摘　　要：为掌握丽水市莲都区蔬菜土壤酸化状态,为相关防控工作提供依据,采用野外土壤pH值快速测定方法,对丽水市莲都区碧湖镇15个村、峰源乡6个村的蔬菜基地土壤pH值进行速测,调查蔬菜土壤酸化现状。结果表明:220个测点的土壤pH值区间在4.1~6.5,其中有173个测点为强酸性(<4.5,1级)及酸性(4.5~5.5,2级)土壤,占比为78.6%;另有47个测点为微酸性(5.6~6.5,3级)土壤,占比为21.4%;中性(6.6~7.5,4级)、微碱性(7.6~8.5,5级)、碱性(>8.5,6级)的土壤均为0;且设施菜地酸化程度明显高于露地菜地。针对丽水市莲都区蔬菜土壤酸化严重的现状,提出采用氰氨化钙处理酸化土壤后配施微生物菌肥的改良技术,可实现土壤pH值提升0.71,土壤有机质含量提升5.8%。In order to understand the status of soil acidification of vegetables in Liandu district of Lishui city and provide the basis for relevant prevention and control work,a rapid field soil pH value determination method was adopted,the present situation of vegetable acidified soil in 15 villages of Bihu town and 6 villages of Fengyuan town in Liandu district of Lishui city was investigated by measuring soil pH value.The results showed that the soil pH values of 220 sites ranged from 4.1 to 6.5,of which 173 sites were strongly acidic(4.5,grade 1) and acidic(4.6-5.5,Grade 2),accounting for 78.6%.The other 47 sites were 21.4% of slightly acidic(5.6-6.5,grade 3),and none of neutral(6.6-7.5,grade 4),slightly alkaline(7.6-8.5) and alkaline(8.5,grade 6).The degree of acidification in protected vegetable field was significantly higher than that in open field.In view of the serious situation of vegetable soil acidification in Liandu district of Lishui city,the improvement technology of applying microbial fertilizer after calcium cyanamide treatment of acidified soil was proposed to increase soil pH value by 0.71 and the content of soil organic matter by 5.8%.
