摘要：

为解决上海崇明柑橘黄化、树体弱和产量下降等问题，对其配施有机肥与微生物肥，研究不同有机肥施肥量和施肥深度对柑橘园土壤肥力和柑橘养分、品质的影响。结果表明：与对照处理相比，混施有机肥与微生物肥可以不同程度地增加土壤中速效N、有效P和有效K的含量，最好的处理分别高出对照6.4%、24.7%和24.9%；并能提高土壤有机质的含量，其中混施40 kg有机肥与微生物肥的处理效果最好，高出对照15.6%，从而提高土壤肥力；混施有机肥与微生物肥料可以不同程度的增加土壤微生物的数量，并且能提高土壤中速效微量元素的含量及柑橘叶片中全氮和全钾及微量元素铜、锌、铁与镁的含量。

Abstract:

Effects of Manure And Microbial Fertilizer on citrus showed that: in comparison with CK, organic fertilizer and microbial fertilizer can increased available N,P,K contents in varying degrees, compared with CK ,as the treatment of CK’s 6.4%,24.7% and 24.9%. and it can also enhanced the organic matter content of soil, the treatment of Comparison by manure(40kg)and microbial fertilizer increased within 15.6%;and decreased the soil bulk density, reduced soil pH, to improve the soil fertility. The number of fungi, bacteria were more than CK , but the number of ray fungi was a bit less than CK in the treatment of manure. And it also can improve leaf nutrient.
