Reproduction Test on Taxus cuspidata Tree Top Cuttings
Making use of Taxus cuspidata tree top of artificial cultivating as cuttings, and carrying on cuttings propagation experiment. The test scheme was employed four different cutting matrices and ABT reagent 50 ×10-6 , 100×10-6 at two kinds of mass fractions and immersed treatment 8,16 hours to observe root condition of cuttings. The results showed that:four different cutting matrices had no significant effect on the rooting rate of cuttings. The rooting rate of cuttings had no significant difference at different mass fractions and different treatment times in ABT. Compared with the previous branch cuttings,rooting rate of tree top cuttings was significantly higher. The mixed matrix in forest soil and coarse sand facilitates growth of cuttings trunk than the other three kinds of matrixes. The results provide the basis for growing seedings rapidly wish pruning bushy tree tops.
