| Abstract: | The effects of different N,P,K fertilizer formulas on the growth of potted Begonia X sempertlorens-cuhorum Hort. were researched. The results showed that the fertilization formula of N ： P ： K=2 ： 1 ： 4 had a significant effect on the growth of plant height and crown diameter of Begonia X semperflomns-cuhorum Hort.; the formula of N ： P ： K=2 ： 1 ： 2 was most conducive to the growth of plant canopy and leaf area; the formula of N ： P ： K=2 ： 1 ： 4 could increase the plant chlorophyll, plant fresh weight and dry weight of Begonia X sempertlorens-cultorum Hort.; and was conducive to the growth of the plant; the formula of N ： P ： K=2 ： 1 ： 4 could advance the flowering phase of Begonia X sempertlorenss-cuhorum Hort. and also extended the flowering period to as long as 45days. To sum it up, the formula of N ： P ： K=2 ： 1 ： 4 was the optimal formula of the fertilization for raising high-quality potted Begonia X sempertlorenss-cuhorum Hort. |
