The seeds of spinach with sharp leaves have two sharp spines. This kind of spinach has a long planting history in China, and has strong cold tolerance, which is very suitable for root stubble overwintering or autumn planting. Spinach with sharp leaves is delicate, with narrow and thin leaves, like an arrow, and smooth leaves. Spinach with round leaves is also different from spinach with sharp leaves in taste. Many friends only like to eat leaves rather than stems when eating green vegetables. Spinach with pointed leaves has long stalks and small leaves, and contains more crude fiber, which makes it taste relatively poor. Although it is widely planted in greenhouses and developed in logistics, vegetables seem to be available at any time regardless of season, but the taste of varieties is still very different.

"Spinach with round leaves", the leaves are relatively large and thick, and there are many folds on it, and the color is dark green. "Sharp-leaf spinach" is just the opposite of "round-leaf spinach", with narrow, thin and thin leaves and basically no wrinkles. Whether it is round-leaf spinach or pointed-leaf spinach, they all contain a lot of oxalic acid. Before cooking, you must blanch and blanch the oxalic acid inside, so that it is healthier to eat. However, when blanching, it should be noted that their blanching time is different. Round-leaf spinach has less sugar content, but more cellulose content than pointed-leaf spinach, and there is a lot of oxalic acid, so this kind of spinach tastes a little bitter, and it is more resistant to cooking than pointed-leaf spinach.

Spinach with pointed leaves is usually planted in autumn and winter, with a long growth cycle and sunshine time. After nutrient absorption and sunlight exposure in the whole winter, it is naturally more nutritious than spinach with round leaves, especially the vitamin C content is higher than that of spinach with round leaves. Spinach is neither too big nor too small, and there is no bolting. The leaves are relatively intact, and there are no insect eyes or spots. Then gently pinch the spinach leaves with your hands. If it is slightly elastic and not rotten at the touch, the folic acid content of the round-leaf spinach will be more, and the other nutrients are basically the same, but folic acid itself is a rare nutrition, so it is also the advantage of round-leaf spinach.
