| 摘 要： | 以绿化9号品种为调查对象,2006年调查了平谷区141个桃园的施肥现状及其对土壤养分和桃果品质的影响。结果表明:所调查的桃园施用的有机肥以鸡粪、羊粪、猪粪、牛粪为主,化肥投入以复合肥居多;与2004年的调查结果相比,2006年来自有机肥和化肥的总N投入数量下降,但是P、K投入总量增加;由于桃园多年的过量养分投入,2006年桃园土壤有机质、全氮、碱解氮、有效磷和速效钾含量比1981年第二次土壤普查结果均有大幅度提高;调查结果还显示,养分投入为适宜等氮素投入水平(100～200kghm-2)、中磷素投入水平(20～100kghm-2)和低钾素投入水平(50kghm-2)的桃园桃果实单果重较大,可溶性固形物含量较高,因此,桃园要进行合理的养分管理以保证产量和品质的形成,以及桃园的可持续发展。

| Abstract: | With the Green No.9 peach as investigation object,141 peach orchards in Pinggu district were investigated for fertilization and its effects on soil nutrient contents and peach fruit quality in 2006.The survey results showed that the main organic fertilizers in Pinggu district were chicken,sheep,pig and cattle manure,and chemical fertilizer was mainly compound fertilizer.Comparing to 2004,the amount of total N input from chemical and organic fertilizer decreased while those of P2O5 and K2O increased in 2006;... |
