果园土壤与柑桔品质

Relationship between Quality of Orange and Soil in Orchard

土壤和施肥因素对柑桔品质影响较大。经研究表明，柑桔含糖量和土壤有效磷、钾含量呈曲线正相关。适当施用磷钾肥有利于改善柑桔品质。通过扩穴改土，由根际局部熟化到全园熟化，同时增施磷钾肥，可为提高柑桔品质，加快形成丰产稳产的强健树势打下良好的基础。

? Soil and fertilizer factors affect the quality of the orange greatly.The results indicated that sugar content of the orange has a positive curvilinear correlation with the effective phosphate and potassium applied.Dressing adequately P and K fertilizer is of benefit to improving the quality.By extending the planting hole and improving the soil,soil is humificated from root around to all orchard and then these are the base for increasing the orange quality and tree vigor.
