摘要
为摸清陕西省安康市千亩示范村植烟田土壤养分供应能力,解决当地烤烟生产中的施肥问题,于2022—2023年采集安康市烤烟千亩示范村40户烟农植烟田土壤样品273份,统计植烟田的海拔并测试土壤pH、有机质含量、碱解氮含量、有效磷含量、速效钾含量等指标。结果表明,安康市千亩示范村植烟田位于海拔630~1450 m,平均海拔为932 m,土壤平均pH为6.76,有机质、碱解氮、有效磷和速效钾平均含量分别为16.29 g/kg、69.74 mg/kg、40.33 mg/kg和162.83 mg/kg。综合分析上述指标,将安康市千亩示范村植烟地块划分为3个等级,其中一级地块占70.0%,二级地块占17.5%,三级地块占12.5%,评价结果认为安康市千亩示范村大部分地块适宜种植烤烟。
To investigate soil nutrient supply capacity of tobacco planting fields in the thousand acre demonstration villages in Ankang City,Shaanxi Province,and solve fertilization problems of tobacco planting,273 soil samples from 40 tobacco farmers in the thousand acre demonstration villages in Ankang City from 2022 to 2023 were collected,altitudes of tobacco planting plots were calculated,and contents of soil indicators such as soil pH,organic matter,alkaline nitrogen,available phosphorus,and available potassium were tested.The results showed that altitudes of tobacco planting fields in the thousand acre demonstration villages were from 630 m to 1450 m,and average altitude was 932 m,the average soil pH was 6.76,and the average contents of organic matter,alkali nitrogen,available phosphorus and available potassium were 16.29 g/kg,69.74 mg/kg,40.33 mg/kg and 162.83 mg/kg,respectively.Based on the comprehensive analysis of the above indicators,tobacco planting fields in the thousand acre demonstration villages in Ankang City were divided into three levels,with 70.0%fields of the first level,17.5%fields of the second level,and 12.5%fields of the third level.According to the evaluation results,most fields in the thousand acre demonstration villages in Ankang City were suitable for tobacco planting.
