氮磷钾配方施肥对南疆扁桃产量的影响

以莎车县扁桃品种纸皮为试验材料,通过果园田间肥料试验,研究了不同氮、磷、钾肥配比对扁桃产量的影响。结果表明:合理施用氮、磷、钾肥有利于提高扁桃坚果的产量,与不施肥(对照)处理相比,各施肥处理扁桃的产量均显著增加(P<0.05),但是各处理之间的扁桃产量有所差异,以处理12(施肥配方氮磷钾比例为1:2.0:0.9)的扁桃产量和经济效益最高。每年施尿素102 g/株,磷酸二铵922 g/株和硫酸钾477 g/株,比不施肥处理增产160 kg/667 m2,增收2 702元/667 m2。综合扁桃产量、经济效益和肥料产投比分析,扁桃较合理氮磷钾比例为处理12,在此条件下,扁桃平均产量可达到258.9 kg/667 m2。

Effect of N、P and K Fertilizer Application Methods on Yield of Almond in South Xinjiang

Base on the experimental material of almond cultivar Zhipi in Shache town,the effect of N,P,K fertilizer application methods on yield of almond was studied through fertilizer experiment on the orchard field.The results showed that the almond yield increased with the suitable ratio of N,P and K fertilizer.Compared with control,the almond yield of different fertilizer application increased significantly(P<0.05),whereas the yields of almond were different among all fertilization treatments.The highest almond yield and economic benefit was gained with the N:P:K=1:2.0:0.9,which were urea 102 g/plant,di-ammonium phosphate 922 g/plant,potassium sulfate 477 g/plant,and with the increased almond yield 160 kg/667 m2 and increased income 2 702 RMB/667 m2 compared with control.The treatment 12(N:P:K=1:2.0:0.9),was the best based on the comprehensive analysis of the yield,economic efficiency and ratio of output to input,and with the average yield of almond was up to 258.9 kg/667 m2.
