Abstract:
Taking 160-day-old seedlings of Pinus yunanensis as test materials,and the L9(34) orthogonal design was applied to implement cultivating the seedling experiment of three factors (each factor including three levels) which of non-woven fabric container size,matrix and fertilization in order to understand effects of factorial levels and their treatment combinations on seedling growth,basal diameters and seedling heights for 190-day-old and 250-day-old.The results showed that mean diameters and seedling heights were 1.19-1.72,1.89-2.32 mm and 1.26-3.40,3.11-4.09 cm for 190-day-old and 250-day-old seedlings.There were significant differences of basal diameters and seedling heights between treatment combinations for two age stages of the seedlings (P<0.01).There were also presented significantly different effects of basal diameters and seedling heights between the factorial levels of container size,matrix and fertilization (Root Doctor,a kind of water soluble fertilizer) solution concentration for two age stages′ seedlings (P<0.01),which indicated that it had dynamic requirements of the spaces and nutrients with Pinus yunnanensis seedling growth;the mixed matrix of forest soil,carbon residues and perlite which were portions of 6∶3∶1 could improve seedling growth.The seedling height and basal diameter had a linear correlation of y=1.232 2x+0.801 3.
