《太平广记·卷四百一十一·草木六》
诸葛亮命令兵士在驻地专种蔓菁的原因，取它刚长出来的嫩甲可以生吃，这是其一；叶子长大之后，可以煮着吃，这是其二；如果在此久住，它就继续生长，这是其三；扔掉也不让人感到可惜，这是其四；回来的时候容易找到，继续食用，这是其五；冬天可以食用它的根，这是其六。
诸葛所止，令兵士独种蔓菁者，取其才出甲可生啖，一也；叶舒可煮食，二也；久居则随以滋长，三也；弃不令惜，四也；回则易寻而采之。五也。冬有根可斸食，六也。
The reason why Zhuge Liang ordered the soldiers to grow turnips in the garrison area was: First, the tender leaves that grew out could be eaten raw; second, the leaves could be cooked and eaten after they grew larger; third, the turnips could continue to grow if they stayed there for a long time; fourth, they would not be a waste to throw away; fifth, they were easy to find and eat when they returned; and sixth, the roots could be eaten in winter.
