长期施用氮磷钾肥对黄土高原地区苹果产量及土壤养分累积与分布的影响OA北大核心CSCDCSTPCD
Effect of long-term application of nitrogen, phosphorus and potassium on apple yield and soil nutrient accumulation and distribution in orchard soil of Loess Plateau
对连续8a施用氮磷钾肥的黄土高原地区‘红富士’苹果园的产量及土壤养分变化进行了研究，以探明长期施用氮磷钾化肥对苹果产量与土壤养分累积与分布的影响。结果表明，施用氮磷钾化肥（NPK处理）显著增加了苹果产量，增产率为12．8％。128.3％，增产率随施肥年限增加有增加趋势。NPK处理增加了果园土壤的有效氮、磷、钾含量，其累积量在不同土层中的分布差异较大。与对照（CK）相比较，NPK处理使0—20cm、20～40cm和40～60cm土层中的速效氮含量平…查看全部>>
Eight-year experiments （from 2001-2009） in apple orchard were conducted to evaluate the ef- fects of long-term application of nitrogen, phosphorus and potassium （NPK） on apple yield and soil nu- trient accumulation and distribution in orchard soil of Loess Plateau in Shaanxi province. The results showed that apple yields were increased varying from 12.8% to 128.3% annually through NPK, and the yield-increasing effects were very different every year. Compared…查看全部>>
