利用四倍体刺槐的根段进行容器苗繁殖,方法简单快捷,成本低成活率高,易于移栽和运输,是扩繁和推广四倍体刺槐种植地域的基本方法之一。为了降低生产成本,下面介绍利用农村普通的蔬菜温室大棚进行种苗扩繁的方法。大棚准备工作1.环境设施:农用节能日光温室大棚,大棚后墙每间隔8米、距地1.5米处应有一换气通风口(最好安装有双向排风扇和挡风棉帘)。光照:光照强度控制在5000Lux 左右。温度:控制在15～25℃,基质温度能保持在15～20℃,避免空气与基质温差太大。湿度:育苗期保持在60～90%,湿度达不到70%时,应及时采取相应措施增加湿度。2.工具:剪刀、塑料盆、温度计、湿度计、地膜、石蜡、铁铲、喷雾器等。
The use of tetraploid Robinia pseudoacacia root segments for container seedling propagation, the method is simple and fast, low cost and high survival rate, easy to transplanting and transportation, is to expand and promote tetraploid Robinia pseudoacacia planting area of one of the basic methods. In order to reduce production costs, the following describes the use of rural common greenhouse greenhouse seedling expansion method. Preparation of greenhouse 1. Environmental facilities: Agricultural energy-saving greenhouse, greenhouse back wall at intervals of 8 meters, 1.5 meters away from the place should have a ventilation vents (preferably equipped with two-way exhaust fan and wind cotton curtain). Light: light intensity control in about 5000Lux. Temperature: controlled at 15 ~ 25 ℃, the substrate temperature can be maintained at 15 ~ 20 ℃, to avoid too much air and the substrate temperature difference. Humidity: Seedling maintained at 60 ~ 90%, humidity less than 70%, should take timely measures to increase the humidity. 2. Tools: scissors, plastic basin, thermometer, hygrometer, mulch, paraffin, shovel, sprayer and so on.
