据悉,在脱毒马铃薯种薯的生产繁育中,原原种生产是瓶颈。原原种主要是利用脱毒的试管苗生产的。目前试管苗的繁殖均是先制作培养基,然后在接种室内接种,再置于培养室内进行培养,待试管苗长到一定高度后重复上述过程,如此反复。这种方法存在用药量大、能耗高、用工量大、试管苗生长质量差、成本高等缺点与不足。针对这些问题,四川省达州市农科所积极开展技术 It is reported that in the production and breeding of virus-free potato seed, the original seed production is the bottleneck. The original seed is mainly the use of detoxification of plantlets produced. At present, the multiplication of test tube seedlings is to make medium first, and then inoculated indoors, and then placed in culture room for further training, until the test tube seedlings grow to a certain height repeat the above process, so repeated. This method there is a large amount of medication, high energy consumption, laborious, poor quality growth of test tube seedlings, high cost shortcomings and deficiencies. In response to these issues, Dazhou Agricultural Science Institute of Sichuan Province actively carry out the technology
