technology, fabrication of prototypes has become much less expensive. A low-cost spectrometer, featuring an MEMS device and open source hardware, was designed and manufactured using a 3D printer. Four manufactured spectrometers were installed inside and outside of a tomato canopy in an experimental greenhouse, and were tested to determine their usability for continuous measurements and spectroscopic
光环境的准确测量和控制对植物生长有重要影响;因此,光测控技术对提高植物产量具有重要意义。成本最低的选择是测量照度,这方面的仪器是现成的;更先进的技术涉及辐射和光子通量的测量。对于各种光源下光合作用的评价,最具信息量的是400-700 nm波长范围内的光合光子通量(Tibbitts et al., 1983)。为了全面评价包括光形态发生在内的光环境,光谱测量和分析变得必不可少。许多光谱仪已被引入植物研究实验室,导致一些重大进展(Kendrick和Kronenberg, 1986)。然而,由于光谱仪比照度计贵得多,这种方法不适用于小规模的田地,比如日本许多农民耕种的田地。因此,这些相对昂贵的设备仍然不受欢迎。微机电系统(MEMS)技术的发展促进了传感器的小型化和成本降低(Kaajakari, 2009)。一些结合反射凹面钎焊光栅和互补金属氧化物半导体(CMOS)线性图像传感器的微型光谱仪MEMS器件已经商业化(Hamamatsu Photonics, 2017)。为了制造一个使用MEMS技术的测量仪器,需要一个计算机控制系统和一个外壳。到目前为止,这些问题很难在研究实验室中解决,而且现有的原型机体积庞大,成本高昂。最近,为了克服小批量生产中的这些技术问题,已经提出了数字制造技术(Walter-Herrmann and b ching, 2014)。基于越来越多地使用开源硬件(计算机)和三维(3D)打印机,建立了一个用于开发和制造数字设备的框架,称为FabLab (Pearce, 2012)。由于这项技术,制造原型的成本大大降低。采用MEMS器件和开源硬件的低成本光谱仪使用3D打印机设计和制造。在实验温室的番茄树冠内外安装了四个自制光谱仪,并对其进行了测试,以确定其连续测量和光谱的可用性

Profit Models Based on the Growth Dynamics of Lettuce Populations in a Plant Factory 基于植物工厂莴苣群体生长动态的盈利模型
Pub Date : 2018-10-01 DOI: 10.2525/ECB.56.143

