摘　　要：为寻找良好的套种模式和筛选适合广西冬闲桑园免耕套种的马铃薯品种,采用5个青薯系列马铃薯品种进行了冬闲桑园免耕套种试验。结果表明:与常规免耕栽培(CK)相比,青薯系列5个不同马铃薯品种在不同生育时期的株高、茎粗、叶片数等生长性状均表现较好,产量结构得到改善,单株薯重与单株薯数分别提高21.14%和16.32%,鲜薯产量平均提高5.92%,大薯比例平均提高11.94%。在5个青薯系列品种中,以青薯8号的产量最高,平均产量为37 070.37kg/hm2,比CK增产8.98%。桑园免耕套种马铃薯栽培模式可在生产中推广应用,青薯8号是青薯系列马铃薯品种较理想的免耕套种品种。A non-tillage intercropping test of potato varieties of Qingshu series was conducted in mulberry garden in winter to seek a fine intercropping pattern and to screen the suitable potato varieties.The results showed that compared with potatoes of conventional non-tillage cultivation,growth traits of the five potato varieties of Qingshu series were better in different growth periods,such as plant height,stem diameter,leaf number,and the yield structure was improved.Potato weight and potato number per plant were increased by 21.14% and 16.32%,respectively.Potato production and the proportion of larger potatoes were raised by 5.92% and 11.94%,respectively.The yield of Qingshu 8 was the highest（37070.37kg/hm2）,8.98% higher than CK.Therefore,mulberry intercropping potatoes was a new cultivation way to be generalized and applied in the production practice.Qingshu 8 was an ideal potato variety for non-tillage intercropping in mulberry garden.
