蔬菜设施栽培中的光温调控技术研究
摘 要
蔬菜设施栽培中的光温调控技术是现代农业生产中的关键环节，尤其在气候变化和资源紧缺的背景下，如何通过科学调控提升蔬菜产量和品质成为亟待解决的问题。本研究旨在探讨不同光温条件下设施蔬菜的生长响应机制，并提出优化调控策略。研究选取了典型的设施蔬菜品种（如番茄、黄瓜）作为实验对象，采用多因子实验设计，结合人工光源和温度控制系统，模拟不同光强、光周期及温度组合下的生长环境。通过生理生化指标、产量和品质的综合分析，揭示了光温调控对蔬菜生长发育的影响规律。结果表明，适宜的光强和温度组合能够显著提高蔬菜的光合效率和养分利用率，进而提升产量和品质。特别是在冬季低温环境下，增加光照强度并辅以适当的温度调控，可有效缓解低温胁迫对蔬菜生长的负面影响。

STUDY ON LIGHT TEMPERATURE CONTROL TECHNOLOGY IN VEGETABLE FACILITY CULTURE
ABSTRACT
The light and temperature control technology in vegetable facility cultivation is a key link in modern agricultural production. Especially under the background of climate change and resource shortage, how to improve the yield and quality of vegetables through scientific regulation has become an urgent problem to be solved. The aim of this study was to investigate the growth response mechanism of facility vegetables under different light temperature conditions and propose optimized regulation strategies. In this study, typical facility vegetable varieties (such as tomato and cucumber) were selected as the experimental ob ject, using multi-factor experimental design, combined with artificial light source and temperature control system, to simulate the growth environment under different light intensity, photoperiod and temperature combinations. Through the comprehensive analysis of physiological and biochemical indexes, yield and quality, the influence of light temperature regulation on vegetable growth and development is revealed. The results show that the appropriate combination of light intensity and temperature can significantly improve the photosynthetic efficiency and nutrient utilization rate of vegetables, and then improve the yield and quality. Especially in cold winter environments, increasing the light intensity and supplemented by proper temperature regulation can effectively alleviate the negative effects of cold stress on vegetable growth.
