可调控光环境下的植物表型采集系统设计
摘 要
光环境是影响植物生长发育和物质代谢的一个重要因素。不同的植物种类对红蓝光组合比、光照强度及光照时间的需求各不相同，在可调控光环境下进行植物表型研究可以实现光调控的精准化、智能化对指导植物生产具有重要意义，但目前林业育种研究领域缺乏有效的试验不同植物品种所需光照强度、光质和时间的表型采集与分析系统。光环境控制试验要花费大量的人力收集常规表型数据，手动测量过程繁琐、误差大、且易使外界光影响试验结果的问题。实时自动化的表型采集系统是精确林业育种领域的强烈需求，急需设计一台可调控光环境的植物表型采集系统来实现全自动、多种类、高通量、大样本测量的数据采集和表型分析，实现对大量植物品种进行省时省力的批量试验，测得不同品种植物生长最适宜的光环境。

Design of plant phenotype collection system under controllable light environment
ABSTRACT
Photoenvironment is an important factor affecting plant growth and material metabolism. The demands of different plant species on the combination ratio, light intensity and light time of red and blue are different. It is important to study plant phenotype under the controllable light environment to realize the precision and intelligence of light regulation and control, which is of great significance to guide plant production. However, there is no effective phenotypic test in the field of forestry breeding research on the intensity, quality and time of light required by different plant varieties Acquisition and analysis system. The light environment control test takes a lot of manpower to collect the conventional phenotype data, which is complicated and error is too complicated and easy to make the external light affect the test results. The real-time automatic phenotypic collection system is a strong demand in the field of precise forestry breeding. It is urgent to design a plant phenotype collection system which can regulate the light environment to realize the data collection and phenotype analysis of automatic, multi species, high-throughput and large sample measurement, and realize the time-saving and labor-saving batch test on a large number of plant varieties, and measure the most suitable optical ring for different species of plants The environment.

1、课题研究目的和意义
表型，又称表现型，是指生物体在给定的环境中，确定基因型表现出来的形态、结构、大小、颜色、成分与功能特征等物理、生理、生化性状，是基因型和环境共同作用的结果。早在DNA和分子标记被发现之前，人们就已经根据表型对品种进行选择、确定和改良，依靠肉眼观察进行表型评估，将田间小块作物的长势、倒伏和衰老等作为判断依据。植物表型信息采集技术是农业生产领域的重大革新，通过这项技术，可以快速获取植物的结构、形态、生长、光合作用等特征，客观准确地得到各项表型数据，对生物体进行从宏观到微观的系统展示，监测作物生长状况，从而为调控作物生长环境提供可靠依据，也为农作物优质丰产研究提供新的方法。
