摘　　要：于2008年9～12月在宜昌市东部的江汉平原区域枝江市开展了秋马铃薯栽培密度试验。结果表明,每公顷9.0万穴的密度能够以最少的投入得到最大的产投比而获得较高的净收益,是生产商品薯的最佳密度;每公顷15.0万穴的密度投入最多,产量和净收益也最高,但小薯比例高,用于种薯扩繁比较合适;若要同时兼顾商品薯和秋薯留种生产,每公顷12.0万穴的密度可以较好地协调总产量、商品薯率和净收益三者之间的关系。The effect of density on the yield and efficiency of autumn potato was tested in Zhijiang from September to December in 2008. The result showed that the density of 90 000 points per ha was the best for producing goods potato, the net income was higher with less investment. At the density of 150 000 points per ha yield and net income were the highest, but more investment was also needed, and the rate of small potato was larger, this density could be used for the seed production of potato. The density of 120 000 points per ha was better for getting higher output, the rate of goods potato and net income.
