摘要
应用LOTUS1-2-3图表分析集成软件,对芽苗不同截根移栽处理与对照进行比较分析。结果表明:芽苗截根移栽后,能有效地抑制主根生长,促进侧根生长发育,且高径比下降23.4%,T-R率下降22.3%,苗木全株干重增加51.1%;截根能使苗期的地上与地下部分生长趋于协调,图示聚类分析还表明,截根处理以保留根毛区约2/4-3/4根长为宜。
The
results indicated that after cutting the roots of bud seedlings and transplanting them,the mainroot
growth could be effectively inhibited,the lateral root growth and development could be
promoted,theratio of height to diameter decreased by 23.4%,the T-R rate decreased by 22.3%,the
dry weight of aseedling increased by 51.1% and cutting the roots could make the growth of the
above-ground part and thebelow-ground part tend to coordination in the seedling stage.
