摘要
在湖北省京山县通过大田小区试验,针对水稻品种准两优608作再生稻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,该品种N、P_2O_5、K_2O的两季推荐总施用量分别为340、110、230 kg/hm^2。
Through field plot experiment,nutrition characteristics and fertilizer effects of Zhun-liang-you 608 grown as ratoon rice in Jingshan of Hubei provienee 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 340 kg/hm2, P205 110 kg/hm2, K20 230 kg/hm2.
