不同耕作方式及前茬作物对冬小麦产量的影响

Effects of Different Tillage Methods and Previous Crops on Winter Wheat Yield

为了研究不同耕作方式及前茬作物对冬小麦产量的影响,以长6878为供试材料,采用二因素裂区设计,探索在不同耕作方式及前茬作物共同影响下冬小麦产量的表现情况。结果表明,冬小麦的产量表现为旋耕处理显著高于翻耕处理,玉米茬的产量较高。耕作方式的改变,对各茬口的冬小麦穗密度、谷草比、经济系数影响不显著;相同茬口下,旋耕比翻耕更有助于冬小麦穗长、穗质量、结实小穗数的增加以及不结实小穗的减少,对产量的增加有着一定的积极作用。

To study the effects of different tillage methods and previous crops on winter wheat yield,this study used Chang 6878 as the test material,and used two-factor splitting design to explore the performance of winter wheat yield under the effects of different tillage methods and previous crops.The results showed that the yield of winter wheat under rotary tillage was significantly higher than that of tillage treatment,and the yield of corn borer was higher.The change of tillage mode had no significant effect on the ear density,grain-grass ratio and economic coefficient of winter wheat.Under the same mouth,rotary tillage was more conducive to the increase of ear length,ear quality and number of spikelets in winter wheat than in tillage.The reduction of firm spikelets had a positive effect on the increase in yield.
