选用脱毒品种青薯2号,采用地膜垄作方式栽培,试验表明,当地马铃薯适宜播期为4月20日—4月25日,适宜密度为67500—75000株.hm-2,产量可达44t.hm-2。
Virus-free Potato Qingshu No. 2 was cultured by ride planting and covering with film. The results showed the best sowing date was 20th-25th April in the place. The best density was 67500 - 75000 plants·ha^-1. the yield will be 44t·ha^-1.
