概括
将远红光 (FR) 添加到温室照明中可以提高番茄产量,达到0.40FR的微小部分. 除此之外,产量增加减少,效率下降,对水果质量的影响最小.
科学领域:
- 园艺科学 园艺科学
- 植物生理学 植物生理学
- 农业工程 农业工程
背景情况:
- 温室照明通常缺乏足够的远红光 (FR),影响作物产量.
- 之前的研究表明,FR可提高低分量的产量,但最佳水平尚不清楚.
研究的目的:
- 量化番茄果实产量与补充照明中的FR分数之间的关系.
- 研究FR对产量和水果质量的影响的生理驱动因素.
主要方法:
- 两种番茄品种在不同的FR分数 (0.22-0.49) 下长了20周.
- 恒定的光合作用光子流量密度 (250 μmol m-2 s-1) 和光周期 (16h).
- 收益组件分析,水果质量和保质期评估.
主要成果:
- 番茄果实产量线性增加,达到0.40的FR分数 (+16%的产量).
- 与较高的植物干重和水果干物分离相关的产量增加.
- 辐射和电力使用效率在FR分数0.44和0.49下降.
结论:
- 额外的FR光线有效地增加了番茄产量,达到0.40.的FR分数.
- 较高的FR分数产生较低的回报,并降低照明效率.
- FR对番茄果的质量和保质期的影响最小.

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...
