摘　　要：广西桑园种植面积不断扩大,但对冬闲桑园开发明显不足。为提高桑园经济效益,增加桑农收入,2009年冬开展桑园套种冬种免耕栽培马铃薯试验研究。本试验结果表明,与常规免耕栽培马铃薯相比,套种马铃薯出苗较快而齐,株高、茎粗、叶片数等生长性状表现良好,产量结构得到改善,增产效果比较明显,大、中薯比例得到明显提高。可见,桑园套种冬种免耕马铃薯是广大桑农增效创收的一种新的栽培模式。Area of mulberry cultivation is expanding unceasingly in Guangxi, but development of winter fallow mulberry garden has obviously insufficien , for improving economic efficiency of mulberry, increasing farmers＇ income. In winter 2009, an experiment of mulberry intercropping potatoes with winter non-tillage cultivation was cnducted. The results showed that compared with con- ventional non-tillage cultivation, seedling of intercropping potatoes emerged rapidly and homogeneously, growth features were better, such as plant height, stem diameter, leaf numbers. Yield was increased obviously, the proportion of larger potatoes and middle potatoes were increased obviously. It is clear that mulberry intercropping potatoes is a new cultivation way to increase efficiency and income for farmers.
