摘要
以脱毒三级马铃薯大西洋1号为材料,进行马铃薯免耕不同栽培方式对产量和经济效益影响比较试验。结果表明,在5种栽培方式中,以免耕沟土铺底加6750kg/hm2稻草覆盖种植行的方式最好,马铃薯产量达22245.6kg/hm2,比对照常规翻耕栽培增产6547.2kg/hm2,增产41.7%,每公顷增收3306.7元。因此,免耕沟土铺底加6750kg/hm2稻草覆盖种植行这种栽培方式可以在冬种马铃薯生产中推广应用。
Third virus-free Daxiyang 1 was used as seed potato for the experiment to compare the effects of different no-tillage cultivation models on yield and economic benefit of potato. The results showed that in five cultivation models, the effects of ditch soil on bottom and covering 6750kg/hm^2 rice straw on plant rows were the best, the yield of potato reached 22245.6kg/hm^2. Compared to the conventional cultivation method, the yield increased 6547.2kg/hm^2 with 41.7%, and the increasing income was 3306.7yuan RMB/hm^2, Therefore, this cultivation model could be extended for winter-planting potato production.
