1996～ 1998年在泰安市农科所和肥城市边院镇采用小区试验与大田调查相结合的 4因素 3水平正交法 ,研究大穗型小麦泰山 0 2 1高产的主要栽培要素。结果 4种栽培要素的效应依次为 :钾肥 >播期 >播量 >氮肥 ;大田调查表明 ,泰山 0 2 1小麦适期播种 ,基本苗 2 2 5万 /hm2 ,氮肥 2 70kg/hm2 ,钾肥 112 .5kg/hm2 ,产量可达到 90 0 0kg/hm2 以上。
From 1996 to 1998, the main factors for high yielding of large-panicle wheat, Taishan 021, were studied using the 4-factor-3 orthogonal test combining plot test and field investigation in Tai’an Agricultural Science Institute and Beiyuan Town of Feicheng City. Results The effects of four cultivation elements were as follows: potash> sowing date> sowing rate> nitrogen fertilizer. The field survey showed that 021 Taihe wheat was sown properly, 225,000 hm2 basal seedlings, 2 70kg / hm2 nitrogenous fertilizer and 112% .5kg / hm2, the output can reach 90 0 0kg / hm2 above.
