马铃薯夏播留种是防止马铃薯退化的有效措施，夏播在凤城市区已有３０ 多年的历史，而夏播留种的关键技术是种薯的安全度夏。通过对“半地下种薯冷贮库”、“柞蚕半地下保种库”、“小土冷窖”、“土冰窖”、“冷凉处散藏法”５ 种贮藏技术的试验研究和比较鉴定，以“半地下种薯冷贮库”、“柞蚕半地下保种库”、“小土冷窖”贮藏种薯效果较为理想，每年的４ ～６ 月份的库（ 窖） 温都能够控制在５ ℃以内，出库时种薯发芽率和腐烂率均不超过１ ％ ，出库时的种薯处理与入库前的鲜薯一样
Summer sowing of potato is an effective measure to prevent the degeneration of potato. Summer sowing has been in Fengcheng urban area for more than 30 years and the key technology of summer sowing is seed summer safety. Through the experimental research and comparison of five kinds of storage technologies, such as “semi-underground seed potato cold storage”, “Tussah semi-underground preservation”, “small soil cold pit”, “soil ice cellar” Identification, to “semi-underground seed potato cold storage”, “Tussah semi-underground preservation of seed banks”, “small soil cold pit” storage of seed is better, from April to June each year (cellar) temperature can be controlled At less than 5 ℃, the germination rate and decay rate of the seed tub are no more than 1% when leaving the warehouse.
