氮磷钾配比施肥对银杏幼苗生长的影响
|
摘要
为了筛选我国北方地区彩叶树种银杏生长中较好的施肥配方,开展了氮磷钾3因素3水平的施肥正交试验,结果表明:氮磷钾不同配比处理对银杏树高、地径、叶片生长等生长因子有着明显的促进作用,其中纯N 4.6 g·株~(-1)、纯P 6.4 g·株~(-1)、纯K 1.1 g·株~(-1)的处理组合对苗高以及单株叶质量增加效果最好,纯N 9.2 g·株~(-1)、纯P 3.2 g·株~(-1)、纯K 1.1 g·株~(-1)的处理组合对地径以及单叶质量的增加效果最明显。
In order to screen the optimal fertilization formula of the growth of the color-leaf tree species--Ginkgo biloba in northern China, the orthogonal experiment of nitrogen, phosphorus and potassium three factors and three levels of fertilization was conducted. Result shows that the different formulas of NPK treatment on tree height, ground diameter, leaf growth of Ginkgo biloba have obvious promoting effects. The treatment combination of pure N 4.6 g tree~(-1), pure P 6.4 g tree~(-1 )and pure K 1.1 g tree~(-1) has the optimal effect on seedling height & leaf mass per plant. The treatment combination of pure N 9.2 g tree~(-1), pure P 3.2 g tree~(-1), and pure K 1.1 g tree~(-1) have the most obvious effect on the increase of ground diameter & single leaf quality.
