英文摘要:
      Using the completely random design and the single factor design, respectively, effects of media and cutting type on the rooting ability of Chinese fir cuttings were studied by the semi-lignified branches collected from superior trees in the seed orchard of Chinese fir in Hezhou. The results indicated that 5 cm cuttings in sand reached the highest survival rate with 100% while 9 cm cuttings were satisfied in the mixed medium of sand and perlite (1颐1) with 100% rooting rate and best morphologic characters. The root activity was the top in 7 cm cuttings and the mixed medium of sand and perlite (1颐1). The root of crown segments grew vigorously although its survival rate and rooting rate were lower than those of stem section. As a whole, 7~9 cm cuttings benefited the rooting in the mixed medium of sand and perlite (1颐1), which may enhance the cuttage reproduction quality of Chinese fir.
