Effects of Combined Application of Nitrogen Phosphorus and Potassium on the Growth of Toona ciliata
In order to investigate the effects of combined application of nitrogen,phosphorus and potassium on the growth of Toona ciliata,eight treatment groups were set up by pot experiment,including no fertilization group,single application of nitrogen,single application of phosphorus,single application of potassium,combined application of nitrogen and phosphorus,combined application of phosphorus and potassium,and combined application of nitrogen,phosphorus and potassium on the growth of Toona ciliata.The results showed that the combined application of N,P and K could significantly promote the growth of Toona ciliata,and ζ(N∶P∶K)=2∶1∶1 was the best for the growth of Toona ciliata.
