采用随机排列法,在桦甸市冲积土进行扩展“3414”施肥对玉米产量及产值的影响试验。结果表明,施肥量为纯N 180 kg/hm2、P2O5105 kg/hm2、K2O 80 kg/hm2时能获得较高产值,该结果可为该区域玉米优质高效生产提供有力的技术支持。
Effects of spreading “3414” fertilization on yield and output of corn in alluvial soil of Huadian City by using random arrangement method. The results showed that the high yield could be obtained when the fertilizer was pure N 180 kg / hm2, P2O5105 kg / hm2 and K2O 80 kg / hm2, respectively. The results could provide strong technical support for the high quality and efficient production of maize in this area.
