不同栽培方式对小麦生理特性和产量的影响

Effect of Different Planting Patterns on the Physiological Characteristics and Yield of Wheat

为了明确垄作栽培对小麦生理指标和产量性状的影响，研究了平作、垄作1（垄沟内种植1行小麦）、垄作2（垄沟内不种植小麦）等3种不同栽培方式下的小麦生理特性和产量变化。结果表明，无论是NDVI（归一化植被指数）、SPAD值（叶色值）值还是灌浆速率，均是灌浆前增加，到了灌浆期后开始下降；垄作产量大于平作，增产幅度为5．16％～14．52％。垄作栽培与平作相比，有利于产量的形成。

In order to understand the effects of different planting patterns on the physiological characteris tics and yield of wheat, three treatments including flat-planting, bed-planting 1 （one row wheat was plan ted in trench）, bed-planting 2 （no wheat was planted in trench）were setted as the different planting pat terns. The results showed that NDVI, SPAD values and photosynthetic rate all increased before grainfilling stage and decreased after grain-filling stage in bed-planting to flat-planting;The wheat yield of bed planting were about 5.16%～14.52% higher than that of flatplanting.
