【摘要】 为探讨氮肥施用技术对小麦"信阳234"产量的影响,采用裂区设计,以基肥施氮量为主区,追肥施氮量为裂区进行试验,结果表明:施用氮肥对小麦"信阳234"产量有极显著影响;追施氮肥对小麦"信阳234"产量有极显著影响;基施氮肥对小麦"信阳234"产量有显著影响;氮肥作基肥施用,对产量的影响同氮肥作追肥施用对产量的关系互作不显著。更多还原

【Abstract】 Research on impact of yield of wheat "xinyang234" by nitrogen applying technology,to adopt Split Plot Design,the experiment that applying dase nitrogen amount is main plot and drilling nitrogen amount is split plot,result shows:applying nitrogen on yield of wheat"xinyang234"have extremely significant influence;Drilling nitrogen on yield of wheat"xinyang234"have extremely significant influence;Dase nitrogen on yield of wheat"xinyang234"have significant influence;Nitrogen fertilizer applying dase,with the yield impact on applying of drilling nitrogen fertilizer made according to the interaction relationship is not significant.更多还原
