为给南疆巴旦木合理施肥提供科学依据,以南疆巴旦木主栽品种为试材,采用"3414"试验方案中的部分设计方案,在新疆喀什莎车县就氮、磷、钾肥的不同用量与配比对巴旦木产量的影响情况进行了田间试验,并运用数学模型对试验结果进行了统计分析.结果表明:氮、磷、钾各因素对巴旦木增产影响的大小依次为N>P>K,与对照相比,处理VIII(N_3P_2K_2)的产量最高(8496.90kg·hm~-2),增产比率最明显(71.13%),达到了极显著水平;获得最高产量的N、P_2O_5、K_2O的施入量分别为472.05、206.55、37.95kg·hm~-2;获得当年产量的N、P_20_5、K_20的施人量的参考值分别为354～531,232.4～348.6,23.7～35.56 kg·hm~-2,其配比为1.00∶0.67∶0.08.%In order to provide scientific basis for rational fertilization in almond in the south of Xinjiang, taking main cultivars of almond in the south of Xinjiang as materials, the effects of N, P and K fertilization on almond yield were researched based on “3414” fertilizer experiment protocol, and the test result was analyzed by mathematical model.The results showed that increase production effect of N, P and K factors on the yields was N＞P＞K.Contrasting with the blank control, the output of treatment Ⅷ was with the best level (8 496.90 kg · hm-2 ) and the rate of growth (71.13％), and the fertilizing amount of N, P2O5 and K2O were 472.05, 206.55 and 37.95 kg · hm-2, respectively.the reference value of fertilizing amount of N, P2O5 and K2O were 354-531, 232.4-348.6, 23.7-35.56 kg·hm-2, and the proportion of fertilizers application was 1.00 : 0.67 : 0.08.
