【摘要】 以早实核桃辽核4号初果期树为研究材料,采用N、P、K"3414"最优回归设计方案,研究了配方施肥对于核桃总蛋白和总脂肪含量的影响。研究发现配方施肥可以明显地提高核桃总蛋白和总脂肪的含量,且N、P、K施肥量与核桃总蛋白和总脂肪含量均符合三元二次回归方程的肥料效应函数规律。通过肥料效应函数分析得出能有效提高核桃总蛋白和总脂肪含量的施肥范围为N施用量在869.31¹ 082.01g/株,P₂O₅施用量在513.26⁵22.50g/株,KO₂施用量在434.65⁵04.65g/株。研究结果为关中台田上通过配方施肥提高核桃果实的品质提供了理论依据。更多还原

【Abstract】 Taking‘LiaoHe 4’,an early fruit cultivar of Juglans regia as research object,the effects formulated fertilization in which the best regressive fertilizing program ‘3414’design with nitrogen（N）,phosphorus（P）and potassium（K）fertilizers were adopted on the content of total protein and fat were tested.The results showed that the total protein and fat were improved by fertilizing N,P and K,and the fertilizing effect accorded with ternary quadratic equation.The effective fertilizing extent to improve the content of total protein and fat were N 869.31-1 082.01 g,P2_O5 513.26-522.50 g and KO2434.65-504.65 g per tree.The research results provide a scientific basis for field fertilizing management to improve the Juglans regiafruit quality on the terrace in the Guanzhong area.更多还原
