我省各地,由于多年来用泡桐埋根苗造林,以致丛枝病蔓延,为害严重。虽有报道,用播种苗造林丛枝病显著减轻,但播种苗苗期生长较慢,1年生苗多不能出圃造林。为了解决这个问题,我们从1983年开始,在苗床内铺设加温线,作成电热温床,外搭塑料薄膜拱棚,培育成泡桐容器苗,然后移植在大田,效果很好。两年来共生产苗木2万余株,1年生苗高一般在3～5米,地径4～5.2厘米,超过1年生埋根苗。现将育苗技术介绍于下,以供参考。一、需要的设备:1.催芽绿化室:10米~2小房一间,室内 Throughout our province, due to many years of plantation with Paulownia seedlings, resulting in the spread of broom disease, serious damage. Although it has been reported that planting sowing shrubs significantly reduce the afforestation, but sowing seedling growth is slower, more than 1 year old nursery afforestation. In order to solve this problem, we started in 1983, laying heating lines in the seedbed, made electric hotbed, outside the plastic film arch shed, cultivate into Paulownia container seedlings, and then transplanted in the field, the effect is very good. Over the past two years, more than 20,000 seedlings have been produced. The annual height of 1-year-old seedlings is generally 3 to 5 meters and the diameter is 4 to 5.2 centimeters. Breeding technology now introduced below, for reference. First, the equipment needed: 1. Germination green room: 10 m ~ 2 small room, indoor
