Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plant breeding, in particular to a light regulation method for promoting cherry tomato rapid propagation and generation. BACKGROUND

[0002] Cherry tomato (Lycopersicon esculentum var. cerasiforme A. Gray) is an annual or perennial vine herb of Solanaceae Lycopersicon cultivar, and the fruit is nearly round, and the fruit skin color is fire red, pink and the like. Cherry tomato is named as "cherry tomato" because of its similar shape to cherry.

[0003] Cherry tomato is small and exquisite, and the color is bright. Not only the taste is delicious, but also the nutritional value is high, and a large amount of antioxidants and vitamin C are contained, and a large amount of special substances such as glutathione and lycopene are contained. These substances can promote the growth and development of human body, especially can promote the growth and development of children, and can increase the resistance of human body and delay the aging of human body. Lycopene can protect human body from the invasion of carcinogenic toxins in cigarette smoke and automobile exhaust, and can improve the sunscreen function of human body. The content of vitamin PP in cherry tomato is the highest among fruits and vegetables, and the function of vitamin PP is to protect the skin, maintain the normal secretion of gastric juice, promote the generation of red blood cells, and has auxiliary treatment effect on liver disease. It is deeply loved by consumers.

[0004] Cherry tomato is a light-loving crop, and the sunshine duration is shorter in the autumn and winter seasons in the north and the rainy seasons in the south. Long-term low light will cause cherry tomato to grow poorly in the process of generation breeding.

[0036] In the cultivation process of the cherry tomato plants, the environmental temperature needs to be maintained at 12-30℃, and the air relative humidity needs to be maintained at 80%-90%. In addition, in the cultivation process of the cherry tomato plants, soil culture or nutrient solution culture can be selected, so that the application range is wider.
