| 摘 要： | 在大渡河干旱河谷3个典型地区(康定市金汤乡陇须村(KJ)、泸定县杵坭乡联合村(LC)、康定市姑咱镇甘孜州林科所苗圃(KG))开展早实核桃品种8518、9818、云新14号和香玲引种栽培试验,并以本地品种为对照,评价早实核桃品种的成活率、保存率以及地径、株高等生长指标,以筛选出适合大渡河干旱河谷地区引种栽培的优良早实核桃品种。研究结果表明:品种和栽植地点显著影响早实核桃品种的成活率、保存率和地径、株高生长量。不同品种核桃幼苗在各栽植地点的成活率、保存率和地径、株高生长量大小顺序均表现为:KG>LC>KJ。香玲品种的成活率、保存率和地径、株高生长量在3个栽植地点均最高,8518品种次之,9818和云新14号品种最低。因此,我们建议在大渡河干旱河谷地区大面积推广早实核桃品种时需充分考虑品种和栽植地区的环境条件,在大力发展本地品种的同时可以引进香玲和8518品种。9818和云新14号品种在大渡河干旱河谷地区的生态适应性较低,不建议在该地区引种栽培。

| Abstract: | The introduction and cultivation experiments of four precocious walnut varieties(i.e.8518,9818,Xiangling and Yunxin 14)combined with the local variety(control treatment)were carried out in three typical areas(Jintang Town,Kangding(KJ),Chuni Town,Luding(LC),Guza Town,Kangding(KG))of the dry valley of the Dadu River.The survival rate,preservation rate,ground diameter and height growth increment of the different precocious walnut varieties were compare to select the most suitable precocious walnut varieties in the dry valley of the Dadu River.The results showed that varieties and planting sites significantly affected the survival rate,preservation rate,ground diameter and height growth increments of the four precocious walnut varieties.All the growth parameters of the four precocious walnut varieties followed the same order of KG>LC>KJ.The survival rate,preservation rate,ground diameter and height growth increments of Xiangling were the highest,followed by 8518 variety,and 9818 and Yunxin 14 varieties were the lowest.Hence,the varieties and environmental conditions of planting sites should be taken into full consideration in promoting the precocious walnut varieties in the dry valley areas of the Dadu River.While vigorously developing local varieties,Xiangling and 8518 varieties can be introduced.However,due to low ecological adaptability of 9818 and Yunxin 14 varieties,it is not recommended to introduce and cultivate them in the dry valley areas of the Dadu river. |
