Effect of different seedling densities on the growth of Koelreuteria elegans seedlings
In order to achieve scientific seedling cultivation of Koelreuteria elegans and cultivate large landscaping trees,this article analyzes the growth of Koelreuteria elegans seedlings under different seedling densities,and studies the effects of seedling density on four indicators of survival rate,seedling height,ground diameter,and crown width of the tree species.Research has shown that seedling density has a certain impact on the growth of four indicators,including survival rate,seedling height,ground diameter,and crown width,of Koelreuteria elegans seedlings;Among 5 different seedling density treatments,the survival rate of Koelreuteria elegans seedlings was the best at seedling densities of Processing 3(9 cm × 9 cm),Processing 4(12 cm × 12 cm),and Processing 5(15 cm × 15 cm);The height growth of Koelreuteria elegans seedlings is optimal at seedling densities of Processing 3(9 cm × 9 cm),Processing 4(12 cm × 12 cm),and Processing 5(15 cm × 15 cm);The ground diameter growth of Koelreuteria elegans seedlings is optimal under seedling densities of Processing 4(12 cm × 12 cm)and Processing 5(15 cm × 15 cm);The crown width growth of Koelreuteria elegans seedlings is optimal under a seedling density of Processing 5(15 cm × 15 cm).Based on comprehensive analysis,it could be concluded that under different seedling density treatments,the survival rate,seedling height,ground diameter,and crown width of Koelreuteria elegans seedlings under a seedling density of Processing 5(15 cm × 15 cm)showed overall good growth,which was suitable for promotion.
