皖南烟区烤烟适度规模种植的研究

[目的]为确定适宜单户烤烟的种植规模。[方法]依据皖南烟区现有条件,分析0.33、0.67、1.00、1.33、2.00、2.67、4.00、5.33、6.67 hm2不同种植规模的成本和经济效益。[结果]单户种植规模在2.67~6.67 hm2的投入成本无显著差异,但比种植规模小的成本显著高,种植规模0.33 hm2的成本显著低于其他处理;产值、均价、上中等烟比例等综合经济性状皆以0.33、0.67、1.00、1.33 hm2表现最好,显著高于其他处理,其中0.33 hm2表现最好。单户种植0.33 hm2的纯收入最高,显著高于其他处理。单位面积纯收入与单户种植规模存在明显的负相关。单户种植2.00 hm2的户均综合纯收入最高。[结论]在皖南烟区现有的条件下,单户烤烟种植规模在2.00hm2左右,综合效益最好。

Prelhninary Study on Flue-cured Tobacco with Moderate Scale Planting in South Anhui Tobacco Area

[Objective] The study aimed to ascertain the tobacco planting scale that could be suitable to single household.[Method] Based on present conditions in south Anhui tobacco area,the cost and economic benefit of different planting scales such as 0.33,0.67,1.00,1.33,(2.00),2.67,4.00,5.33 and 6.67 hm2 were analyzed.[Result] The single household planting scale had no significant difference on input cost among each other,when it ranged from 2.67 to 6.67 hm2,but its input cost was significantly higher than that of the smaller scale and the cost of planting scales of 0.33 hm2 was significantly lower than the others.The integrated economic characters such as production value,average value and proportion of superior and medium tobacco of 0.33,0.67, 1.00 and 1.33 hm2 were best and significantly higher than other treatments,in which 0.33 hm2 was best.The pure income of 0.33 hm2 was highest and significantly higher than other treatments.The pure income per unit area obviously negatively related to single household planting scale.The averagely integrated income per household of 2.00 hm2 was highest.[Conclusion] Based on present conditions in south Anhui tobacco area,the integrated economic benefit was best when the tobacco planting scale of single household tobacco was about 2.00 hm2.
