摘要
【目的】为提高沙地葡萄产量和改善其品质,【方法】2009—2010连续两年在科尔沁沙地上采用"3414"二次回归最优设计方案,进行田间试验,研究氮(X1)、磷(X2)、钾(X3)肥施用对葡萄产量和品质的影响。【结果】葡萄产量与肥料用量之间的数学模型Y=1189.48+3698.50X1+1533.2X2+1182.61X3-1159.97X12-464.23X22-369.68X32+78.46X1X2-54.69X1X3+175.22X2X3,施肥量为N 24.23 kg·667 m-2;P2O537.98 kg·667 m-2;K2O 84.84 kg·667 m-2,最高产量可达7023.22 kg·667 m-2。【结论】综合考虑产量和品质,处理N1P2K2的效果最佳。
[Objective]The objective of the study is to enhance yield and to improve quality of grape in Horqin sandy land [Method]The field trial was conducted to explore the effect of nitrogen, phosphorus and potassium on yield and quality of grape by using ＂3414＂ optimal design of quadratic regression method in 2009--2010. [Result]The results showed that the mathematical model between grape yield and fertilization was. The highest yield was 7023.22 kg ＂667 m-2 When the fertilization amount was N 24.23 kg＇667 m-z, P205 37.98 kg-667 m-z and K20 84.84 kg＇667 tv. N,P,K was the ontimum treatment in the exnerirnnt [Conclusion]Considering yield and quali-ty, was the optimum treatment in the experiment.
