我区种植杂交稻已有四年,1979年已发展到250万亩。四年来,收成两丰两欠,1976年试种单季杂交稻350亩,平均亩产1100斤;1977年扩至41.7万亩,单产降到758斤;1978年气候条件有利,195万亩平均亩产850斤;1979年受灾单产又降到785.7斤。从目前生产条件来看,约有60％的面积已经具备了亩产千斤左右的条件,但实际产量差距还很大。 I have been planting hybrid rice four years, 1979 has grown to 250 million mu. In the past four years, two crops have been bred in Liangfeng County. In 1976, 350 mu of single-season hybrid rice was planted with an average yield of 1100 kg per mu; in 1977, it was expanded to 417,000 mu with a yield of 758 kg per mu. In 1978, the climate was favorable with an average of 1.95 million mu Yield 850 kg per mu; affected yield in 1979 dropped to 785.7 pounds. From the current production conditions, about 60% of the area already has the condition of about a kilogram per mu, but the actual production gap is still large.
