Extended data:

Peanut and other crops in different areas of China form a planting system of one crop a year, three crops a year, two crops a year or three crops a year, which can be divided into spring peanuts, wheat peanuts, summer peanuts and autumn peanuts, and winter peanuts can also be planted in some areas of Guangdong.

Part of peanut planting has been developed to paddy fields, forming peanut-rice or rice-peanut rotation system. In some places, the growing season is longer, the rice variety is suitable, and it can also be rotated with double cropping rice.

The autumn peanut pods planted in Guangdong and Fujian are reserved for the second spring sowing, which can improve the emergence rate and ensure the whole seedling in Miao Zhuang, commonly known as "turning over the autumn seeds" or "spring sowing"
