Eight-Point Charter of Agriculture (1958)
In the 1950s, the Chinese government proposed various methods to improve agricultural production. According to the official decision of January 1956, twelve measures needed to be taken to increase production. These consisted of: building up irrigation; increasing the application of fertilizer; improving old-style tools and developing new tools; promoting superior seed strains; expanding multiple-cropping areas; producing more high-yield crops; practicing intensive cultivation and improving farming methods; improving soil; conserving water and soil; protecting and propagating farm animals; eliminating pests and plant diseases; reclaiming wasteland and increasing the farming area.
According to Mao Zedong, these measures could be condensed in eight words: tu, fei, shui, zhong, mi, bao, guan, gong (soil improvement, fertilizer application, water conservancy, seed-strain improvement, close planting, plant protection, field management and tool reform). As a result, the Eight-Point Charter of Agriculture (ba zi xianfa, 八字宪法) was drawn up in 1958. Judging by the poster above, published in 1974, the measures were still considered relevant in the 1970s.
