目的研制成空间蔬菜栽培装置地面实验样机,以便解决空间环境条件下栽培蔬菜的若干关键技术,为下一步研制空间蔬菜栽培装置样机和上天产品,并最终为在我国空间站实现空间蔬菜生产的实验与应用奠定基础。方法在详细技术方案论证与设计的基础上,进行了部件图纸设计与投厂加工、整机设备安装、调试、试运行和验证实验等。结果该样机栽培室内的温度、相对湿度、风速、总压、O2分压、CO2分压和栽培基质水分含量均实行自动而有效的控制;光源为高效电子荧光灯;平均蔬菜生产量可以 达到60g鲜重·d-1。结论该样机运行平稳,实际性能基本达到了预定的技术指标,部分组件的工作原理能够适应空间微重力环境,从而为今后研制空间蔬菜栽培装置打下了良好基础。
Objective To develop a ground-based laboratory prototype of a space vegetable cultivation device to solve some key techniques of vegetable cultivation under space environment conditions for the next step to develop a prototype of a space vegetable cultivation device and a product of the heaven, and finally to experiment and achieve spatial vegetable production in our space station Application laid the foundation. Methods Based on the demonstration and design of the detailed technical solutions, part drawing design and processing, component installation, commissioning, commissioning and verification experiments were carried out. Results The temperature, relative humidity, wind speed, total pressure, O2 partial pressure, CO2 partial pressure and moisture content in culture medium were all controlled automatically and effectively. The light source was high efficient electronic fluorescent lamp. The average vegetable production could reach 60g Heavy · d-1. Conclusions The prototype runs smoothly and the actual performance has basically reached the predetermined technical index. The working principle of some components can adapt to the space microgravity environment, which lays a good foundation for the future development of space vegetable cultivation device.
