以2年生银杏(Ginkgo biloba L.)幼苗为试验材料,研究了不同剂量的氮磷钾配比对银杏幼苗苗高、地径、冠幅的影响。结果表明,不同剂量的施肥处理对银杏幼苗的生长均有显著的促进作用。处理8效果最好,银杏幼苗的苗高、地径和冠幅均达到了最大值,分别为54.1cm、18.5mm、10.67cm,与对照相比,分别提高31.3%、46.8%、48.19%。
The effects of different N, P and K ratios on seedling height, root diameter and canopy width of Ginkgo biloba L. seedlings were studied. The results showed that different dosages of fertilization treatment on the growth of ginkgo seedlings have a significant role in promoting. Treatment 8 had the best effect. The height, diameter and crown of Ginkgo biloba seedlings reached the maximum value of 54.1 cm, 18.5 mm and 10.67 cm, respectively, which were increased by 31.3%, 46.8% and 48.19% respectively compared with the control.
