研究根据树种的生物学特性,采用人工控制调节苗木生长所需的环境,将传统的露地育苗转变为工厂化的气切根法育苗,使苗木生长发育所需的营养基质、温度、光照、湿度和CO_2等因子采用人工调控,从种子到苗木出厂造林的各个生产环节,均在育苗机械设备的控制下,生产出优质的容器苗。通过研究建成了华南林木容器育苗实验工厂,厂址设在广西横县县城附近,占地0.5公顷,设有三栋育苗塑料大棚网室(共
According to the biological characteristics of tree species, artificial control of the growth of seedlings required for the environment, the traditional open-field seedling transformed into industrialized gas-cut root method of seedling growth, growth and development of nursery stock nutrients, temperature, light, humidity And CO_2 and other factors using manual control, from seed to seedling factory afforestation in all aspects of production, are under the control of nursery machinery and equipment to produce high-quality container seedlings. Through the research, we built the South China Forest Container Nursery Experimental Plant with an area of 0.5 hectare and located in Hengxian County, Guangxi Province. There are three nursery plastic greenhouse
