云南省保山市咖啡园土壤养分特征及肥力综合评价
Soil nutrient characteristics and comprehensive fertility evaluation of coffee orchards in Baoshan City,Yunnan Province
摘要
Abstract
To provide scientific guidance for precise soil nutrient management and coffee quality improvement in coffee orchards of Baoshan City,Yunnan Province,the soil nutrient contents in local coffee orchards were systematically evaluated by the comprehensive soil fertility index method.Soil samples were collected from five typical coffee planting areas in Baoshan City,and soil indicators in-cluding pH,organic matter,total nitrogen,total phosphorus,total potassium,manganese,zinc and copper contents were determined.The comprehensive index of soil fertility was calculated by the membership function model to comprehensively assess the soil nutrient characteristics and fertility of coffee orchards in Baoshan City.The results showed that the soil of coffee orchards in Baoshan City was generally acidic,with pH of 4.30-7.02 and an average value of 5.47.The contents of soil organic matter,total nitrogen,total phospho-rus,total potassium,manganese,zinc and copper were 26.50-61.80 g/kg,0.63-2.51 g/kg,0.19-1.96 g/kg,21.80-41.90 g/kg,241.00-2 550.00 mg/kg,33.70-200.00 mg/kg and 8.94-57.20 mg/kg,with average values of 40.59 g/kg,1.18 g/kg,0.68 g/kg,28.52 g/kg,882.31 mg/kg,87.58 mg/kg and 29.61 mg/kg,respectively.The average contents of all indicators met the suitable levels for cof-fee growth.The comprehensive index of soil fertility of coffee orchards in Baoshan City was 0.21-0.67,with an average of 0.44.Accord-ing to the comprehensive evaluation criteria of soil fertility,the soil fertility was classified as Grade Ⅲ,belonging to the medium level on the whole.It was recommended to reasonably increase the application rates of nitrogen and phosphorus fertilizers on the basis of in-creasing organic fertilizer input.Meanwhile,the input of trace elements such as manganese,zinc and copper in soil should be appro-priately controlled.The above measures could effectively maintain high yield and high-quality production of coffee in Baoshan City,and support the quality improvement,efficiency enhancement and green sustainable development of the local coffee industry.关键词
