Abstract

Abstract

It is of great significance to study the influence of NO₃^--N,NH₄⁺-N and (-CONH₂) on the growth and development of bamboo shoots,so as to provide a theoretical for the growth regulation and quality cultivation of Bambusa emeiensis and to reduce the nitrogen pollution in forest. By setting 4 treatments,the control group (CK) was only applied with phosphate fertilizer and potassium fertilizer,T₁ was applied with (-CONH₂),phosphate fertilizer and potash fertilizer,T₂ was applied with NO₃^--N,phosphate fertilizer and potash fertilizer,T₃ was applied with NH₄⁺-N,phosphorus fertilizer and potash fertilizer,the effects of different forms of nitrogen fertilizer on the growth and development of Bambusa emeiensis were studied. The results showed that the dynamics of the shooting number of Bambusa emeiensis showed an s-shaped curve for all treatments of different forms of nitrogen fertilizer. The daily average cumulative shooting number of amide-nitrogen fertilizer treatment was the highest,which was 1.23 times higher than that without nitrogen fertilizer treatment. The second was the nitrate nitrogen fertilizer treatment,which was 1.19 times higher than that without nitrogen fertilizer treatment,while the lowest was the ammonium nitrogen fertilizer treatment. The shooting number treated with amide nitrogen fertilizer was the most,while that treated without nitrogen fertilizer treatment was the least. The lignifications of the shoots treated with ammonium nitrogen fertilizer was earlier than that treated with amide nitrogen and nitrate nitrogen fertilizer.
