| 摘 要： | 利用 195 3- 1993年全国烤烟单位面积产值、产量和上中等烟比重资料 ,将全国视为一个大区 ,划分全国烤烟高低产值、丰歉和优劣质年景 ,研究高低产值年烤烟产值与产量及上中等烟比重之间的关系 ,结果表明 :高产值年每hm2 烤烟平均产值 2 70 3 .0 3元、产量 16 0 8.75kg、上中等烟比重 49.77% ,气象产值、产量和上中等烟气象比重分别占实际产值、产量和上中等烟比重 17.92 %、11.2 4%和 3 .92 % ,由于气象条件有利使单产增加和上中等烟比重提高而增加的产值分别占气象产值 49.71%和 5 0 2 9% ;低产值年每hm2 烤烟平均产值 15 2 4.90元、产量 10 75 .71kg、上中等烟比重 42 .5 6 % ,气象产值、产量和上中等烟气象比重的绝对值分别占实际产值、产量和上中等烟比重 2 9.97%、18.6 9%和 2 .87% ,由于气象条件不利使单产减少和上中等烟比重降低而减少的产值分别占气象产值 5 2 .91%和47.0 9%。

| Abstract: | Five categories of year's in comes i.e.highest,high,middle,low and lowest,were divided based on the output value data per unit area of flue-cured tobacco from 1953 to 1993 in China.The relationship between output value and yield or guality of flue-cured tobacco in high or low income years from its products was studied.The results showed that average yields of flue-cured tobacco got to 1608.75kg/hm 2,with 49.77% of superior-middle grade tobacco leaves,and the average output value 2703.03 chinese yuan/hm 2,percentages of which affected by weather were 11.24%,3.92% and 17.92% respectively in high income years,while in low income years,the average yields of flue-cured tobacco got to 1075.71kg/hm 2,with42.56% of superior-middle grade tobacco leaves,and the average output value only 1524.90 chinese yuan/hm 2,percentages of which affected by weather were 18.69%,2.87% and 29.97% respectively. |
