Abstract

The work is devoted to the study of the photosynthetically active radiation spectral characteristics influence on the productivity and quality of lettuce and dwarf tomato adapted for protected ground. High pressure sodium lamps and LEDs emitting yellow light, pink light and close to sunlight spectrum were used as test options for plant illumination. Vegetable crops were grown under controlled conditions of intensive lightculture by thin-layer panoponics; the same irradiance was achieved in all variants. Using a light source simulating sunlight with a photosynthetic photon flux of 76 μmol m^–2 s^–1 in the 400–500 nm range, 130 μmol m^–2 s^–1 in 500–600 nm and 133 μmol m^–2 s^–1 at 600–700 nm made it possible to obtain an increase in productivity by 10% for lettuce and by 23% for tomato, and also led to an increase in the content of magnesium and iron in lettuce leaves and a higher content of carbohydrates, vitamin C, crude ash in tomato fruits compared to standard sodium lamps.

光照光谱对果树和叶菜类作物产量和生化成分的影响

摘要这项工作致力于研究光合有效辐射光谱特性对保护地生菜和矮番茄产量和质量的影响。高压钠灯和发光二极管发出的黄光、粉红光和接近太阳光的光谱被用作植物照明的试验选项。蔬菜作物是在受控条件下，通过薄层泛光照明技术进行集约化光照栽培的；所有变体都实现了相同的辐照度。使用模拟太阳光的光源，其光合光子通量在 400-500 纳米范围内为 76 μmol m-2 s-1，在 500-600 纳米范围内为 130 μmol m-2 s-1，在 600-700 纳米范围内为 133 μmol m-2 s-1、与标准钠灯相比，莴苣叶片中的镁和铁含量增加，番茄果实中的碳水化合物、维生素 C 和粗灰分含量增加。

期刊介绍： Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
