日本滨松光电子公司成功地利用高功率半导体激光器进行了水稻栽培试验。我们把利用环境技术的植物周年生产(一年中生产)系统叫做植物工场。该项试验照明、温度、湿度等均采用人工控制。除去设备投资,人工照明所需要的电力占植物生产成本的大部分,所以,如何开发 Hamamatsu Photonics, Japan, successfully used high power semiconductor lasers for rice cultivation experiments. We refer to the annual plant production (one-year production) system that uses environmental technology as the plant site. The test lighting, temperature, humidity, etc. are manually controlled. Excluding equipment investments, artificial lighting requires much of the cost of plant production, so how to develop
