Embodiment 1

[0021] A hydroponic method of selenium-enriched black tomato, comprising the following steps:

[0022] (1) Select plump black tomato seeds, soak and disinfect them in 0.5% sodium hypochlorite solution for 10 minutes, wrap them with gauze, wash them repeatedly with clean water for 3 times, and accelerate germination in a dark place at 25°C;

[0023] (2) Seeds after accelerating germination are sown into 50-hole hole trays filled with vermiculite to grow seedlings, 2 seeds are sown in every hole, about 0.5cm in depth, and watered irregularly before emergence;

[0024] (3) When the black tomato seedlings grow 5 to 6 true leaves, put the hole tray on a plastic plate with small holes, and put the plastic plate into nutrient solution A for planting and cultivating. The temperature during the day is controlled at 22 to 28 ℃, the temperature at night is controlled at 15-18 ℃, and the black tomato plants are placed in a sunny place, and the nutrient solution A and water are supplemente...

Embodiment 2

[0031] A hydroponic method of selenium-enriched black tomato, comprising the following steps:

[0032] (1) Select plump black tomato seeds, soak and disinfect them in 0.5% sodium hypochlorite solution for 15 minutes, wrap them with gauze, wash them repeatedly with clear water for 5 times, and accelerate germination in a dark place at 25°C;

[0033] (2) Seeds after germination are sown into a 72-hole hole tray filled with vermiculite to raise seedlings, 1 seed is sown in each hole, and the depth of sowing is about 0.5cm, and watering is irregular before emergence;

[0034] (3) When the black tomato seedlings grow 5 to 6 true leaves, put the hole tray on a plastic plate with small holes, and put the plastic plate into nutrient solution A for planting and cultivating. The temperature during the day is controlled at 22 to 28 ℃, the temperature at night is controlled at 15-18 ℃, and the black tomato plants are placed in a sunny place, and the nutrient solution A and water are suppl...

Abstract

The invention discloses a selenium-rich black tomato hydroponic method. According to the invention, through changing a sulfur fertilizer content in nutrient solutions for different growth stages during a black tomato hydroponic process, selenium absorption of the roots of black tomato is promoted. Through photosynthesis, black tomato converts inorganic selenium into organic selenium, such that a purpose of producing selenium-rich black tomato fruits is achieved.

Description

technical field [0001] The invention belongs to the field of crop planting, in particular to a hydroponic method for selenium-enriched black tomatoes. Background technique [0002] Black tomato, both medicine and food, is a treasure in the tomato family. It has a strong fruit flavor, high nutritional value, moderate sweet and sour, especially suitable for fresh food, and contains more lycopene, vitamin C and antioxidants than red tomatoes , easily absorbed by the body. The rich anthocyanins in black tomato can produce a strong biological effect in the human body and have a good anti-cancer effect. Regular consumption of black tomatoes has the effect of aphrodisiac for men, and can reduce the chance of men suffering from prostate cancer and heart disease; it can nourish yin and protect kidney, whiten skin, and lose weight for women. [0003] Selenium is one of the essential trace elements in the normal physiological process of the human body. Selenium in food is the main s...
