摘  要:
以文冠果播种苗为对象,进行追施氮素试验,结果表明:不同氮素处理对文冠果苗高、地径及生物量均有显著影响,在一定范围内,随着氮素施用量的提高,苗高、地径及生物量的年增长量显著提高,但超过一定施用量,生长量开始下降;文冠果播种苗最佳的氮素施用量为200 mg·m-2。

摘  要:
Nitrogen dressing experiment was carried by using Xanthoceras sorbifolia sowing seedling as the object. The result showed that different nitrogen treatment had remarkable effect on the seedling height,ground diameter and biomass of Xanthoceras sorbifolia. The annual increase amount of seedling height,ground diameter and biomass ascended markedly as the increase of nitrogen application amount in the certain scale. Nevertheless,the growth amount descended as exceeding the certain application amount. The best nitrogen application amount of Xanthoceras sorbifolia sowing seedling was 200 mg.m-2.
