油松和侧柏无纺布容器苗雨季移植试验

目的]研究埋土前取下无纺布容器袋对油松和侧柏苗木生长的影响。方法]以苗龄为2.5年的油松、侧柏无纺布容器苗为试验材料,雨季移植时分为埋土前取下无纺布容器袋(去袋苗)和保留无纺布容器袋(带袋苗)2个处理,移植1年后,调查移植苗成活率,成活苗木株高、地径、高生长量。结果]经χ2检验,去袋苗与带袋苗成活率差异不显著;经方差显著性F检验,去袋苗和带袋苗2个正态总体株高方差差异显著,地径方差差异极显著,高生长方差差异不显著;经t检验,去袋苗和带袋苗株高、地径、高生长量平均值差异不显著。结论]在雨季移植埋土前取下无纺布容器袋对半干旱地区油松、侧柏苗木成活和前期生长无不良影响。

Test on Non-woven Fabric Container Seedlings of Pinus tabuliformis and Platycladus orientalis Transplantation in the Rainy Season

Objective] Influence of removing non-woven fabric container before burying on seedling growth was studied.Method]2.5-year old non-woven container seedlings of Pinus tabuliformis and Platycladus orientalis were used as experimental materials,which were divided into two types:seedling without non-woven fabric container and seedling with non-woven fabric container.The survival rates of transplant seedlings,plant height,ground diameter and height growth of survival seedlings were surveyed after transplanting 1 year. Result] According to χ2 test,survival rates of seedling without non-woven fabric container and seedling with non-woven fabric container had no significant difference .There had signifi-cant differences in the normal population variances of plant height and ground diameter between two kinds of survival seedlings ,but no significant difference in height growth by F test.There had no significant differences in the means of plant height ,ground diameter and height growth between two kinds of survival seedlings by t test. Conclusion] Removing non-woven fabric container before burying in the rainy season had no harmful effects on seedling survival and earlier growth of Pinus tabuliformis and Platycladus orientalis in semi-arid region.
