泡桐火炕催芽育苗,出土早(比直接埋根早20天左右)、出苗齐、树苗壮、反苗快、成活率高。经试验成功后,于1978年在13个公社,1,500个生产队实行了泡桐火炕催芽育苗。据调查,桐苗当年高生长在4.5米以上,地径6厘米以上,每亩出圃优质壮苗可达450株左右,出圃率比直接埋根和苗床苗都有显著提高。现将火炕催芽方法介绍如下: 一、催芽育苗时间:种根3月5日至10日下池,于3月 Paulownia kang germination nursery, unearthed early (20 days earlier than the direct buried root), the emergence of Qi, saplings Zhuang, anti-Miao fast, high survival rate. After successful tests, in 1978, 13 communes, 1,500 production teams practiced the Paulownia kang germination nursery. According to the survey, Tong Miao year high growth in more than 4.5 meters, more than 6 centimeters in diameter, acres of nursery stock up to about 450 high-quality nursery than directly buried roots and seedlings have significantly increased. Now kang germination methods are described below: First, germination nursery time: seedlings March 5 to 10 under the pool in March
