Example Embodiment

[0024] Example 1

[0025] A method for indoor planting of red leaf lettuce using a combination of different LED light sources includes the following steps:

[0026] (1) Preparation of seedlings:

[0027] Accelerate the germination of lettuce seeds at 18~23℃. After the seeds break their buds and become white, sown them in seedling trays or sponge squares, in a hydroponic nutrient solution with a nutrient solution EC value of 1.2-2.4ms / cm and a pH value of 5.5-7.0 Hydroponic culture to 2 to 8 true leaves.

[0028] (2) Transplanting and planting and nutrient solution management:

[0029] Prepare the nutrient solution before transplanting, move the seedlings to the planting cup, fix the planting cup on the planting plate, and put it in the planting trough of the multi-layer three-dimensional planting rack. 7 days after transplanting, the EC value of the nutrient solution should be controlled at 1.2~2.0ms / cm and the pH value should be controlled at 5.5~7.0; after 7 days, the EC value of th...

Example Embodiment

[0036] Example 2

[0037] On the basis of Example 1, in this example, after the seedlings are transplanted, through the computer control system, turn on the white: red combination of 9:1 LED light source, keep the LED blue light source off, and use 9 hours of light per day with light intensity Keep it between 5000 and 20000lx, cultivate for 35-40 days.

[0038] Before harvesting, through the computer control system, turn on the blue: red combination of 5:1 LED light source, and turn off the LED white light source, maintain 9-16 hours of light every day, continuous light for 3-6 days, promote leaf color change and leaf growth Thick, improve quality. In this embodiment, the lettuce grows fast, can be harvested within 40 to 45 days, and has high yield and good quality.

Example Embodiment

[0039] Example 3

[0040] On the basis of Example 1, in this example, after the seedlings are transplanted, through the computer control system, turn on the white: red combination of 5:1 LED light source, keep the LED blue light source off, and keep the light intensity for 9 hours a day. Between 5000 and 20000lx, cultivate 35-40 days.

[0041] Before harvesting, through the computer control system, turn on the LED light source with the combination of blue: red and 3:1, and turn off the white LED light source. Keep the light for 9-16 hours a day, and continuously light for 3-6 days to promote leaf color change and leaf growth. Thick, improve quality. In this embodiment, it can be harvested within 40 to 45 days, with high yield and good quality.

Abstract

The invention provides a method for conducting indoor lettuce planting through different LED light source combinations. The method includes the following steps that lettuce seeds are germinated, seedling culture is conducted, and culturing is conducted till seedlings with 2-8 main leaves emerge are obtained; the seedlings are transplanted and subjected to field planting; after transplanting is conducted, illumination treatment is conducted on the seedlings, LED light sources with the white and red ratio being 1:1-9:1 are adopted, illumination is conducted for 9-16 hours each day, and culturing is conducted for 20-40 days; LED light sources with the blue and red ratio being 1:0-5:1 are adopted, illumination is conducted for 9-16 hours each day, culturing is conducted for 3-10 days, and then harvesting is conducted. By the adoption of the technical scheme, purple or red lettuce can be cultured rapidly, the yield is high, quality is good, and high production practicability is achieved.

Description

technical field [0001] The invention belongs to the technical field of vegetable cultivation, and in particular relates to a method for indoor planting of lettuce by using combinations of different LED light sources. Background technique [0002] With the continuous improvement of people's living standards, the importance of vegetables is getting higher and higher, and purple or red lettuce varieties are constantly entering people's lives. This kind of special vegetables used to be directly imported from abroad and reused. New varieties bred by advanced breeding techniques. In addition to the good-looking color, this special vegetable mostly contains special nutrition and unique flavor, and some have certain health care and disease prevention functions. For example, purple leaf lettuce contains anthocyanins, carotene, vitamin E, etc., and is also rich in minerals, such as phosphorus, calcium, potassium, magnesium, etc., and a small amount of copper, iron, zinc, and selenium...
