在种植时要注意选用新种子。下面介绍几种新旧蔬菜种子的特征。白菜、萝卜、芥菜等十字科蔬菜新种子,表面光滑,有光泽,有清香味,用指甲压开后成片状,有油分溢出,子叶浅黄色或黄绿色。旧种子,表皮发暗无光泽,常有一层“白霜”,有油脂味,用指甲压易碎而皮易脱落,油脂少,子叶黄色或深黄色。

In planting should pay attention to the selection of new seeds. Here are some characteristics of old and new vegetable seeds. Cabbage, radish, mustard and other cruciferous vegetables, new seeds, smooth surface, shiny, fragrant flavor, pressed into a sheet with a nail, oil overflow, cotyledons light yellow or yellow-green. The old seed, the epidermis dark dull, often a layer of “hoar frost,” a greasy taste, with brittle nails pressure and easy to fall off the skin, less fat, cotyledons yellow or dark yellow.
