吴簡《嘉禾吏民田家莂》中的旱田與熟田都是種植水稻的農田,但是前者農田形態不完善,缺乏穩定的灌溉水源。田家莂登錄的佃田主要是因無主而收歸官有的農田,這些旱田大都因配套的陂塘失修而失去灌溉水源,並非沒有灌溉的條件,要恢復成爲熟田並不特別困難。孫吴政權一方面設法將這些旱田租佃给吏民以免其完全荒蕪,一方面也加緊陂塘的修復以使其重新獲得灌溉水源。嘉禾五年與嘉禾四年相比,旱田與熟田的比例發生了明顯改觀。 The paddy fields and paddy fields in the Wujian “Jiahe Li Mintianjiawan” are both paddy fields, but the former farmland is imperfect and lacks a stable source of irrigation water. The tenant land to which Tian Jiabao was registered was mainly due to the absence of official farmland. Most of the dry land is not irrigated because of the incompatibility of the turtle ponds. It is not particularly difficult to restore the cultivated land to mature land. On the one hand, the Sun Wu regime managed to rent these dry fields to the people so that they would not be completely barren. On the one hand, it also stepped up the restoration of the pond to regain access to irrigation water. Jiahe five years compared with Jiahe four years, the proportion of dry land and cooked land has changed significantly.
