Background
Lettuce, a scientific name of leaf lettuce (Lactuca sativa l. var. ramosa Hort.), is a one-or two-year-old herb of the genus Lactuca of the family Compositae. The plant is short, the growing period is short (40-60 days), the yield is high, the nutrient content is high, the ornamental value is strong, and the plant becomes an important water culture vegetable. The lettuce is mainly eaten raw food, is mainly supplied to restaurants or supermarkets and is sold as salad. However, the monotonous color of the salad is always an unsatisfactory problem for consumers, and more varieties except green are gradually favored by consumers. The red lettuce is a mainstream variety in salad because of the beauty and the anthocyanin (with the functions of resisting cancer and resisting aging). However, at present, the purple or red lettuce variety has low cultivation yield, slow plant growth and high cost.
The prior art discloses a method for indoor lettuce planting by adopting different LED light source combinations, which generally comprises the following steps: germinating lettuce seeds, growing seedlings and culturing until 2-8 true leaves of seedlings are exposed; transplanting and field planting seedlings; after transplanting, carrying out illumination treatment on the seedlings by adopting a white light: the red combination is an LED light source with the ratio of 1: 1-9: 1, and the red combination is used for cultivating for 20-40 days after being illuminated for 9-16 hours every day; adopting blue: and combining the red with an LED light source with the ratio of 1: 0-5: 1, illuminating for 9-16 hours every day, culturing for 3-10 days, and then harvesting. The method can be used for quickly culturing purple or red lettuce, and has the advantages of high yield, good quality and strong production practicability.

Compared with the similar lettuce cultivation mode, under the integral environment and condition, the cultivation time is greatly shortened, the purposes of high cultivation yield and fast plant growth are achieved, the cultivated lettuce is high in quality, the cultivation mode is simple and reliable, the illumination treatment condition is relatively uniform, the number of light sources is small, the production cost is lower than that of illumination treatment under three or more light sources, and the control is simpler. Under the integral environment and conditions and the same harvest standard, the production period of the lettuce is shortened by 12-15%, and the average yield is improved by 19-25%.
Example 3:
this example 3 is the same as example 1 and/or example 2 except that: in the step d, the method also comprises the following steps: stopping the illumination for 0.3-0.5 hour every 1 hour of the illumination of the lettuce. The alternate illumination treatment mode is more favorable for stimulating the growth of the lettuce, thereby realizing the purpose of high yield.
The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
