宿根花卉抗旱性研究进展

Research Advance on Drought Resistance in Perennials

为探讨抗旱节水型宿根花卉评价及筛选方法,缓解节水与绿化面积增加的矛盾。归纳总结了宿根花卉的特点、宿根花卉的评价筛选、植物抗旱性评价方法及抗旱型宿根花卉的应用概况。国内目前的抗旱性研究主要集中在生理机理及理论层面,抗旱型宿根花卉应用范围虽然比较广泛,但是种类较单一,配置方式不合理,且没有与之相配套的节水灌溉技术。

The way to evaluate and screen drought-resistant and water-saving perennials was explored to promote the application of these perennials and ease the contradiction of water-saving and landscaping. The characteristics of perennials and the method to screen perennials and evaluate drought resistance, as well as the general situation of drought-resistant perennials application were summarized. It showed that at present in our country, the study on drought resistance mainly concentrated in the physiological mechanism and the theoretical level,through the application of drought-resistant perennials relatively broad, the species was simple, and configuration mode was not reasonable, and there was no matching of water-saving irrigation
