摘要
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。
Base on the experimental material of almond cuhivar Zhipi in Shache town, the effect of N,P, K fertilizer application meth- ods 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.
