摘要
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。
The main cultivation factors of Taishan 021 was studied with the method of innegtive cross of regression factor at three levels in Taian Agricultural Institute and Feicheng country from 1996-1998.The effect of them on the yield was different, the conquest succession was as follow:potassium>seeding time>seeding amount>nitrogen. The investigation on a large area showed that Taishan 021 would achieve the yield of more than 600kg per mu, if it was suitably seeded with 150 thousand plants per mu, nitrogen 18kg per mu and potassium 7.5kg per mu.
