不同轻基质配方对油茶苗木生长的影响

摘要

以椰糠为基本原料,通过与泥炭土、菌渣和木屑按不同比例混合配置了10种轻基质配方,并从根、茎、叶三方面系统的研究这10种配方对岑软3号小苗嫁接苗生长的影响。研究结果表明：除配方6（椰糠：木屑：泥炭土,9∶3∶1）和7（椰糠：木屑：泥炭土,6∶3∶1）外,剩余8种配方都适合做岑软3号小苗嫁接苗的基质,其中配方1（椰糠：泥炭土,4∶1）对茎和叶生长的促进作用最为明显,配方3（椰糠：菌渣,3∶1）和4（椰糠：菌渣,2∶1）对根系生长有明显的促进作用。%Using coconut coir as the basic material,ten fertilizer formulas were formulated by mixing peat soil,mushroom dregs and saw dust.Effects of the ten light medias on the seedlings growth of Camellia oleifera were studied by measuring root,stem and leaf.Results showed that all fertilizer formulas are suitable for seedlings growth of Camellia oleifera except formula 6（coconut coir： saw dust： peat soil = 9∶3∶1） and 7（coconut coir： saw dust： peat soil = 6∶3∶1）.Formula 1（coconut coir： peat soil = 4∶1） significantly improved the growth of stem and leaf,while formula 3（coconut coir：mushroom dregs = 3∶1） and 4（coconut coir： mushroom dregs = 2∶1） significantly benefited growth of root.
