| 摘 要： | 为了探讨辽西地区刺槐(Robinia pseudoacacia)水肥耦合效应,采用3因子5水平正交回归设计方法,用盆栽试验研究探讨了不同水、N、P条件对刺槐苗木生物量的影响.结果表明:水、N对刺槐苗木生物量的作用效果显著,对其具有耦合交互作用;N对刺槐苗木生物量的作用受水分条件制约,不同的水肥配合有不同的生物量积累.因此,以水定肥、合理施肥是提高辽西地区刺槐苗木质量的有效途径. |
| 关 键 词： | 刺槐 水肥耦合 生物量效应 正交试验 |

| Abstract: | An experiment was conducted to study the coupling effect of water,nitrogen and phosphorus on the biomass of Robinia pseudoacacia potted seedlings by regression design with three factors and five levels,aiming to seek the optimum quantity of water and fertilizer.Results showed that water and nitrogen had obvious effects on the biomass of R.pseudoacacia seedlings,and the effect of nitrogen on seedling biomass was influenced greatly by water.The coupling effect on the biomass was produced by the combination of... |
