‘关山’樱根系分布特征及其对不同施肥处理的响应

Root Distribution Characteristics of Prunus serrulata ‘Kanzan’ and Response of Root System to Different Fertilizer Treatments

摘要

摘要:
目的以‘关山’樱Prunus serrulata ‘Kanzan’为研究对象，探究不同施肥处理对其生长的影响，并筛选出较优的施肥方法。
方法采用根钻法对玉渊潭公园中的‘关山’樱根系进行定点逐层取样，利用Win-RHIZO Pro根系分析系统分析指标。
结果 ‘关山’樱根系的分布主要集中在0～20 cm土层，施肥处理的‘关山’樱根总长度、直径小于0.5 mm根总长度、根投影面积、根表面积和根尖计数等指标明显高于对照组。
结论施肥能有效促进‘关山’樱根系生长，施加深坑复壮基质处理的效果最佳。

Abstract:
Objective The aim of this study is to explore effects of different fertilizer treatments on root of Prunus serrulata ‘Kanzan’ and to select a preferable fertilization scheme.
Methods The root drilling method was used to sample the roots in different soil layers of sampling points in Yuyuantan Park, and Win-RHIZO Pro root analysis system was utilized to analyze root system indicators.
Results The soil layer of 0~20 cm was the main layer where roots of P. serrulata ‘Kanzan’ concentrated. The total root length, root length with d<0.5 mm, root projection area, root surface area and root tips counting in fertilizer treatment groups were higher than those of the group without fertilizer (CK).
Conclusion Fertilization may effectively promote the root system growth of P. serrulata ‘Kanzan’, the optimal effect coming when the sample is treated with the Deep Hole Rejuvenation Substrate.
