不同氮、磷、钾配比追肥对初结果花椒树产量和品质的影响

Effects of Rates of Different Nitrogen,Phosphorus and Potassium Fertiliser on the Yield and Quality of First Fruit-bearing Zanthoxylum bungeanum

摘要: 以初结果花椒树为试验材料，研究不同配比的氮、磷、钾作为花前追肥对产量和品质的影响，以期为花椒初结果树追肥提供理论依据。研究结果表明，不同氮、磷、钾配比的追肥可显著提高初结果花椒树的产量与品质，最佳的追肥模式为采摘后施用1kg·株^-1尿素，花前追施尿素163g·株^-1，磷肥750g·株^-1，钾肥250g·株^-1。

Abstract: The experiment was conducted for providing theoretical basis on first bearing Zanthoxylum bungeanum in use of different nitrogen,phosphorus and potash fertilizer.The results showed that different rate of N,P,K could improve yield and quality significantly.The best model of fertilization included the application of 1 kg urea per plant after harvesting and the topdressing of 163 g,163 g of urea,750 g of P and 250 g K per plant in the beginning of blooming period.
