二次通用旋转组合设计下耐旱树种的生长特性研究

Study on Growth Characteristics of Drought Tolerant Tree Species under the Second Universal Rotary Combination Design

植物修复是干旱半干旱地区铅污染土壤修复的有效手段之一。本文以1年生紫穗槐为研究材料,采用三因素二次旋转组合设计,分析了不同生长阶段节律性供水对紫穗槐生长特性的影响,旨在寻求适于植株生长的最佳供水组合,为干旱半干旱地区水资源合理利用提供参考。

Phytoremediation is one of the effective means of soil lead pollution remediation in arid and semi-arid region. Using quadratic regression rotary design of three factors, this paper mainly analyzes the effects on growth characteristics of rhythmic water supply at the different growth stages of annual Amorpha fruticosa seedlings, which is helpful to seek the best combination of water supply suitable for plan＊ growth. The results in the paper provides reference for rational utiliza- tion of water resources in the arid and semi-arid areas.
