近年来日本又相继落成完全自动化的蔬菜工厂,并获得栽培成功,同时又开发出很多适应于蔬菜工厂的新技术。现介绍一下在近两年的实践中,最引人注目的几方面。一、育种首先进行色拉生菜的无性繁殖实验,也就是说,把色拉菜进行组织培养,一旦从变异中选出生长快的植株,即按程序反复培养。在这个预备试验中,仍然可以发现一些生育快的植株。但是在无性繁殖过程中,由于产生驯化问题,日立制作所基础研究开始转向完全自动控制的工厂化研究,这对营养液栽培和蔬菜工厂化育种很重要,因为广泛收集国外品种,在水培和工厂化环境条件下,通过杂交、改良,以几十倍的生长速度拿出新品种是很容易的事情。二、太阳光采光技术清水建设最近发明一种传送型低成本太阳采光装置,在输送太阳光的同时,利 In recent years, Japan has successively completed the establishment of a fully automated vegetable factory and succeeded in cultivation. At the same time, it has also developed many new technologies adapted to the vegetable factory. Here are some of the most striking aspects of practice in the last two years. First, the breeding First, the salad of lettuce asexual reproduction experiment, that is, the salad tissue culture, once selected from the mutation growing fast plants that repeatedly cultured according to the program. In this preliminary test, we can still find some fast-growing plants. However, in the process of asexual reproduction, due to domesticated problems, the basic research of Hitachi Institute turned to a fully automated industrialized study which is important for nutrient solution cultivation and vegetable factory breeding because of the extensive collection of foreign cultivars in hydroponics and Under industrialized environmental conditions, it is easy to take out new varieties at a rate of tens of times through hybridization and improvement. Second, the sun lighting technology Shimizu Construction recently invented a transmission-type low-cost solar lighting devices, in the transport of sunlight at the same time, Lee
