Abstract: In traditional peanut planting, two or more seeds were planted in one hole. Seedlings in the same
hole competed for fertilizer, water resources, light and heat resources, which led to the different growth of seedlings
and limited increase of pod yield. The peanut cultivation and physiological ecology innovation team of Shandong
Academy of Agricultural Science has established peanut single seed sowing technology. It sowed one seed in a hole
instead of two or more, and expanded plant spacing, alleviated the competition between adjacent plants, and made
the individual uniform, orderly and robust, which could give full play to the potential of single plant production. The
number of plants per unit area decreased, which made the group structure more reasonable, and increased the distri⁃
bution rate of photosynthetic products to pods, thus increased production by increasing economic coefficient. This
paper discussed the development process, breakthrough of the theory, technology and development prospect of pea⁃
nut single seed sowing technology, and brought forward the technical bottleneck to limit large-scale promotion, in
order to speed up the application of this technology.

Key words: peanut, single seed sowing, development process, theory and technology, prospect
