Kale was originally an ornamental plant in China, but a few years ago, countries in Europe and the United States found that Kale has very high nutritional value, so now it has become a food on our table. Many people who lose weight must be very familiar with kale powder. Kale powder is a powder made from kale and can generally be brewed and consumed.
Because Kale powder contains rich dietary fiber, it is favored by people who lose weight and fat. Dietary fiber can help maintain the normal function of the intestinal tract, promote intestinal peristalsis, help eliminate garbage toxins, and thus play a role in weight loss. Kale powder is also very awesome in promoting the elimination of waste toxins, which is very suitable for modern people to lose weight.
At present, sowing propagation is the main propagation method of Kale, but with the rapid development of hydroponic technology, hydroponic Kale is gradually reused. The hydroponic tower system is the best choice for domestic indoor hydroponic Kale. Kale prefers cold and cool climate, and the suitable temperature for growth and development is 20-25 ℃. However, it has strong cold and freezing resistance, as well as strong heat resistance. It can grow normally even at high temperatures in summer. It is a vegetable with strong stress resistance, a wide range of adaptability, and is relatively easy to hydroponic.
The rotating hydroponic tower system is a tower system that can rotate 360 ° under the action of electricity. The advantage of this tower system is that it can allow crops to receive light in all directions, promoting more uniform crop growth. The growth rate of hydroponic Kale planted on the hydroponic tower system was significantly accelerated. It only took about 60 days from sowing to harvesting, which could shorten half the time compared with the soil culture method.
Key points of indoor hydroponic Kale cultivation:
1. Seedling raising: sow Kale seeds that absorb enough water into the cross section of sponge blocks, and sow 2 seeds in each block. Then add enough water to the rice tray so that the water can reach the surface of the sponge block. Under normal circumstances, seedlings can emerge in 2-3 days.
2. Light: Kale needs about 6 to 10 hours of light every day. The LED Grow light equipped on the tower system can meet the light needs of Kale.
3. Kale plants grow well in the hydroponic system and need to be harvested irregularly.
Hydroponic Kale is a kind of precious lettuce and a high-quality vegetable used in lactobacillus milk and lactobacillus milk drinks. Due to the rich vitamins, trace elements and antioxidant substances, hydroponic Kale is delicious and nutritious, enjoying a high reputation in edible vegetables.
