为了提高油茶嫁接苗成活率和促进其快速生长,以黄心土、菜园土、黄心土∶菜园土=3∶7、黄心土∶菜园土=7∶3和轻基质等5种不同试验处理,研究了不同基质类型对油茶嫁接苗成活及生长发育的影响.结果表明:不同基质类型对油茶嫁接苗成活率、抽梢率、苗高和地径都有显著影响.以轻基质和菜园土处理效果较好,成活率达94.44%以上,抽梢率达93.33%以上,苗高达7.95cm以上,地径达1.80mm以上;经相关分析,苗高和地径极显著正相关,R=0.982 5**;经回归分析,苗高和地径间回归方程为y=0.902 7+0.111 2x.
In order to improve the survival rate and promote the rapid growth of Camellia oleifera grafted seedlings, five different treatments including yellow soil, vegetable garden soil, yellow soil soil: garden soil = 3: 7, yellow soil soil: garden soil = 7: 3 and light medium were studied. Type on the survival and growth of Camellia oleifera grafted seedlings.The results showed that: different substrate types had significant effects on the survival rate, shoot-cutting rate, seedling height and diameter of grafted Camellia oleifera seedlings, The survival rate was above 94.44%, the shoot-tip rate was above 93.33%, the shoot height was above 7.95cm, and the diameter reached 1.80mm. The correlation analysis showed that there was a significant positive correlation between seedling height and ground diameter, R = 0.982 5 **. Regression analysis showed that the regression equation between height and diameter was y = 0.902 7 + 0.111 2x.
