巴旦木配方施肥效应研究

Study on the Effect of Formulated Fertilization in Almond

以新疆巴旦木主栽品种为试材,采用三因素四水平设计方案,在新疆喀什莎车县设置田间试验,运用数学模型对结果进行统计分析,找出最佳施肥配方。施氮肥对产量增产有比较明显的效果,施磷肥也有一定的增产作用,施钾肥增产效果不明显;与对照相比,处理8（N3P2K2）的产量达到了极显著水平,产量最高（2 143.65 kg/hm2）,两年最高产量施肥量N、P2O5、K2O分别为472.05,206.55,37.95 kg/hm2。氮磷钾各因素对产量的增产效果为N〉P〉K,确定最佳氮磷钾施肥量范围分别为N：600~720 kg/hm2;P2O5：401~480 kg/hm2;K2O：41~60 kg/hm2,三者施肥配比为1∶0.67∶0.08。

Based on the designed plan with 3 factors and 4 levels,a field experiment was conducted in Shache County of Xinjiang,taking local almond-main cultivar as test materials,the experimental results were statistically analyzed with mathematical model to find the optimum formulated fertilization.The application of N had better effect on yields comparing with P fertilization,and the application of K had no significant effect on almond yields.Contrasting with the control,the yield of almond with treatment 8 was the significant level,its the highest yield was 2 143.65 kg/hm2,the highest quantities of fertilizers application for two years were N：472.05 kg/hm2,P2O5：206.55 kg/hm2,K2O：37.95 kg/hm2 respectively.The results showed that the order of the increasing production of alll the factors was NPK.The optimum quantities of fertilizer application for almond were N：600-720 kg/hm2,P2O5：401-480 kg/hm2,K2O：41-60 kg/hm2 respectively,and the combination of fertilizers application of N,P and K was 1∶0.67∶0.08.
