中文摘要:
      研究分析了武陵山区恩施州巴东县野三关镇5个村的代表性高山蔬菜种植地的肥力特征,结果表明:调查区为酸性土壤,土壤肥力充足;有机质、有效钾、全氮和钙含量处于Ⅰ级的土样分别占总土样数的43.30%、78.33%、93.33%和98.33%;磷和镁含量均在Ⅰ级以上;硼含量均高于Ⅴ级;硒含量均大于0.4 mg/kg,属富硒土壤. 根据研究结果,建议该地区菜地在1~2个种植年内减少相关肥料的施用,跟踪检测土壤肥力,科学合理培肥. 当地农民可以开展富硒特色高山蔬菜产品的开发.
英文摘要:
      This study analyzed the soil fertility characteristics of typical high mountain vegetable cultivation fields of Yesanguan town in Badong County, Enshi Prefecture of Wuling Mountain Area. The results showed that the investigated area were acid soils and the soils were fertile. The contents of organic matter, available potassium, total nitrogen and calcium reaching Grade I accounted for 43.3%, 78.33%, 93.33% and 98.33% of the total samples, respectively. The phosphorus and magnesium contents of all soil samples were above Grade I and the boron content of all soil samples exceeded Grade Ⅴ. The selenium content of all soil samples was above 0.4 mg/kg: so the investigated soils were selenium enrichment. Accordingly, the application amount of the above fertilizers should be reduced in the investigated vegetable fields in 1-2 years. Meanwhile, the soil fertility characteristics of the investigated area should be tracked monitoring for scientific fertility betterment, and the local farmers can develop high mountain selenium-rich vegetables to get more economic benefit.
