摘要
对漳州市种植年限10 a以上主要蕉园土壤养分状况进行调查及评价,为漳州市香蕉园的土壤管理、合理施肥和香蕉产业的可持续发展提供参考。结果表明:漳州市蕉园土壤酸性较强,有机质含量处于中等偏下水平;92.31%的蕉园土壤碱解氮偏低;92.31%的有效磷含量处于极高水平;84.62%的蕉园土壤速效钾处于较高水平。对于中微量元素而言,84.62%的蕉园土壤交换性钙、92.31%的有效硫含量处于适宜香蕉生长的范围,30.77%的土壤交换性镁处于缺乏状态;土壤微量元素中有效铁、有效锰、有效铜、有效锌含量丰富,但92.31%的蕉园土壤有效硼含量低于临界值,硼素缺乏严重。因此,为了实现蕉园合理施肥和可持续发展,漳州市长期蕉园应施用石灰类物质或其他碱性肥料提高土壤pH,增施有机肥培肥地力;在施用化肥时,重施氮肥,适量施用硼砂和有机硼肥,适当减少钾肥用量,部分地区增施镁肥。
Zhangzhou is the main banana producer in Fujian,A comoprehensive analysis of soil nutrient status of aged banana gardens in Xiangcheng,Nanjing,Pinghe,Longhai,Zhangpu of Zhangzhou,was carried out in the study.And recommendations for the fertilization were put forward,aiming to provide a scientific basis for local soil nutrient management.Results show that,soil pH values in all gardens was below 5.5,and soil organic matter contents were all less than 30 mg/kg.92.31％ of gardens soil nitrogen content was less than 100 mg/kg,and nitrogen content in soil was low.Soil available phosphorus values were all higher than 10 mg/kg,at a very high level.Soil available potassium values of all gardens were more than and 100 mg/kg,and 84.62 ％ of soil available potassium values in f banana gardens were at a high level.84.62％ of soil exchangeable calcium values and 92.31％ of soil available sulfur values of all banana gardens were in the effective range suitable for banana,but 30.77％of soil exchangeable magnesium values at the deficient level.The available copper,iron and manganese content of all fields were higher than their responding critical value respectively,and 84.62％ of extremely available zinc values were very rich,but 92.31％ of soil boron values were less than its critical value.In order to achieve the rational fertilization of aged banana gardens in Zhangzhou,regulation soil pH with lime,dolomite or other alkaline fertilizers,and application of organic fertilizer,nitrogen and boron fertilizer,are required.Less potassium fertilizer,no addition of phosphorus,calcium,sulfur,iron,manganess and zinc fertilizer,are recommendated as well.
