摘要

摘要: 研究浆用慈竹笋生长发育的适宜氮肥形态，对提高竹笋发笋量、生长量以及促进次生细胞壁的增厚和减少林田的氮污染具有重要意义，为慈竹的合理调控和优质栽培提供理论依据。研究设置4个处理，对照组（CK）仅施入磷肥和钾肥，T₁施入酰胺态氮及磷肥和钾肥，T₂施入硝态氮及磷肥和钾肥，T₃施加铵态氮及磷肥和钾肥，研究不同形态氮肥对慈竹生长发育的影响。结果表明：不同形态氮肥处理的竹笋发笋量的动态变化都呈现出"S"型曲线。酰胺态氮处理的累计日均发笋量最高，是未施入氮肥处理的1.23倍，其次为硝态氮处理，是未施入氮肥处理的119%，铵态氮处理最低。酰胺态氮肥处理竹笋的发笋量最多，而不施氮处理的最小。铵态氮肥处理的竹笋木质化要早于酰胺态氮和硝态氮处理。

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.
