- 摘要:
- 以芙蓉菊为试材，采用沙壤土、细河沙、蛭石+珍珠岩（2∶1）、草炭土+珍珠岩（2∶1）、细河沙+珍珠岩（2∶1）、沙壤土+珍珠岩（2∶1）、蛭石+珍珠岩+草炭土（1∶1∶1）等7种基质，选用IBA、ABT-2生根粉2种外源激素，激素处理的浓度梯度为200、400、800 mg?L-1，处理的时间梯度为10、15、30 s，研究了不同基质与不同外源激素及浸泡时间对芙蓉菊扦插生根效果的影响，以期优化芙蓉菊扦插技术。结果表明：蛭石+珍珠岩+草炭土（1∶1∶1）是芙蓉菊扦插最理想的基质，扦插成活率为95%；沙壤土+珍珠岩（2∶1）则有利于芙蓉菊幼苗生长健壮，壮苗率为67.5%；IBA、ABT-2对芙蓉菊的扦插生根均有促进作用，而以浓度400 mg?L-1 ABT-2生根剂处理插穗30 s，其插穗成活率、壮苗率最高，分别为97.5%、78.8%；800 mg?L-1 IBA处理插穗10 s，也能有效促进插穗生根，其插穗成活率、壮苗率分别为72.5%、53.0%。确定芙蓉菊扦插育苗最优组合为蛭石+珍珠岩+草炭土（1∶1∶1）为基质，用400 mg?L-1 ABT-2生根剂处理插穗30 s。
- Abstract:
- Crossostephium chinense was used as test materials,using seven kinds of different substrates of sand,sandy loam,vermiculite+perlite（2∶1），peat soil+perlite（2∶1）,sand+perlite（2∶1）,sandy loam+perlite（2∶1）,vermiculite+perlite+peat soil（1∶1∶1）,using IBA,ABT-2 rooting powder of two kinds of hormones,hormone concentration gradient processing time gradient 200，400，800 mg?L-1 and treating as 10 seconds,15 seconds,30 seconds,effects of different substrates and different exogenous hormone and immersing time on Crossostephium chinense cuttings were studied,in order to optimize Crossostephium chinense cutting technology.The results showed that vermiculite+perlite+peat soil (1∶1∶1) was the most ideal Crossostephium chinense cuttings matrix,survival rate of cuttings was 95%;silty loam+perlite (2∶1) matrix was conducive to Crossostephium chinense seedling growth strong,rate of strengthen seedling was 67.5%.IBA,ABT-2 to Crossostephium chinense cuttings rooting had promote role,and to a concentration of 400 mg?L-1 ABT-2 rooting agent 30 seconds,cutting rooting effect was the best,survival rates of cutting was 97.5%,rate of strengthen seedling was 78.8%；800 mg ?L-1 IBA and 10 seconds could effectively promote the cuttings rooting,survival rate of cutting was 72.5%,rate of strengthen seedling was 53.0%.Therefore,the optimal combination of vermiculite+perlite+peat soil (1∶1∶1) as matrix,with 400 mg?L-1 ABT-2 cuttings rooting agent processing 30 seconds.
