Heilongjiang Province is high cold rice region in north China, the gifted favorable natural resources is very much suitable for developing rice production. But because of the historical reason, Cultivated area wandered up and down in 137,000~245,500 hectares from 1955 to 1983, The yield per hectare was 2535~4482 kilograms, belong to a low yield rice area in our country, with little cultivated area, not high and changing a bigger yield per unit area. After popularizing the technology of drought grows seedlings and plant rarely in 1984, great change and development took place in cultivation technique, the per unit area yield was relatively low yet, 4744.77 kilograms / hectare from1985 to 1994. For this reason, “the comprehensive technical research and demonstration of high yield on large area” was carried out in 1995. The result showed that the cultivated area was 390,000 hectares on average every year, account for 29% of the whole province area 135.62 million hectare on average during the same period, the yield per unit hectare 7893 kilograms on average, had increased by 37.3% than the past 5 years average output 5748.57 kilograms / hectare and 32.9% than the average yield in whole province at the same time. In this paper, it was also indicated the future development prospect and a further shift way in yield potential in Heilongjiang province.
