摘要: 干旱环境中,植物在种子期对极端环境的忍耐能力最大,而幼苗期忍耐能力最小。幼苗为适应环境几乎耗尽自身能量,完全依赖自身的抗逆能力并不能完全得到健壮的植株和理想的建植效果。因此,该研究设计华北驼绒藜种子覆膜直播试验,通过播深、水分和施肥等不同处理,研究其在干旱荒漠草原区建植的技术。结果表明,华北驼绒藜种子易于浅播种,播深适宜1~2cm。覆膜直播利于提高幼苗的出苗率和保苗率。均分别高于对照8.32%和13.12%;水分是决定成苗率的重要因素,适度的干旱能够促进根系深长生长;施种肥对华北驼绒藜成苗有促进作用,对当年的地上生物产量影响较大。

Abstract: In the drought environment, the staged-seed of Ceratoides arborescens had the maximum endurance ability to extreme environment,but the minimum for seedling period. In order to adapt the environment,the seeding nearly exhausted its own energy, it was not possible to get healthy plant if completely depending on their resistance ability. Thus, this study designed Ceratoides arborescens seeds direct sowing with plastic film test, by the treatments of sowing depth, water and fertilizers applied to research it's cultural technology in arid desert grassland area. The results showed that suitable sowing depth for Ceratoides arborescens seeds was 1-2 cm; direct sowing with plastic film could improve the seedling emergence rate and seedling rate, 8.32% and 13.12% higher than the control respectively. Moderate dry could promote the growth of root, but seedling rate was depended on water. Applied fertilizers would improve the seedling growth and bio-yield of Ceratoides arborescens.
