【Abstract】 The correlation and path analysis showed that the number of effective spike had the greatest effect on the yield of “Minmai 06”, its partial contribution rate being 54.90%, the number of filled grain per spike had secondary effect on the yield, its partial contribution rate being 19.12%. For high yield (3 375～4 500kg/hm\+2), the effective spikes, filled grains per spike and kilo-grain weight of “Minmai 06” should be (340.8±51.0)×10\+4/hm\+2, 27.2±1.48 and 43.6±3.92g respectively. The results of cultivation test indicated that the optimum sowing date of “Minmai 06” was the last twenty days of November; the proper sowing norm was 150.5～157.5kg/hm\+2; under the condition of applying enough basal manure and three-leaf manure, applying shooting manure at proper dose had obvious effect norw was 150.5～157.5kg/hm\+2; Under the condition of increasing yield.更多还原
