【摘要】 文冠果适应性广,种子含油率高,是我国北方特有的油料树种,但播种苗容易弯曲倒伏,这影响了苗木的质量和生物质能源基地的建设质量。为了确定最佳的育苗密度,培育苗干通直的合格苗木,于2007~2009年进行了9个密度的播种育苗试验。结果表明:播种苗育苗的最佳密度为8 cm×30 cm、8 cm×40 cm,在这两个育苗密度下,播种苗的苗干通直,地径和苗高均较大。更多还原

【Abstract】 Xanthoceras sorbifolia has wide adaptability and high oil production of the seed,it is a particular oil tree species in the north of China,but the seedling is easy bend and lodging,so that it has effect on the seedling quality and the construction of biomass energy station.To decide the best density of cultivation and culture the straight trunk of qualified seedling,seedling cultivation trial of 9 density gradients from 2007 to 2009 was carried out.The results showed that cultivation densities of 8 cm×30 cm and 8 cm×40 cm were the best density of seedling cultivation in trial region,the seedling had straight trunk,greater basal diameter and seedling height at the 2 kinds of cultivation densities.更多还原
