摘要:
为研究高效简易的南京椴绿枝扦插技术，以半木质化绿枝为插穗，采用覆膜小拱棚加遮阳网等简易设施，开展了扦插方式、扦插基质及插穗长度对插穗生根的影响试验。试验结果表明，就地扦插和采用营养钵扦插2种方式的插穗生根率均在75%以上；不同基质和插穗长度对南京椴扦插生根具有显著影响，生根率最高的分别是单一基质园土、复合基质草炭+园土(容积比为2∶1)，而等容积珍珠岩+草炭+园土复合基质在生根率和根系质量2项指标方面效果最优；长10—12 cm的插穗生根率可达83.43%，根系质量也较优。在该试验优化扦插条件下，上述2种扦插方式均可获得良好的生根效果，并建议生产上使用长10—12 cm插穗、等容积混合的珍珠岩+草炭+园土复合基质。
Abstract:
In order to acquire simple and efficient cutting technology of Tilia miqueliana, the influence of cutting mode (in situ or in container), cutting substrate and cuttage length on rooting was studied by using the semi-lignified green branches and the simple facilities of small arch shed covered with film and shading net. The results showed that the cuttage rooting rate both in situ and in container could exceed 75%; Different substrates and cuttage length had significant effects on rooting. The higher cuttage rooting rate could get in both single garden soil and the composite substrate as peat+garden soil (volume ratio 2:1), and the composite substrate as perlite+peat+garden soil (equal volume mix) presented best in both rooting rate and root system quality of cuttage. The rooting rate of 10—12 cm long cuttage reached 83.43%, also with better root system quality. Under the optimized cutting conditions, both of the above-mentioned two green branch cutting modes of T. miqueliana could get good rooting effects. In production, the practice of taking 10—12 cm long semi-lignified green branches in the composite substrate as perlite+peat+garden soil (equal volume mix) could be recommended.
