南疆巴旦木测土配方施肥效果试验初报

Preliminary study of fertilizer response on soil testing and formulated fertilization in almond in the south of Xinjiang

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（N3P2K2）的产量最高（8 496.90 kg.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、P2O5、K2O的施入量分别为472.05、206.55、37.95 kg.hm-2;获得当年产量的N、P2O5、K2O的施入量的参考值分别为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 NPK.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.
