我区已往引种湿地松采用大田直接播种育苗,此方法种子出土率低,易遭鼠、鸟等危害,且苗木质量差。近年我们采用室外塑料薄膜温床催芽移栽育苗,效益很好,现将情况简介如下。温床设计与催芽移栽温床制作:温床选在近水背风向阳的圃地范围内。温床长3—4米,宽1米。床四周用砖、石灰砂砌。放入厚25—30厘米的清水河砂铺平,用1‰新洁而灭溶液消毒。床框架斜面上每隔25—30厘米放置一条小山竹(或小木棍),盖上薄膜待播。种子消毒:将种子投入1%硫酸铜溶液或1‰新洁而灭溶液消毒20—30分钟。温水催芽:把消毒处理的种子置于50—60℃温水中浸24小时。捞起凉干,用40—
My area has been introduced in the past Slash pine directly sowing seedlings, the method of low rate of excavated seeds, susceptible to rats, birds and other hazards, and poor quality seedlings. In recent years, we use outdoor plastic film hotbed germination transplanting seedlings, good benefits, the situation is summarized as follows. Hotbed design and germination transplanting Hotbed production: Hotbed selection in the near water leeward sunny range of land. Hotbed 3-4 meters long and 1 meter wide. Around the bed with brick, lime sand. Into the 25-30 cm thick water river pave, with 1 ‰ neo-Jie and eliminate the solution disinfection. Place a small bamboo (or small wooden stick) every 25-30 cm on the bevel of the bed frame and cover with the film to be sowed. Seeds disinfection: the seeds into 1% copper sulfate solution or 1 ‰ Neo Jie eliminate the solution disinfection 20-30 minutes. Warm water sprouting: The sterilized seeds were immersed in warm water at 50-60 ℃ for 24 hours. Pick up and dry, with 40-
