心叶驼绒藜(Ceratoides ewersmanniana)具有良好的水土保持和防风固沙功能,在新疆荒漠草地植被恢复和生态建设中具有重要作用。本研究采用10个不同密度处理,探索播种密度对心叶驼绒藜生长性状和生产性能的影响。结果表明,播种密度对心叶驼绒藜生长发育、生产性能等影响很大。低密度的个体生长发育好,能形成生殖枝,达到相对高产,故认为在无灌溉条件下最合理的密度为4～30株.m-2,留苗2 666～20 000株.667m-2。北疆心叶驼绒藜人工种植和天然补播改良草地中可适当降低播种密度。以上结果可以为心叶驼绒藜人工种植和改良草地确定合理种植密度提供科学依据。
Ceratoides ewersmanniana has good functions of soil and water conservation and windbreak and sand fixation, and plays an important role in vegetation restoration and ecological construction of desert grassland in Xinjiang. In this study, 10 different density treatments were used to explore the effects of planting density on the growth traits and performance of Ceratoides arborescens. The results showed that sowing density had a great influence on the growth and development of Ceratoides arborescens. Low-density individuals grow well and can form reproductive branches, to achieve relatively high yield, so that under no irrigation conditions, the most reasonable density of 4 to 30 strains. M-2, Lvmiao 2 666 ~ 20 000. 667m-2 . Artificial planting of Ceratoides arborescens in North Coreana and natural replanting improved meadow planting density can be appropriately reduced. The above results can provide scientific basis for Artificial cultivation of Ceratoides lanatus and improved planting density.
