摘要
对取自漳州地区南靖、芗城、平和、长泰4个县(区)0～40 cm土层的122个蕉园土壤样品进行分析,结果表明漳州蕉园土壤存在的主要问题有:土壤pH偏低,90.98％的土样pH<5.5;部分土壤氮、钾、钙、镁、硼含量较低,其中55.74％的土样碱解氮、20.49％土样速效钾、52.46％土样交换性钙和38.52％土样交换性镁的含量分别低于100 mg·kg-1、80 mg·kg-1、2.5 cmol(+)·kg-1和0.4 cmol(+)·kg-1,所有土样的有效硼含量均低于0.5 mg·kg-1。据此提出相应的土壤培肥、合理施肥和缺素矫治措施。
The results of soil fertility of 122 soil samples from Nanjing, Xiangcheng, Pinghe and Changtai Counties were as follow; pH of 90. 98% of soil was lower than 5. 5 and the soils were acid, available N content in 55. 74% of soil samples were lower than 100 mg · kg-1, available K content in 20. 49% of soil samples were lower than 80 mg· kg-1, exchangable Ca content in 52. 46% of soil samples were lower than 2. 5 cmol ( + ) · kg-1, exchangable Mg content in 38. 52% of soil samples were lower than 0. 4 cmol( + ) · kg-1,available B content in all soil samples were lower than 0.5 mg · kg-1. Based on the data, measures of soil fertilization, reasonable fertilizing and remending practice of deficiency symptom were put forward.
