探讨了药用甘薯西蒙一号退化机理及对策和栽培措施，结果表明：危害药用甘薯西蒙一号的病毒以甘薯的状斑驳病毒（ＳＰＭＳＶ）和甘薯隐潜病毒（ＳＰＬＶ）为主，为混合浸染方式。这是其种性退化的主要原因。另外，种性退化也和栽培条件密切相关。为此，利用组织培养培育了部分无毒健苗，试验结果表明：药用甘薯西蒙一号脱毒后，叶绿素含量增加了１６．５０％，净光合强度提高了５６．５２％，经济产量系数提高了３６４．７０％。很大程度上恢复了原来的优良种性，使其从病毒病造成的种性退化减产状态中解脱出来，和未脱毒的相比较，无毒健苗栽后，成活返青快，封垅较早，生长势旺盛，发根结薯提早４～５ｄ，有利于光合产物向薯块的运输，产量增加了２．２７１倍。并提出一套相应的增产栽培措施。
The results showed that: the virus that endanger sweet potato Simon No.1 was sweetpotato mottle virus (SPMSV) and sweetpotato latent virus (SPLV) Dipping method. This is the main reason for its degeneracy. In addition, species degeneration is also closely related to the cultivation conditions. To this end, the use of tissue culture to cultivate part of the non-toxic Jianmiao, the test results show that: Simon Sweet potato potato after detoxification, chlorophyll content increased 16.50%, net photosynthetic intensity increased 56.52%, economic yield coefficient Increased by 364.70%. To a large extent, restore the original good nature, make it from the virus disease caused by the reduction of the status of sexual degradation freed, and no detoxification compared to non-toxic health seedlings planted, survival and rejuvenation faster, Early vigorous growth, hair root tuber early 4 ~ 5d, is conducive to photosynthate products to the potato block transport, the output increased by 2.271 times. And put forward a corresponding increase cultivation measures.
