从1963年开始,我们在本溪县“五里坡”进行土豆高山留种工作,九年来实践证明,在“五里坡”这样的高山上繁殖从黑龙江省调入的土豆(主要品种是男爵)种薯,可减轻和延缓退化,复壮种性,是自力更生解决土豆种薯一个途径。“五里坡”自然条件特点是:其巅峰海拔1054公尺。土豆繁种地块位于西北坡,海拔700—800公尺,土层厚约1公尺,表土为黑色腐植土。春季气候变化比本地区平地约晚一个“节气”。据1966年观测,“五里坡”的6月份日平均气温15.5℃,耕地的10厘米土温
Since 1963, we have been planting potato and alpine highland in “Wulipo” in Benxi County. After nine years of practice, it has been proven that potatoes transferred from Heilongjiang Province (the baron is the major species) are reproduced in such high mountains as “Wulipo” Seed potato, can reduce and delay the degradation, rejuvenation of the species, is a self-reliance to solve potato seed potato a way. “Five Lips” natural conditions are characterized by: its peak 1054 meters above sea level. Potato plots are located in the northwestern slope, 700-800 meters above sea level, soil thickness of about 1 meter, topsoil is black humus soil. Climate change in spring is about one “solar term” later than the average level in the area. According to the observations made in 1966, the average daily temperature of June in Wulipo County was 15.5 ℃, the soil temperature of 10 cm
