摘　　要：采用四因素五水平二次通用旋转组合设计方法,以1年生木麻黄盆栽苗为研究对象,建立了木麻黄苗期生物量的水肥交互效应方程模型,方程精度高。分析出各因素在不同水平下的边际生物量,结果表明,水肥的合理配施是提高木麻黄生物量和土壤水分利用率的有效途径。According to the all-purpose regression design with four factors and five levels, and based on pot experiments of Casuarina equsetifolia, the model of marginal biomass and coupling effect of water and fertilizer of Casuarina equsetifolia in the seedling stage was established. The results showed that the precision of the model was high. Proper fertilization and watering were effective to improve the Casuarina equsetifolia biomass and utilization vatio of soil water.
