| Abstract: | Objective]This paper studied the effects of fertilizer amounts on the growth and physiological characters of Nadina domestica seedlings.Methods]The test was conducted under the field condition?3 fertilization treatments,including the control group(CK),the conventional fertilization(T50),and the incremental fertilization(T100),were set up.The important growth and physiological indexes of Nadina domestica were measured.Results]The results showed that the order of the height,biomass,nitrate nitrogen,and nitrate reductase of Nadina domestica seedlings with different fertilization treatments were as follows:T50>T100>CK.Conclusion]By comprehensive evaluation,the optimum fertilizer amount was 25g/m2. |
