花木扦插培育的研究

为了更好地培育花木,于1985年在哈尔滨实验林场利用太阳能增温床对多种花木进行了扦插研究。太阳能增温床是揉合塑料棚、温室和电温床的技术原理而设制的。在太阳能增温床上进行插穗,培育花木,能为插穗创造一个底温高,表温低,相对湿度大的良好生根条件。因此,能够促进插穗早愈伤早生根,根系发育良好,成活率高。该床与温室和电温床相比有突出的节能特性,特别适合于那些结实少,种子发芽困难和稀有珍贵树种的繁殖。此项技术,不但可在林业、苗圃、花圃等部门推广应用,同时在有关农业部门也能应用。

STUDY ON CULTURE OF CUTTING FLOWERS AND TREES

In order to culture better flowers, test of cutting of flowers on solar energy hotbed was made in Harbin experimental forest farm in 1985. Solar energy hotbed was made according to the principle of making plastic tent, conservatory and electric hotbed. It can supply a better condition of higher bottom temperature, lower surface temperature, and higher relative humidity for rooting. It can also accelerate cutting wood wounded and root early, solar energy hotbed saves energy evidently compared to conservatory and electric hotbed. It is suitable to reproduction of trees which bear little and germinate difficultly. The hotbed is not only used in forestry, nursery, but also in agriculture.
