摘　　要：为了给本地区葡萄生产施肥提供理论基础,观测了典型农户的葡萄肥料投入量、葡萄产量和经济效益以及葡萄氮磷钾养分吸收分配。结果表明,本地区葡萄种植户肥料投入量氮肥1757 kg/hm 2、磷肥2152 kg/hm 2、钾肥1561 kg/hm 2,远超本地区推荐施肥量,氮、磷、钾有机养分投入量分别占总养分的投入量的36.8%、32.6%和62.6%。葡萄氮养分吸收总量为100.42 kg/hm 2,N素收获指数0.43;磷养分吸收总量为61.96 kg/hm 2,P素收获指数为0.48;钾养分吸收量148.29 kg/hm 2。K素收获指数0.53。氮、磷、钾养分吸收比例约为10.621.48。In order to provide a theoretical basis for grape fertilization,the fertilizer amount of input into orchard,grape yield,economic benefit and the absorption and distribution of nutrient were observed.The results showed that the fertilizer input was much higher than the recommended fertilizer application in this region,1757 kg/hm 2 for N fertilizer,2152 kg/hm 2 for P fertilizer,1561 kg/hm 2 for K fertilizer.The ratio of organic nutrient input to total was 36.8%,32.6%and 62.6%,N absorption of grape for custom fertilization was 100.42 kg/hm 2,and N harvest index was 0.48,while 61.96 kg/hm 2 and 0.48 for P,and 148.29 kg/hm 2 and 0.53 for K.The nutrient absorption ration of N,P and K was 10.621.48.