Crop production is increasingly threatened by unusual weather, water shortages, and insufficient available land. In order to feed the world, protect the environment, improve health, and achieve economic growth, a new form of agricultural cultivation is required; indoor vertical farming, namely a plant factory system with artificial lighting, is expected to provide efficient production of food crops (Kozai et al., 2015). However, production in plant factories incurs several costs. Kozai (2007) and Ohyama (2015) previously studied the production costs; as the size of the plant factory increases, fixed costs increase, for example, large-scale air conditioning systems, automatic control systems for nutrient solutions (Son and Takakura, 1987; Ko et al., 2013) and high-throughput seedling diagnosis system (Moriyuki and Fukuda, 2016). Moreover, individual differences in plant growth (growth distribution) are also directly linked to profits. Therefore, a profit model is required to consider fixed costs, running costs, and growth distribution information in plant factories. In the profit model for plant factory, we should focus on shipping type and growth distribution at each growth stage (nursing stage and cultivating stage). The shipping type usually depends on a shipping threshold based on fresh weight of harvested plant. Plants over this threshold are able to be sold at a standard (good) price, one by one (yen plant ). On the other hand, plants less than this threshold are sold at a lower price, by unit of fresh weight (yen g ). Therefore, profit depends on the distribution of plant size at harvest, particularly on the ratio of standard plants that are over the shipping threshold. Moreover, because profit often fluctuates with growth fluctuations, the profit model also requires detailed information of growth dynamics (distribution of plant size and its time variation). However, growth dynamics in plant factory and their influence on profit as a function of shipping threshold have not been widely studied. Variables in the profit model included number of cultivation days, shipping threshold, cost-related parameters such as fixed costs and running costs, and growth-related parameters. Furthermore, parameters in the profit model depend on the plant factory. Therefore, total optimization for all parameters requires time and expense (Shuku and Nishimura, 2015); thus, it is also important to analyze the sensitivity of each parameter for profit and to identify the priority of these parameters. In this study, we investigated the growth dynamics of lettuce populations cultivated in a large scale commercial plant factory and established a profit model with various shipping types. In addition, the sensitivity analysis of this profit model was performed for each parameter, and significant parameters for profit were clarified.
农作物生产日益受到异常天气、水资源短缺和可用土地不足的威胁。为了养活世界、保护环境、增进健康和实现经济增长,需要一种新的农业种植形式;室内垂直农业,即人工照明的植物工厂系统,有望提供高效的粮食作物生产(Kozai等人,2015)。然而,在植物工厂生产会产生一些成本。Kozai(2007)和Ohyama(2015)此前对生产成本进行了研究;随着工厂规模的增加,固定成本增加,例如,大型空调系统,营养液的自动控制系统(Son和Takakura, 1987;Ko et al., 2013)和高通量幼苗诊断系统(Moriyuki and Fukuda, 2016)。此外,植物生长的个体差异(生长分布)也与利润直接相关。因此,需要一个考虑固定成本、运行成本和植物工厂增长分布信息的盈利模型。在植物工厂的盈利模式中,我们应该关注每个生长阶段(护理阶段和培育阶段)的运输类型和生长分布。运输类型通常取决于基于收获植物的新鲜重量的运输阈值。超过这个阈值的植物能够以标准(好的)价格一个接一个地出售(日元植物)。另一方面,低于这个门槛的植物按单位鲜重(日元)以较低的价格出售。因此,利润取决于收获时植物大小的分布,特别是超过运输门槛的标准植物的比例。此外,由于利润经常随生长波动而波动,因此利润模型还需要详细的生长动态信息(植物大小的分布及其时间变化)。然而,植物工厂的生长动态及其作为运输阈值函数对利润的影响尚未得到广泛的研究。盈利模型中的变量包括种植天数、运输门槛、固定成本和运营成本等成本相关参数,以及与增长相关的参数。此外,盈利模型中的参数取决于植物工厂。因此,对所有参数进行总体优化需要时间和费用(Shuku and Nishimura, 2015);因此,分析每个参数对利润的敏感性并确定这些参数的优先级也很重要。在本研究中,我们调查了大型商业植物工厂种植的生菜群体的生长动态,并建立了不同运输方式的盈利模型。此外,对该盈利模型的各个参数进行了敏感性分析,明确了盈利的重要参数。

Mango is a widely cultivated tropical fruit crop and exhibits climacteric behavior characterized by changes in respiration and ethylene production during development and ripening. Optimal postharvest ripening depends on many factors, but during shipping to distant high-value markets, ripening generally should be minimized. Monitoring the physiological activity presents possibilities for real-time response and the integration of smart technologies. However, systems are still needed which are portable, economical, and accurate. Optical sensors are low-cost but lack good accuracy, while electrochemical sensors are highly accurate but expensive. Economic nanoparticle sensors are being developed for potential applications in fruit quality monitoring, but they can be complex. This work explores possibilities for development of a monitoring system for climacteric fruits such as mango and presents results on testing of commercially available systems and development of sensors that will fit the criteria.
芒果是一种广泛种植的热带水果作物,在发育和成熟过程中表现出呼吸和乙烯生产变化的更年期行为。最佳采后成熟取决于许多因素,但在运往遥远的高价值市场期间,通常应尽量减少成熟。监测生理活动提供了实时响应和智能技术集成的可能性。然而,仍然需要便携、经济和准确的系统。光学传感器成本低但精度差,而电化学传感器精度高但价格昂贵。经济型纳米颗粒传感器正被开发用于水果质量监测的潜在应用,但它们可能很复杂。这项工作探索了开发芒果等更年期水果监测系统的可能性,并介绍了商用系统的测试结果和符合标准的传感器的开发结果。
