| 摘 要： | 通过2年田间小区试验研究不同用量长效复合肥添加剂(NAM)在茶树上的应用效果.结果表明,随添加剂用量的增加,土壤中铵态氮含量逐渐升高,硝态氮含量逐渐降低,表明添加剂能减慢铵态氮向硝态氮的转化.随添加剂(NAM)用量的增加,茶青产量先增加后降低,以添加7.5‰NAM处理的茶青产量和百芽重最高,2010年和2009年茶青产...

| Abstract: | A 2-year field experiment was conducted to study the effect of the long-term compound additives(NAM) in varying quantities on the tea trees.The results showed that increased NAM caused gradual increase on NH+4-N and reduction on NO-3-N.The additive slowed down the conversion of NH+4-N to NO-3-N.With the additon of NAM,tea yield was increased initially,and then,decreased.Both yield and hundred-bud-weight of green tea peaked when 75% NAM was applied.The yield was more than 5.20% in 2010,and 2.64% in 2009,as compared to the control.The increasing rates on tea yield,bud density and hundred-bud-weight were higher in 2010 than 2009.And,the NH+4-N and NO-3-N contents in the soil were also higher in 2010 than 2009.Thus,it was concluded that NAM application could inhibit urea hydrolysis and ammonium nitrification resulting in savings on labor fertilizer. |
