摘　　要：吉林省玉米秸秆及花生壳等农业废弃物年利用率低且资源丰富,本试验研究探讨使用玉米秸秆和花生壳做马铃薯微型薯生产基质的可能性及效果。以吉林省主推品种吉薯1号、尤金、费乌瑞它为试验材料,试验设置3种基质处理(蛭石、玉米秸秆、玉米秸秆与花生壳1∶1混合);3个密度梯度试验(20株/箱、25株/箱、30株/箱)。结果表明:试验品种吉薯1号以玉米秸秆作为栽培基质,栽培密度为25株/箱时,微型薯产量最高;尤金品种以玉米秸秆与花生壳1∶1混合为基质时,在30株/箱的密度下微型薯粒数最多。Jilin Province is rich in agricultural waste resources such as corn straw and peanut shell. This study explored the possibility and effectiveness of using corn straw and peanut shell as substrates for potato mini tuber production. Jishu 1, Youjin and Feiwuruita were used as experimental materials, and three kinds of substrate treatments(Vermiculite, corn straw, 1∶1 mixture of corn straw and peanut shell) were applied, and three density gradients(20,25, 30 plants/box) were set up. The results showed that the yield of micro tuber of Jishu 1 was the highest when the planting density was 25 plants/box and corn straw was used as the cultivation substrate. For Eugene variety, when the mixture of corn straw and peanut shell was 1∶1 as the substrate, the number of micro potato seeds was the largest under the density of 30 plants/box.
