解放以来,梅县地区水稻生产水平有很大提高。从1949年至1986年的37年统计,总产由3.6亿公斤上升到9.81亿公斤,增长158.16%,平均每年递增4.27%;单产由117公斤增加到302公斤,增长158.12%,年递增4.27%。三十多年来水稻生产虽然有了发展,但是应该看到,年度间增长是不平衡的,总产时高时低,其中50年代平均增长3.5%,60年代平均增长4.25%,70年代平均增长1.88%,80年代平均增长4%。在37年中,增产的有20年,减产的有11年,保产的有6年。以最近80年代6年统计为例,其中增产的2年,减产的3年,平产的1年。为什么会出现这种起伏的变
Since the liberation, the rice production in the Meixian area has greatly improved. In the 37-year statistics from 1949 to 1986, the total output increased from 360 million kg to 981 million kg, up 158.16% with an average annual increase of 4.27%. The yield per unit increased from 117kg to 302kg, up by 158.12% with an annual increase of 4.27% . Over the past 30 years, although rice production has been developed, it should be noted that the annual growth is uneven and the total production is high and low, with an average growth of 3.5% in the 1950s, an average growth of 4.25% in the 1960s and an average of 70s in the 1970s An increase of 1.88%, an average increase of 4% in the 1980s. In 37 years, there have been 20 years of increased production, 11 years of reduced production and 6 years of guaranteed production. Take the statistics of the recent sixties of the 1980s as an example, with two years of increase, three years of reduction and one year of stable production. Why there is such a change of ups and downs
