Embodiment 1

[0065] Example 1: Cutting under LED light regulation

[0066] (1) Sowing the seeds of the green onions in the acupoints equipped with a seedling matrix, use 72-hole plate matrix to seed the seedlings, the seedling matrix is ​​composed of plant, pearl rock and vermiculite, composed of 6: 3: 1; Sowing 4 seeds, broadcast 0.5cm, after the broadcast is compacted, and after the water is covered with water, the film is removed in time to the seed germination. After the green onion seeds, the conditions of seedling and seedling are: watering a nutrient solution every 3d, and retains 2-3 plants per hole through the seedlings, and the light intensity is 220μmol · m. -2 · S -1 The illumination time is 14h / d, the temperature is 24 ° C, the relative humidity is 65-70%, and the seedling of the seedling is about 15 cm, and has a seedling of 2-3 leaf leaves.

[0067] (2) Put the seedlings of step (1) into the cultivation frame of the plant factory to cultivate, the cultivation matrix placed on ...

Abstract

The invention discloses a green onion cultivation method under LED light regulation, which comprises the following steps: (1) after germinating the green onion seeds, the seedlings are raised until the seedlings with 2-3 true leaves are cultivated; (2) the step (1) ) and transplanted to the cultivation frame of the plant factory for cultivation, and irradiated with LED light group during the cultivation process, so that the light intensity of the plant canopy was maintained at (301.6±12.7) μmol m ‑2 ·s ‑1 , the illumination time is 12‑14h / d; the LED lighting group includes blue LEDs and white LEDs. The shallots cultivated by the method of the invention have high photosynthetic efficiency and excellent product quality, and the shallot leaf pigment, photosynthetic efficiency, stomatal conductance and light energy utilization rate are all significantly increased.

Description

Technical field [0001] The present invention relates to the field of crop cultivation techniques, and more particularly to a campling method under LED light regulation. Background technique [0002] In recent years, the plant factory of all artificial light sources has become a smart new equipment in the facility agriculture, especially facilities, vegetable production, which is the main principle to provide optimal illumination conditions for crop growth, with production environment. Highly controllable, continuous and stable production and product quality and reliability and so on. Light is both an energy source of photothermation, and is also an important source, light intensity, light quality, and optical cycle in the plant growth and development. Growth development. Studies have shown that blue light can improve the photosynthetic content of lettuce leaves compared to white light, which promotes the opening of cucumber leaves; and red light can improve the photosynthetin con...
