生产超级原种(国外叫原原种)是马铃薯无病毒种薯生产的一个重要环节。超级原种是各级无病毒种薯的基础,超级原种质量的优劣,速度的快慢,成本的高低,都直接影响到各级种薯的质量与推广速度.我们曾用温室、塑料棚、网室三种方法试验,结果证明:用网室生产超级原种,可以降低成本,保证质量,扩大繁殖系数,是一个多快好省的 Production of super seed (foreign called the original species) is a potato virus-free seed production of an important part. Super seed is the basis of virus-free seed seed at all levels, super quality and merits of the original species, the speed of the speed, the level of cost, have a direct impact on the quality and promotion of seed quality at all levels.We used greenhouses, plastic shed , Net room three methods of testing, the results show that: the use of super-net production of net species, can reduce costs, ensure quality and expand the breeding coefficient, is a much faster and better province
