不同抑制剂用量的稳定性肥料对玉米产量的影响
Heilongjiang Agricultural Sciences(2012)
Abstract
玉米是八五三农场的主要农作物之一,为了增加玉米产量,提高经济效益,研究了不同抑制剂用量的稳定性肥料对玉米产量的影响。结果表明:光照充足、积温高、雨水调和的年份,玉米最高产量及最大效益肥料用量、抑制剂品种与用量组合为N-P2O5-K2O=228.0-103.5-84.0+NBPT+DMP(高);春季雨雪偏大,玉米生长季积温低、夏季偏干旱的年份,玉米最大效益肥料用量、抑制剂品种与用量组合为N-P2O5-K2O=180.0-82.8-60.0kg.hm-2+NBPT+DCD(高)。
