具有完整发达的根系是壮苗的重要指标之一。油茶系轴状型深根性树种,主根深长、侧须根稀少,植苗造林往往成活率较低。为了促使油茶播种苗侧须根的发生,培育壮苗,以期提高造林成活率,我们于1973年和1978年在农学院教学苗圃,曾结合教学进行过湿沙催芽断胚根育苗和切根育苗比较试验,1979年在麻江县林科所继续进行研究,现小结于后。 Roots with a well-developed root is one of the important indicators of strong seedlings. Camellia deep-rooted shaft type tree species, the main root deep, scarce side of the fibrous roots, planting and afforestation often lower survival rate. In order to promote the sowing of Camellia oleifera side fibrous roots, nurturing strong seedlings, in order to improve the survival rate of afforestation, we in 1973 and 1978 teaching nursery in Agronomy, have been combined with teaching wetting bud germination and root cutting seedling cutting comparison Test, in 1979 Ma Linjiang Branch continue to carry out research, are summarized in later.
