摘　　要：研究了6种覆盖模式对免耕马铃薯农艺性状和产量的影响,结果表明:在覆盖稻草的基础上加盖薄膜对免耕马铃薯苗期生长动态、株高、冠幅、干物质重量以及产量形成等均有显著影响。其中,出苗率、株高、冠幅、干物重和单株产量最高的是免耕覆盖4 cm水稻秸秆后盖白色膜处理,经济产量最高的是免耕覆盖4 cm水稻秸秆后盖黑色膜处理,免耕覆盖8 cm水稻秸秆后盖黑色膜处理的绿薯率最低。The effects of six mulching treatments on agronomical characters and yield of no - tillage potato were studied in the paper. The result indicated that straw mulching plus plastic membrane had significant effects on seedling growing trend, plant height, crown width, dry weight and yield per plant of no-tillage potato. Among the six treatments, the germination rate, average plant height,crown width,dry weight and yield per plant were the best for treatment 3; the economic output was the highest for treatment 5; the rate of green potato was the lowest for treatment 6 ; the rate of rotten potato was the lowest for treatment 3; and the rate of commercial potato was the highest for treatment 6.
