不同基质配比对金雀花扦插生根的影响

Effects of Different Substrate Ratio on the Rooting of Cutting of Caragana microphylla

为促进金雀花的商品化生产,以生长健壮、无病虫害的2年生金雀花枝条为扦插材料,采用细沙、红土、珍珠岩、腐叶土、草炭土、泥炭土不同组合配比为扦插基质,采用随机区组设计进行金雀花扦插试验,研究不同基质配比对金雀花扦插生根的影响。结果表明:当基质细沙∶红土=4∶1配比对金雀花的扦插效果最好,生根率为92.6%,发芽率为86.0%。

In order to promote the commercial production of Caragana microphylla,the cuttings of 2-year-old broom branches were made from fine sand,red soil,perlite,humus soil,turfy soil and peat soil,a randomized block design was used to study the effects of different media ratio on the rooting of broom cuttings.The results showed that 4∶1 ratio of fine sand and red soil had the best cutting effect,the rooting rate was 92.6%,and the germination rate was 86.0%.
