摘要
在湖北省浠水县通过大田小区试验,针对水稻品种新两优223作再生稻栽培开展了营养特性与施肥效应研究,基本查明了该品种对氮、磷、钾等养分的吸收规律,种植该品种N、P_2O_5、K_2O的两季推荐总施用量分别为275、95、270 kg/hm^2左右。
Through field plot experiment,nutrition characteristics and fertilizer effects of Xinliangyou 223 that was grown as ratoon rice in Xishui county,Hubei provience,were studied. The basic law of the absorption of nitrogen,phosphorus,potassium was identified. In General,fertilizer applied quantity in the actual production should be about N 275 kg / hm^2,P_2O_595 kg / hm^2,K_2O 270 kg / hm^2.
