| 摘 要： | 对文冠果、山杏、山桃和柄扁桃等4种能源树种分别在生长季进行了灌溉制度、施肥措施、喷施防落素和在造林时蘸根处理等试验,结果表明：山杏、山桃和柄扁桃的平均株高、平均当年生长量、平均地径、平均分枝数、平均冠幅长和宽等生长特征均是灌溉12次最高,并随着灌溉次数的减少逐步降低;文冠果则是灌溉9次为峰值,并且随着灌溉次数的增多和减少逐步降低。文冠果和柄扁桃以施牛粪最为理想,而山杏和山桃则以施二胺较好。施肥次数方面,文冠果以施肥2次为宜;而山杏、山桃和柄扁桃的各项生长指标表现出施肥3次最好。另外,在造林时对苗木进行蘸根处理可以提高文冠果、山杏、山桃和柄扁桃的生长;在开花期喷施防落素可明显提高文冠果、山杏、山桃和柄扁桃的坐果率,增幅分别为56.06%、50.31%、87.61%和17.37%。

| Abstract: | Based on the test on irrigation system,fertilization measure,spraying PCPA in the growing season and root-dipping treatment during planting for four kinds of energy tree species in Jiuyuan District of Baotou,the results showed that the average height,average current annual increment,average ground diameter,average branch number and average length and width of crown diameter of Prunus sibirica,Prunus davidiana,Amygdalus pedunculata were the highest after irrigating for 12 times and reduced gradually with the... |
