摘要
银杏２年生实生苗根系干鲜重均为茎的１．３倍，苗茎含水量５８．６８％、根系为６６．７４％，平均苗木含水量６３．０６％，根系含水量是茎的１．１４倍。浸水天数与苗木吸水率和含水量、日晒天数与失水率之间呈显著的正相关，日晒天数与含水量呈显著的负相关。银杏边起苗达栽植或清水浸根１ｄ成活率最高，栽植时苗木含水量应控制在５２％以上为宜。
Dry and fresh weight of 2 - year Ginkgo biloba seedling root system was 1. 3 time of stem. Moisture content of stem was 58. 68%,of root system was 66. 74%, average was 63. 06%. Days for water immersion had evident positive relation with water absorption of moisture content of seedling, the same for days of dry with water loose, meanwhile, days for drying had negative relation with moisture content. The survival rate was the highest when planting while removing or one day water immersion of root.Moisture content of seedling should be over 52%.
