一、精选良种.选用优良健康无病种薯是马铃薯增产的前提。生产实践证明,无霜期较长的二季作地区可选用克新3号、克新1号、金坑白等品种;无霜期短的地区叶选用克新4号、东农303等。如从黑龙江省调种,必须了解种薯产地和退化程度。不准用商品薯代替种薯。如能使用脱毒种薯繁殖的原种、良种或夏播留种的“幼健”秋薯,则增产性能更好。在种薯的调运、贮藏、出薯过程中,随时淘汰病、烂、畸型薯块。
First, the selection of elite. Selection of good healthy disease-free potato is a prerequisite for potato yield. Production practice has proved that the long frost-free period for the second quarter for the area can be used Kexin 3, Kexin 1, Jinkengbai and other varieties; frost-free short areas of the leaf selection Kexin 4, Dongnong 303. If planted from Heilongjiang Province, we must understand the origin of the seed and degree of degradation. Do not use commodity potatoes instead of seed. If you can use the virus-free seed breeding breeds, seeds or summer sowing “young healthy” autumn potato, the yield performance better. In the transfer of seed, storage, the process of potato, at any time out of disease, rotten, abnormal potato pieces.
