Abstract

The invention discloses a lettuce cultivation system for promoting accumulation of antioxidant substances and a cultivation method thereof. The lettuce cultivation system comprises a solar energy power supply assembly, a lettuce cultivation assembly and a PLC automatic control system assembly, and the lettuce cultivation system can automatically adjust the lettuce growth environment according to the different growth characteristics of lettuces and all monitoring parameters. The invention further discloses the lettuce cultivation method using the above system. The formation of the antioxidant substances is promoted through the control over the quality of light needed by crop growth; the lettuces are promoted to start the genetic expression of an antioxidant system by preparing an organic matrix formula; the accumulation of the antioxidant substances in lettuce bodies is promoted by utilizing the optimal configuration of LED blue light and ultraviolet light; lettuce growth parameter conditions are set and intelligently regulated and controlled according to the different duration period growth characteristics and environmental responses of the lettuces, and the lettuce cultivation system promoting the accumulation of the antioxidant substances and the cultivation method thereof are very suitable for the cultivation of the lettuces with high-quality antioxidant substances.

Description

technical field [0001] The invention relates to a vegetable cultivation system and a cultivation method, in particular to a lettuce cultivation system and a cultivation method which promote the accumulation of antioxidant substances. Background technique [0002] Leaf lettuce, also known as lettuce, is an annual or biennial plant of Lactuca sativa L. in the family Asteraceae, and is one of the vegetables widely grown in the world. Because it is rich in many highly active antioxidant substances (such as polyphenolic compounds, ascorbic acid, carotenoids and vitamin E, etc.) and dietary fiber, it is also called "healthy food". Mini lettuce is a lettuce product with high added value. Compared with ordinary lettuce, mini lettuce is more concerned about the nutrients and taste, so the management of water, fertilizer and temperature during cultivation is more stringent. Modern greenhouses have the advantages of not being affected by the natural climate, automatic implementation,...
