| 摘 要： | 通过对河南洛阳基本烟田不同茬口105个土壤样品分析,评价了洛阳基本烟田主要茬口植烟土壤的养分现状。结果表明:不同茬口(烟草、红薯、花生、大豆、谷子、芝麻、玉米、辣椒)土壤有机质含量平均为1.31%,其平均含量大小顺序为辣椒花生大豆谷子烟草芝麻红薯玉米;不同茬口土壤有效氮介于1.00%~1.50%之间,由低到高排列为辣椒花生谷子烟草大豆芝麻红薯玉米,需注意氮肥使用量;不同茬口土壤全磷含量低于优质烟叶生产的适宜范围或在范围下限,需要增施磷肥并提高磷素有效性;不同前茬作物对土壤缓效钾、速效钾的影响都较小,均在生产优质烟叶的土壤速效钾含量范围内;不同茬口土壤水溶性氯含量之间差异较小,介于4.79~5.76 mg/kg之间,较为适宜生产优质烟叶;不同茬口土壤有效B、有效Cu处于缺乏至极度缺乏状态;不同茬口土壤有效Mn含量差异较大,处于丰富至极度缺乏状态;不同茬口土壤有效锌、有效铁含量处于中等供应水平。 |

| Abstract: | The status of soil fertility in the basic tobacco fields with different previous crops in Luoyang was evaluated based on the analysis of 105 soil samples from the basic tobacco fields with different previous crops.The results showed that the average content of soil organic matter in tobacco fields with different previous crops was 1.31%,which was suitable to produce high-quality tobacco leaves,and the order of the previous crops based on the content of soil organic matter in tobacco fields was: chilli |
