不同免耕覆草栽培模式对马铃薯农艺性状和产量的影响

Effects of Different No-tillage Cultivation Patterns with Straw Cover on Potato Agronomic Traits and Yield

为探究免耕覆盖栽培对马铃薯生长发育及产量的影响,为其免耕栽培提供技术支撑。设计免耕稻草覆盖(T1)、免耕稻草覆盖+地膜覆盖(T2)、免耕稻草覆盖+地膜覆盖+小拱棚(T3)、免耕覆土栽培(CK)4种免耕栽培模式,研究不同免耕栽培模式对马铃薯农艺性状及产量的影响。结果表明,T3栽培模式各项农艺性状最优,产量最高。综合生产成本、推广方式等因素,T2栽培模式经济效益高,操作简便,更适于大面积推广。

This study focused on the effects different no-tillage cultivation patterns on potato agronomic traits and yield,4kinds of cultivation patterns were designed as follows：T1,no-tillage straw cover;T2,no-tillage straw cover ＋ plastic film mulching;T3,no-tillage straw cover ＋ plastic film mulching ＋ plastic tunnel;CK,no-tillage covered by soil.The results showed that the potato quality was best and had highest yield by using the treatments of no-tillage straw cover＋ plastic film mulching.The cultivation model is suitable for extending widely.
