油茶轻基质网袋育苗施肥技术

以良种油茶轻基质网袋容器嫁接苗为试验材料,设计了轻基质网袋摆放厢床施肥和容器袋内施肥2种方式、多种施肥量的处理试验,用以研究施肥对油茶轻基质网袋容器育苗的成活率、抽梢率和苗木生长的影响。结果表明,不同施肥处理中油茶各项生长指标显著不同。厢床施用0.15 kg/m2复合肥、轻基质网袋容器内配1 g/袋过磷酸钙或网袋内配0.5 g/袋过磷酸钙+1 kg复合肥/m3处理的油茶轻基质网袋容器苗的成活率在90%以上,抽梢率达到85%,抽梢长度和粗度生长也具有显著优势。

Fertilization techniques of light matrix mesh-bag container seedlings for Camellia oleifera

The effects of fertilization methods(plot fertilization and fertilization in bag) on survival rate,shooting rate,growth of light matrix mesh-bag container seedlings of Camellia oleifera were studied.The results showed that there were significant differences in those growth indexes between fertilization methods.In the treatments spayed 0.15 kg/m2 compound fertilizer in plot fertilization,calcium superphosphate 1g per bag in light media mesh bag container or calcium superphosphate 0.5 g per bag+1 kg/m3 compound fertilizer,the survival rate was above 90%,shooting rate was 85%.Shooting length and width also had significant advantages compared with the other treatments.
