[目的]分析少免耕栽培方式对马铃薯(Solanum tuberosum L.)产量和经济效益等的影响。[方法]通过少免耕栽培与常规栽培对比试验,研究少免耕栽培对马铃薯出苗、生育期、主要农艺性状、产量及经济效益的影响。[结果]在该试验条件下,与常规栽培相比,少免耕栽培的马铃薯长势好,生育期长;马铃薯主要农艺性状都有所改善,单薯重量增加,产量增加17%左右。[结论]该研究可以为探索一套适宜广东地区马铃薯少免耕种植的栽培技术提供参考。
[Objective] The research aimed to analyze the effects of no-tillage cultivation methods on yield and economic benefits of potato (Solanum tuberosum L.). [Method] The comparative experiment of no-tillage cultivation and conventional cultivation was conducted to study the effects of no-tillage cultivation on potato emergence, growth period, major agronomic traits, yield and economic benefits. [Result] Under this test condition, the pots with less no-tillage cultivated had better growth and longer growth period compared with the conventional cultivation. The main agronomic traits of potatoes all improved, the weight of single potato increased, and the yield increased about 17%. [Conclusion] This study could provide a reference for exploring a set of cultivation techniques suitable for potato cultivation in Guangdong.
