1978年以来,我县芝麻生产有了很大的发展,面积由1979年以前的3～4万亩,扩大到1979年至1984年的7～8万亩,已稳定下来。1979年芝麻平均亩产73公斤,1980年因淹水亩产18.5公斤;1981年亩产又达74.5公斤;1982年下降到亩产45公斤;1983年因多雨受渍亩产16公斤,1984年又上升到亩产69公斤。由此可见,芝麻产量极不稳定。通过我们调查分析, Since 1978, the production of sesame in our county has been greatly improved. The area has been stabilized from 300,000 to 400,000 mu before 1979 and from 70,000 to 80,000 mu between 1979 and 1984. In 1979, the average yield of sesame seeds was 73 kilograms. In 1980, it was 18.5 kilograms per mu of flooding. In 1981, the yield reached 74.5 kilograms. In 1982, it dropped to 45 kilograms per mu. In 1983, it was 16 kilograms per mu It rose to 69 kg per mu. This shows that the output of sesame is very unstable. Through our investigation and analysis,
