少免耕栽培对马铃薯生长发育·产量及经济效益的影响

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。

Effects of Less Tillage and No-tillage Patterns on Growth and Development, Yield and Economic Benefits of Potato(Solanum tuberosum L.)

Objective] The aim was to analyze the effects of less tillage and no-tillage patterns on growth and development,yield and economic benefits of potato.Method] The test analyzed the effects of less tillage and no-tillage patterns on raising seedling situation,growth period,main agronomic characters,yield and economic benefits of potato,comparing with conventional planting pattern.Method] Comparing with conventional planting pattern,less tillage and no-tillage patterns could make potato grow well and had a long growth period;It improved the major agronomic characters,increased the weight of a single potato and the yield increased about 17%.Conclusion] The study provides a reference for finding out a less tillage and no-tillage patterns cultivation technology suitable for Guangdong Area.
