The Book of Qi Yao Min emphasizes that planting vegetables in different border areas can make rational use of land and the output of vegetables is also high. It is convenient for watering and field work, and prevents people from stepping on vegetable fields. The size of a vegetable field is generally 2 meters long and 1 meter wide. The border of leek planting must be deep, because manure should be added to leek every harvest.

Vegetables generally have a short growth period and require a large amount of fertilizer, so base fertilizer must be applied to vegetable fields. The base fertilizer is generally manure, or mung beans are sown in front of vegetable fields, and then pressed green at an appropriate time as the base fertilizer. After sowing, manure is often applied, that is, half of the soil is mixed with decomposed manure after sowing, or rape is covered with cooked manure.
