摘要
对马蹄"3414"肥料田间试验。结果表明:供试田块氮、磷、钾肥施用量与产量有显著的回归关系;应用回归方程分析,获得最佳施肥量为:N 268.5 kg/hm2,P2O5154.5 kg/hm2,K2O 352.5 kg/hm2,该肥力条件下马蹄最佳产量46 332.0 kg/hm2。
through the water chestnut ＂3414＂ effects of fertilizer field experiments, analysis under certain soil fertility applying n, p, k content, ratio and water chestnut production relations. Experimental results show that the selected field applying NPK fertilizer content and yield a significant regression relationship; Under the condition of application of regression equation analysis, the fertility of water chestnut optimal output 46 332.0 kg/hm2, best fertilizer rate is： N 268.5 kg/hm2, P205 154.5 kg/hm2, K20 352.5 kg/hm2.
