脱毒微型薯又叫脱毒原原种,是生产原种一代的繁殖材料。山丹县地处河西走廊中段,是典型的大陆性季风气候,春秋天气多风,适宜种植马铃薯的区域在海拔1 800~2 600m。高海拔区域气候冷凉、风速高、病虫害较轻,适宜露地繁育原种。低海拔区域,相对来讲,气候温凉、风速低、易受蚜虫等病毒传播媒介影响,所以 Virus-free microtubes, also known as detoxification of the original seed, is the production of seed breeding material. Shandan County is located in the middle of the Hexi Corridor, is a typical continental monsoon climate, windy spring and autumn weather, suitable for planting potato area at an altitude of 1800 ~ 2600m. Cold climate at high altitude, high wind speed, pests and diseases lighter, suitable for open-field breeding of original species. At low altitudes, relatively cool climates, low wind speeds, and susceptibility to viral vectors such as aphids are relatively low
