不同用量长效复合肥添加剂(NAM)在茶树上的应用效果
Effect of Long-term Compound Additives on Tea Plants
摘要
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.关键词
