采用微区试验方法,设4个不同处理,研究了夏玉米简化施肥技术。试验结果表明,从玉米增产效果来看,玉米专用肥一次性底施>等养分量BB肥>常规施肥>尿素表施。以玉米专用肥一次性底施增产效果最好,比对照增产20.6%,达极显著水平,比BB肥增产14.84%,达显著水平,比尿素表施增产27.61%,达显著水平。从施肥方法来看,表施尿素增产最差,不宜提倡。玉米专用肥一次性底施增产效果最好,可以推广。
Using the micro-zone test method, four different treatments were set up to study the simplified fertilization technology of summer maize. The results showed that corn yield increased from the point of view, a one-time special fertilizer corn bottom> equal nutrients BB fertilizer> conventional fertilization> urea table. Fertilizer with corn at the end of the best one-time yield increase, 20.6% increase compared with the control, reaching a significant level, compared with BB fertilization increased 14.84%, reaching a significant level, 27.61% higher than urea yield, reaching significant levels. From the point of fertilization method, the table urea yield the worst, should not be promoted. Fertilizer corn at the end of a one-time yield the best, can be promoted.
