在多年的绿化施工中,我们发现在同样的养护条件下,广玉兰的成活率相对其他常用树种较低。无论当年栽植的,还是第一年已成活的二三年生苗木,夏季都会出现部分死亡现象。经过多年的观察和尝试,我们初步了解了造成死亡的部分原因和提高成活率的办法。成活率偏低原因分析1、广玉兰性喜肥沃湿润而排水良好的土壤,不耐干燥,在土壤干燥处生长会变慢且易变黄,在排水不良的黏性土和碱性土中生长 In many years of greening construction, we found that under the same conservation conditions, the survival rate of Magnolia relative to other commonly used species is lower. No matter what year planted, or the first year have been living two or three year seedlings, the summer will be part of the death phenomenon. After many years of observation and trial, we have initially learned some of the causes of death and ways to improve the survival rate. Survival rate is low Cause 1, Magnolia Sexes fertile moist and well-drained soil, intolerant of dryness, growth in the soil will be slow and easy to turn yellow, poor growth in poorly cohesive soil and alkaline soil growth
