| 摘 要： | 用盆栽的方法,采用三因素五水平D-饱和优化设计,以采自于辽宁东部的酸性水稻土为供试土壤。对氮、磷、硅肥用量与水稻产量之间的关系进行研究,建立了水稻产量函数模型;结果表明,氮、磷、硅肥均能显著地影响水稻产量,其作用大小依次为氮肥>磷肥>硅肥,获得最高产量的施肥方案N、P2O5和SiO2分别为0.248、0.129和0.0001g/kg土。

| Abstract: | Pot experiments were conducted with rice by A- D optimum design of three factors and five levels to study the effects of combination of N, P and Si on rice yield in acid paddy soil. Soils were collected from Eastern Liaonmg. Results indicated that yields were affected by N and P fertilizer significantly at 1 % and 5 % levels, respectively, but not significantly by Si. Highest rice yields were obtained with the combination of N 0.248, P2O5 0.129 and SiO2 0.0001g·kg-1 soil. |
