花生用种量大,繁殖系数低,一般大田产量只相当于播种量的十倍左右,所以过去一个新品种的推广和普及,需要十几年的时间,因此,花生良种的繁育推广成为当前花生生产上存在的突出问题。自无产阶级文化大革命以来,花生产区的贫下 中农,解放了思想,改进了栽培措施,在高产栽培的条件下,采用单粒稀播,达到了高产高倍繁育良种的效果,这一经验推广以来,对加速良种的繁育推广起到很大作用。一九七四年全省高产高倍繁殖新品种面积二万六千多亩。花生良种的高倍繁 Peanut seed with large, low coefficient of propagation, the general output of the field is only equivalent to about ten times the sown, so the promotion and popularization of a new species in the past, it takes more than ten years, therefore, the breeding of peanut breeding to become the current peanut Outstanding problems in production. Since the Great Proletarian Cultural Revolution, the poor peasants and middle peasants in the flower-producing area have liberated their ideas and improved their cultivation measures. By using single-grain thin sowing, high-yielding and high-yielding breeding has been achieved under the conditions of high-yield cultivation. Since the promotion of this experience , To speed up the breeding of breeding to play a big role. In 1974, the province breeds 26,000 mu of new high-yielding breeds. Peanut seed multiplication
