The Effect of Different Substrates on the Root System of Lonicera caerulea L.with Hardwood Cutting
Used Lonicera caerulea L.variety'Blue Elf'as test materials,investigated the growth of Lonicera caerulea L.hard branches roots under mixed substrates(peat soil∶perlite∶river sand=2∶1∶1),perlite,river sand,and their combined application with ABT.The research results showed that the mixed substrate(peat soil∶perlite∶river sand=2∶1∶1)+ABT had the highest rooting rate of 91.67%,and the root geometry characteristics were the best.Among them,the root length and root surface area of extremely fine roots and fine roots with a diameter of less than 2.0 mm accounted for more than 98%and 90%of the total root length and total surface area,respectively,which was conducive to the absorption of water and nutrients.
