Kale refers to kale, also known as white kale and green leaf cabbage. Every 100 grams of fresh kale sprouts contains about 91% water, 0.74 to 1.00 grams of reducing sugar, and 1.60 to 2.08 grams of protein. , β-carotene 0.96 to 2.0 mg;

Vitamin C 80.7 to 101 mg, potassium 295 to 390 mg, sodium 43.7 mg, calcium 199 mg, magnesium 32.7 mg, phosphorus 54.6 mg, copper 0.05 mg , iron 1.31 mg.

Kaline contains organic alkali, which gives it a certain bitter taste, can stimulate people's taste nerves, increase appetite, speed up gastrointestinal motility, and help digestion.

Extended information:

Kale prefers a moist soil environment, and the maximum soil water holding capacity is 80% to 90%. It is intolerant to drought and has slightly better waterlogging tolerance than other cabbage vegetables. However, excessive soil moisture or stagnant water in the field will affect root growth.

Kale likes a mild climate and has strong heat resistance. Its ability to withstand high temperatures is the strongest among cabbage vegetables. The suitable temperature for seed germination and seedling growth is 25-30°C. Growth is slow below 20°C. The suitable temperature for leaf cluster growth and vegetable moss formation is 15-25°C. It likes a large temperature difference between day and night.

High temperatures above 30°C are unfavorable to the development of vegetable moss, and growth is slow below 15°C. Varieties with different ripeness have different temperature requirements for heat resistance and flower bud differentiation.

Early to mid-maturing varieties are more heat-resistant, and flower buds can differentiate quickly at higher temperatures of 27 to 28°C. Lowering the temperature has no obvious promotion effect on flower bud differentiation.
