我省的马铃薯生产由于病毒为害,导致种薯退化,难于就地留种。为解决种薯问题,不得不年年由高纬度地区调种,全省年调种量达三千至五千万斤。调来的品种生育期偏长,不适合我省两季栽培,或混杂病烂,单产不高。因此,为生产提供优良种薯是发展我省马铃薯生产亟待解决的问题。 Due to virus damage in potato production in our province, it leads to the degeneration of seed potatoes and makes it hard to stay in place. In order to solve the problem of seed potato, it has to be planted annually in high latitudes, and the annual planting of the province amounts to 3,000 to 50,000 kilograms. Transferred to the breed is too long, not suitable for cultivation in our province for two seasons, or mixed disease rotten, yield is not high. Therefore, to provide excellent seed production for the production of potato in our province is an urgent solution to the problem.
