Morphological characteristics: 1. The root system of garlic is stringy and well-developed, with strong ability to absorb water and fertilizer. The leaves are long and narrow, and are dark green. The garlic bulb is a large corm, irregularly oblong in shape, with a light yellow outer skin.

Growth Habits 1. Garlic is a sun-loving crop that requires a significant amount of sunlight throughout its entire growth period. It exhibits a characteristic of first undergoing vegetative growth and then reproductive growth, necessitating ample fertilizer. Garlic has lower temperature requirements compared to rice and wheat. Its seedlings can tolerate temperatures ranging from -6°C to -8°C, while its stems and leaves can withstand temperatures from -3°C to -5°C. It grows well at temperatures above 2°C.

Nutritional Value 1. Garlic is rich in nutrients such as protein, oligosaccharides, polysaccharides, fat, and minerals. Its main active ingredient is allicin, which exhibits various physiological effects such as antioxidant, anti-inflammatory, and antibacterial activities. In addition, garlic contains abundant vitamins C and B6, selenium, and other nutrients beneficial to the human body.

Pharmacological Value1. Garlic possesses broad-spectrum antibacterial and antiseptic properties, as well as anti-inflammatory effects. It can enhance immune function, protect the cardiovascular system, and exhibit anti-tumor and anti-pathogenic microbial activities. Regular consumption of garlic can serve a preventive and healthcare role. The sulfur-containing organic compounds in garlic not only inhibit the synthesis of carcinogenic nitrosamines in the body but also have a direct cytotoxic effect on tumor cells. Furthermore, garlic can lower blood lipids, regulate blood sugar levels, and prevent thrombosis and arteriosclerosis.
