不同耕作方式对成都平原麦稻轮作模式下小麦生长及产量的影响

Effects of Conservation Tillage on Wheat Quality with Wheat and Rice Rotation Mode

为了明确不同耕作方式对成都平原小麦生长及产量的影响,进行了麦—稻轮作、麦免稻旋、麦免+稻旋+秋作、麦稻双免、麦稻垄作5种耕作方式定位试验,研究不同处理下小麦生长发育和产量的变化。结果表明:不同耕作方式对小麦生长及产量的影响达到显著差异,其中麦免稻旋模式产量最高。免耕不仅对小麦苗期生长、成穗、干物质积累均影响较大,而且可显著提高小麦产量,并且省工、培肥、效益好,可作为成都平原的主要耕作模式。

Experiments were conducted to investigate differences of wheat quality under different conservation tillage ways with the wheat and rice rotation mode in West Sichuan Plain.Five cultivation ways were designed,including wheat-rice rotation,wheat free-rice rotation,wheatfree-rice rotation-autumn planting,double-free of wheat and rice,and wheat ridge-rice free.The results showed that wheat free-rice rotation had the maximum actual output,leaf area index and biological yield.
