脱毒马铃薯生产栽培技术

Production and Cultivation Technology of Virus-free Potato

嫩江县位于黑龙江省西北部,土质肥沃,林、草、水源丰富,具有优越的地理位置和丰富的自然资源。该地区昼夜温差大,有利于马铃薯块茎淀粉的积累,所以种植的马铃薯产量高,且品质好。为了充分利用脱毒马铃薯的无病毒感染、结薯早、膨大快、产量高和品质好等优点,总结了适合该地区的脱毒马铃薯高产高效栽培技术,包括品种选择与种薯处理、选地整地、合理施肥、田间管理、病虫草害防治以及收获贮藏。

Nenjiang county is located in the northwest of Heilongjiang province, where soil is fertile, and resources of forest, grass, and water are dch, having supedor geographical position and dch natural resources. The temperature difference between day and night is big in this region, which is suitable for starch accumulation in potato tuber, leading high yield and good quality of potato. In order to make full use of the feature of virus-free potato which include no virus infection, early tuber setting, bulking fast, high output and good quality, high yield and high efficiency cultivation technology of virus-free potato in this region were summarized, such as variety selection, seed tuber treatment, land choosing and operation, rational fertilization, field management, pest, disease and grass control and prevention, harvest, and storage.
