- 摘要:
- 以香樟一年生半木质化枝条为试材，采用开放、完全封闭、半封闭3种栽培模式，每种模式设大田土基质和混合基质2个处理进行扦插繁殖，以探索适合苏北地区环境条件的香樟扦插繁殖栽培模式。结果表明：半封闭模式09:00温度在13.0~25.6 ℃，湿度在90%~94%，15:00温度在23.8~28.5 ℃，湿度在88%~94%。半封闭模式的平均成活率为72.05%，平均生根率为74.8%，平均保存率为79.4%，均高于开放模式和完全封闭模式。3种模式中混合基质处理的平均成活率、平均生根率和平均保存率分别为60.2%、73.6%、67.8%，均高于大田土基质处理，半封闭模式中混合基质处理的扦插效果综合评价得分最高。半封闭模式的平均根数为4.22条，平均根长为15.44 cm，平均根粗为1.155 mm，均高于开放模式和完全封闭模式。3种模式中混合基质处理的平均根数、平均根长和平均根粗为3.89条、13.47 cm、0.91 mm，均高于大田土基质处理，半封闭式混合基质处理的根系效果指数最高，其综合生根能力最强。半封闭式混合基质处理最适合在苏北地区香樟的扦插繁殖。
- Abstract:
- Cinnamomum camphora annual semi lignified branches were taken as materials,in order to study the best breeding cultivation mode of environmental conditions in Northern Jiangsu on camphor cuttings,using open mode(A),fully closed mode(B),semi closed mode(C),which included field soil and mixed substrate soil two soil treatments for cutting propagation.The results showed that the temperature was 13.0-25.6 ℃,humidity at 90%-94% at 09：00 am,at 23.8-28.5 ℃,humidity was 88%-94% at 15:00 pm.The mode C average survival rate,average rooting rate and the average survival rate was higher than that of mode A,B,the average survival rate of mode C was 72.05%,the average rooting rate was 74.8%,average preserving rate of mode C was 79.4%.The average survival rate,average rooting rate and the average survival rate of the mixed substrate soil were 60.2%,73.6% and 67.8%,respectively,20.9%,24.1% and 11.7% higher than that in the field soil.The comprehensive evaluation of the cutting of mixed media in the model C was the highest.The mode C average number of root was 4.22,the average root long was 15.44 cm,the average root crude was 1.155 mm.The average root number,average root length and average root diameter of mixed matrix were 3.89,13.47 cm and 0.91 mm,respectively,22.3%,11.2%,9.6% higher than that in the field soil.The root effect index of mixed matrix treatment of mode C was the highest,and the comprehensive rooting ability was the strongest.Mixed matrix treatment of mode C was suitable for camphor cutting in northern Jiangsu.
