| 摘 要： | 分析了陕西关中地区葡萄园土壤的养分状况,并在此基础上通过连续4年的平衡施肥试验,研究了葡萄养分平衡施肥技术体系及其对葡萄产量、品质和经济效益的影响。结果表明,试验区葡萄园分别有100%,97.8%和58.7%的土壤样品有效N、F e和Zn含量处于临界值以下;化肥对葡萄产量的增产率为12.4%~38.0%,各种肥料对葡萄产量贡献率大小的顺序为:氮肥>钾肥>磷肥,钾肥对葡萄品质有明显促进作用;氮磷钾平衡施用才能使葡萄产量最高、品质最佳、效益较好;葡萄养分平衡施肥体系为:N 0.18 kg/株,P2O50.15 kg/株,K2O 0.2 kg/株,并增施适量铁、锌微肥。

| Abstract: | Totally 64 soil samples were taken in grid from grapery in Xinji village of Shaanxi Guanzhong area.The test result by ASI indicates the contents of available N,available Fe and available Zn that of 100%,97.8% and 58.7% soil samples are under the critical value.The(4-year) field trials show that fertilizer supply could increase grape yield in the range of 12.4%-38.0%.The order of increase rate among N,P,and K was N>P>K.Only the balanced supply of N,P and K could make the grape yield,quality and benefit best.The reasonable quantity of fertilization should be N 0.18 kg/tree,P_2O_5(0.15 kg/tree),K_2O 0.2 kg/tree per year,in addition to some Fe fertilizer and Zn fertilizer. |
