【摘要】 研究了强化栽培条件下杂交水稻配施尿素、过磷酸钙、硅肥的主效应和交互效应与产量的关系,并建立了产量与3种肥料的回归模型。结果表明:施硅肥对水稻增产效果显著;硅肥与磷肥有交互作用,配施适当时增加用量有利于水稻的增产;在特定的条件下,硅肥的施用量为SiO266.0 kg/hm2,水稻产量为8 016.0 kg/hm2。更多还原

【Abstract】 The experiment in the relations among hybrid rice yield and main effects and the interaction of three synthetic measures: different amounts of fertilizer N,P2O5 and SiO2 under the intensified cultivation system was conducted with three factors quadratic regression orthogonal rotational combination design.The result was concluded as follow: the application of SiO2 showed the notable efficiency on hybrid rice yield;the mixture fertilization of SiO2 with P2O5 had significant interaction efficiency;and under the particular condition the best application of SiO2 was 66.0 kg/hm2 for the paddy rice yield was 8 016.0 kg/hm2.更多还原
