摘要
为探究播种方式对大别山区丹桂的育苗效果,本试验采用样方调查法,分析了试验地采用春播与秋播的苗木出芽率和苗高等生长状况。结果表明,秋播较春播优势明显,良种壮苗率显著提高。秋播种子较春播早10d出芽,播种70d后发芽率达93%,较春播提高17个百分点;一年生秋播苗株高、地径较春播苗分别增长25.8%和40.0%。本文为丹桂在高海拔地区的推广种植提供参考。
To investigate the effect of sowing methods on the seedling rearing of Osmanthus fragrans var.aurantiacus in Dabie Mountain,the quadrat survey method was used to analyze the germination rate and seedling height growth of the seedlings sown in spring and autumn.The results showed that autumn sowing had obvious advantages over spring sowing,and the rate of good varieties and strong seedlings increased significantly.Autumn sowing seed germination 10 days earlier than spring sowing.The germination rate of autumn sowing reached 93%after 70 days of sowing,which was 17 percentage points higher than that of spring sowing.Compared with spring seedlings,the plant height and ground diameter of annual autumn seedlings increased by 25.8%and 40.0%,respectively.This paper provides references for the cultivation and popularization of Osmanthus fragrans var.aurantiacus in high altitude area.
