摘要
通过连续3年的田间定位试验,研究了不同氮磷钾肥配比对陕西关中地区猕猴桃品质、产量和经济效益的影响。结果表明,与对照(CK)相比,不同氮、磷、钾配比处理均增加了猕猴桃Vc、可溶性糖含量和单果质量,使猕猴桃产量增加13.6%-30.1%,平均每年可增加产量3.7-8.2 t/hm^2,增加纯收入3.1-8.3千元/hm^2。氮、磷、钾平衡施用处理在增加叶片中矿物质营养,改善品质,增产和提高经济效益方面效果最佳。氮、磷、钾肥对当地猕猴桃产量的贡献率顺序为氮肥〉钾肥〉磷肥,不同肥料配比的纯收入大小顺序为NKK〉NK〉NP〉PK。
This experiment used 3 years continual fixed site field trials to study on the effect of N,P and K fertilizer application on kiwifruit quality,yield and profit in Guanzhong area of Shaanxi.The result showed that N,P and K fertilizer application increased the content of Vc and soluble sugar in kiwifruit,increased the single fruit weight.The treatments of fertilizer applied made the kiwifruit yield increased 3.7~8.2 t/ha per year than CK,with the increased percentage of 13.6% ~ 30.1%,and made the net profit increased 3.1~8.3 qianyuan/ha per year.Balanced application of N,P and K is the best way to increase the plant nutrient cumulation,yield and economic benefits,and to improve kiwifruit quality.The order of contribution of N,P and K on kiwifruit yield is: NKP.The order of fertilizer application on net profit is NPKNKNPPK.
