Taking the current year sprouting branchlets of 3-year-old female Catalpa bungei tree as experimental materials,a randomized complete block design was adopted to study the effects of magnetic treatment on the rooting of C.bungei cuttings.Cuttings were subjected to the treatments of magnetization blanket+ magnetized water(MW+MR),magnetization blanket(MR),magnetized water spray(MW)and non-magnetized water spray(control).The research aim was to explore the magnet effect on cutting slip rooting and biomass accu...
