摘　　要：在同等的栽培条件下,通过不同的栽培密度,探索马铃薯稻草覆盖免耕栽培的种植密度与产量的关系。试验结果表明,免耕马铃薯产量与栽培密度不成正比,紫花白马铃薯以每1hm2栽培9万株产量最高,效益最好。Under the same cultivation condition, the experiment were conducted to study the effect of different cultivation density with 67 500, 75 000, 82 500, 90 000 and 97 500 plant/hm^2 on potato yield in non-tillage rice field covered with rice straw. The results showed that there was no positive proportional relation between the planting density and the potato yield, the potato cuhivar Zihuabai obtained the highest yield and the best economic benefit when the planting density was 90 000 plant/hm^2.
