中文摘要	在甘肃民勤连古城国家级自然保护区开展了白刺育苗试验研究,探讨了干旱荒漠区育苗措施对白刺苗木生长的影响,结果表明:(1)白刺播种量为30.0 g·m~(-2)比播种量为37.5g·m~(-2)的苗高生长提高了25.7%,地径生长提高了9.1%。(2)白刺种子经ABT浸种后,出苗数比对照(CK)提高了79.1%,出苗开始期和出苗高峰期分别比CK提前7 d和6 d。(3)当覆土厚度为1 cm时,其出苗数比覆土厚度为3 cm提高331.8%。(4)当施肥量为180 g·m~(-2)比施肥量为120g·m~(-2)的当年苗高生长提高41.1%,地径生长提高55.0%;当浇水次数为6次比浇水次数为4次的当年苗高生长提高47.5%,地径生长提高65.3%。(5)7~8月是苗高快速生长期,8月中旬~9月中旬是地径快速生长期。
英文摘要	Nitraria tangutorum seedling experiments were carried out in Minqin Liangucheng National Nature Reserve in Gansu to investigate the effects of cultivation measures on N.tangutorum seedling growth in arid desert area.The results show that(1) N.tangutorum seeding rate(30.0 g·m~(-2)) increased seedling height growth by 25.7% more than that(37.5 g·m~(-2)),increased collar diameter growth by 9.1%.(2)The germination ratio of N.tangutorum seeds soaking by ABT increased by 79.1% than CK,brought forward the seedling emergence beginning stage and peak period respectively earlier 7 days and 6 days than CK.(3) When the covering soil thickness was 1 cm,the emergence number increased by 331.8% than the covering soil thickness of 3 cm.(4) When the amount of fertilizer was 180 g·m~(-2),the seedling height and ground diameter growth increased by 41.1%,55% respectively more than the amount of fertilizer(120 g·m~(-2));when the watering times was 6 times,the seedling height growth and ground diameter growth increased by 47.5%,65.3% respectively more than watering 4 times.(5) From July to August was the fast growth period of seeding height,from mid August to mid September was the fast growth period of seeding ground diameter.
