天然繁种基地山西境内除盆地外,山峦起伏、沟壑纵横、山川交错,形成各种天然屏障,隔离区安全,制种纯度高;海拨大都在1000米以上,光照充足、通风透光、结实率高;昼夜温差大,干物质积累多,制种产量高,千粒重大。气候差异自然形成了极早熟、早熟、中熟和晚熟四大制种区,可以生产“两杂”各类种子。山西中北部恒山、五台山、太行山和太岳山高耸挺拔,巍峨壮丽,气候凉爽,土壤肥沃,是生产繁殖马铃薯的好地方。特别是五台山,是我国少有的无桃蚜区,马铃薯无病,不退化。
In addition to the natural breeding base in Shanxi basin, the undulating hills, ravines aspect, mountains and rivers staggered to form a variety of natural barrier, isolation zone security, high purity seed production; mostly in the 1000 meters above sea level, adequate lighting, light and light, strong High rate of temperature difference between day and night, dry matter accumulation, seed production, grain weight. Climatic differences naturally form a very early maturing, early maturing, medium maturity and late maturity of the four major producing areas, can produce “two hybrid ” all kinds of seeds. Shanxi north-central Hengshan, Mount Wutai, Taihang Mountain and Taiyue Mountain towering tall and majestic, majestic magnificent, cool climate, fertile soil, is the production of a good place to reproduce the potato. In particular, Mount Wutai is rare in China, no peach aphid area, disease-free potato, does not degenerate.
