在前两年试种示范的基础上,1979年营口地区又推广了31万亩杂交粳稻.占全区水稻面积的18.6%,“黎明A×C57”组合约占杂交种80%.1979年春季严重缺水,气温和日照时数均较常年低.据大洼县资料,4～9月大于10℃的活动积温,较常年减少113.8℃.水稻生育最关键时期8～9月,积温比常年减少43℃.但杂交稻依然获得了大丰收.全区约增产4千万斤以上,大部分田块实际亩产超千斤.据大洼县15个农场715个点队的调查,代表面积99,600多亩,杂交稻平均亩产1,071斤.比常规丰锦品种亩产922.9斤,增产11.6%.种植面积最大的平安农场,28,530亩杂交稻平均亩产1,083斤.
Based on the demonstration of the first two years of experiment and demonstration, Yingkou Prefecture in 1991 popularized 31 million mu of hybrid japonica rice, accounting for 18.6% of the rice area in the region and about 80% of the hybrids in the “Dawn A × C57” combination. Severe water shortages, temperatures and sunshine duration were lower than those of normal years.According to the data of Dawa County, the accumulative active temperature of more than 10 ℃ from April to September decreased by 113.8 ℃ compared with that of the normal years.The most critical period of rice growth was from August to September, Reduce the 43 ℃, but the hybrid rice is still a bumper harvest of the region about 40 million kg more yield increase, the actual output of most of the plots per kilogram.According to Dawa County, 15 farms 715 point team survey, representing an area of 99,600 The average mu yield of hybrid rice was 1,071 kg, 922.9 kg more than the conventional Fengjin varieties, an increase of 11.6% .And Ping’an Farm, the largest planted area, with an average yield of 1,083 kg per acre of hybrid rice was 28,530 mu.
