摘要
2021—2022年,在沅江市开展洞庭湖平原碱性土壤条件下,不同栽植深度对香樟生长及香樟黄化病发生的影响研究。结果表明:香樟黄化病感病率较低、成活率最高、生长最快的栽植深度分别为-5~15 cm、0~20 cm、-5~10 cm。综合考虑黄化病、成活率、生长量、造林成本等因素,洞庭湖平原碱性土壤条件下香樟最适宜的栽植深度为0~10 cm。
In order to study the effects of different planting depths on the growth and occurrence of Cinnamomum camphora yellowing disease under alkaline soil conditions in the Dongting Lake Plain,corresponding studies were conducted in Yuanjiang City from 2021 to 2022The results showed that the infection rate of Ccamphora yellowing disease was low,the survival rate was highest,and the planting depth for the fastest growth was-5~15 cm,0~20 cm,and-5~10 cm,respectivelyTaking into account various factors such as yellowing disease,survival rate,growth rate,and afforestation cost,the most suitable planting depth for Ccamphora in alkaline soil conditions in the Dongting Lake Plain was 0 cm to 10 cm.
