-
摘要: 种植防风固沙植物是西北干旱、半干旱地区生态环境建设的重要措施,在缺水干旱区及沙漠化地区种植优良固沙灌木极为重要。提出建设优良固沙灌木的种源基地、无性系选择及采穗圃建设、种子园建设、杂交育种和非常规育种与常规育种结合等是开展优良固沙灌木遗传育种的有效途径。Abstract: Planting of windbreak and sand-fixed plants is an important measure for ecoenvironment construction in arid and semi-arid lands of West China.Fine sand-fixed shrubs play the important roles in arid,water shortage and desertificated areas. Some genetic breeding methods are adopted such as establishment of seed source base,clone choice,spike-collecting garden, seed garden, crossbreed and unconventional breeding combined with routine breeding.
