摘  要：
2013年选取并分析了河南省漯河市烟区25个乡镇的植烟土壤养分状况,结果表明:随着植烟土壤土层深度的增加,土壤p H值保持基本稳定,整体呈弱碱性;而土壤有机质、碱解氮、速效磷、速效钾、全氮含量和土壤碳氮比值均呈递减趋势,表现为0~10 cm>10~20cm>20~30 cm>30~40 cm>40~50 cm。漯河市烟区植烟土壤养分含量在不同土层间表现差异。0~10 cm土层土壤有机质、碱解氮、速效磷、速效钾、全氮含量均显著高于10 cm以下土层(P<0.05),耕层土壤(0~20 cm)养分状况明显优于20 cm以下土层,且达到0.05显著水平。漯河市烟区0~20 cm耕层土壤主要养分平均含量和碳氮比等指标变异较大,且其土壤养分平均含量均高于0~50 cm土壤,0~50 cm深度范围内土壤的潜在养分水平表现不足,尤其是碳氮比值偏低,不够协调。

摘  要：
Soil samples of 25 tobacco planting townships were selected and nutrient content status of tobacco planting area of Luohe City of Henan Province in 2013 was analyzed. The results showed that with increasing of depth of tobacco planting soil,soil p H value maintained basic stability,and overall performance of soil was slightly alkaline.However,soil organic matter content,available nitrogen content,available phosphorus content,available potassium content,total nitrogen content and ratio on carbon and nitrogen of soil(C/N)showed a decreasing trend with increasing depth of soil,their performances were 0~10 cm>10~20 cm>20~30 cm>30~40 cm>40~50 cm. Soil nutrient content of tobacco planting area in Luohe City varied from different soil layers. Organic matter content,available nitrogen content,available phosphorus,available potassium content,total nitrogen content in 0~10 cm depth of soil were significantly higher than 10 cm below it(P<0.05),soil nutrient status of plow layer(0~20 cm)was significantly better than 20 cm below soil,and the differences between them reached 0.05 level of significance. Average content of main soil nutrients,C/N ratio of soil and other indicators on farming soil in 0~20 cm depth have greater variation of tobacco planting area in Luohe City. Average content levels of soil nutrients in 0~20 cm depth were higher than soil nutrient levels in 0~50 cm depth,potential nutrient content level on soil of 0~50 cm depth was inadequate,especially C/N ratio of soil was low and not coordination.
