Excessive application of nitrogen fertilizer will lead to the growth of baby cabbage with black spots, which will not affect eating. However, if there is a large area of black spots and rot in the baby cabbage, it means that the baby cabbage is infected with black rot. This kind of baby cabbage has been infected with bacteria and is no longer suitable for eating, which is likely to pose a threat to the liver after eating. Don't store the baby cabbage for too long after you buy it. It is better to use it as soon as possible.
Matters needing attention in doll dish selection
1, choose authentic doll dishes, you should choose small size, uniform size, and firm feel. If it is pinched loosely, it may be faked with a Chinese cabbage core. Because the doll dish is more popular with people, therefore, the merchants will pass it off as inferior, and pretend it is the heart of Chinese cabbage, because the price of doll dish is much higher than that of Chinese cabbage.
2. The leaves of the baby cabbage are light yellow. Because of different varieties, if it is a cabbage heart, it will be white in yellow. Even if many greenhouses prevent Chinese cabbage from seeing the light to make fakes, the color of the leaves of Chinese cabbage is different from the natural color of the baby cabbage.
3. Baby cabbage has a narrow leaf base and delicate veins, while Chinese cabbage has a wide leaf base and veins.
4. The core of Chinese cabbage grows closely, and its leaves are severely shriveled and twisted. The leaves of the doll dish are relatively flat, and the curly patterns of the leaves are also exquisite and small and beautiful. Doll leaves are straight, and cabbage leaves bend inward.
