Effect of Different Ways of Treating Sandy Cypress Mother Plants on Rooting of Cuttings
Using sandy cypress as the material,a one-way test was carried out under four different treatments on the mother plant of sandy cypress,with yellowing,ring stripping,urea spraying and NAA spraying as the experimental groups,and water treatment as the control,to analyze the rooting process of the scions in terms of the rooting rate,the decay rate,the average number of roots and the rooting index,as well as the rooting process and its type of rooting,and to carry out a multi-comparison and a comprehensive evaluation of their rooting effects.The results showed that using four different ways of treating shoots and hardwood spikes,the highest rooting rate and rooting index were in NAA treatment,which were 84.43%and 92.76,76.67%and 76.74,respectively.The comprehensive evaluation showed that the NAA treatment had the best rooting effect on the cuttings,which was better than the other treatments.
