Abstract： This paper introduces the high-yield cultivation and management techniques of rice in the reproductive growth stage of rice growing region in cold region， which mainly includes prolongation of root and leaf functions， adjustment of nitrogen， control of nutrient growth， etc.， so as to achieve thick stem， large panicle， prevent lodging and control premature senile. Through water and fertilizer management， the number of grains per panicle， number of branches and stems per panicle， seed setting rate and 1000-grain weight were increased， and then the yield per unit area was improved.

Key words： Cold region rice; Reproductive growth; Cultivation techniques
