柑桔植株要求营养物保持在一定范围内以维持高产和保持良好的品质。施肥的目的是使植株有适宜的营养物质供应,但施肥过量,成本太高,而且并非有增产效果。此外,某些营养元素过量常常使果实品质降低。不论任何地区的果园,都没有一直不变的施肥标准。土壤的理化性能变化,果园的管理习惯,砧木的种类,气候因素如降水量的多少都将影响植株对营养物质的有效吸收,柑桔植株需肥量的最好指标是 Citrus plants require that nutrients be kept within range to maintain high yields and maintain good quality. The purpose of fertilization is to make the plants have adequate supply of nutrients, but over-fertilization, the cost is too high, and not yield stimulation. In addition, excessive use of certain nutrients often lowers fruit quality. No matter the orchard in any area, there is no constant fertilization standard. Changes in physical and chemical properties of soil, orchard management practices, rootstock species, climate factors such as the amount of precipitation will affect the plant’s effective absorption of nutrients, citrus plants need fertilizer is the best indicator of
